The Department of Economic and Social Affairs of the
United Nations Secretariat is a vital interface between
global policies in the economic, social and
environmental spheres and national action. The
Department works in three main interlinked areas: (i) it
compiles, generates and analyses a wide range of
economic, social and environmental data and
information on which States Members of the United
Nations draw to review common problems and to take
stock of policy options; (ii) it facilitates the negotiations
of Member States in many intergovernmental bodies on
joint courses of action to address ongoing or emerging
global challenges; and (iii) it advises interested
Governments on the ways and means of translating
policy frameworks developed in United Nations
conferences and summits into programmes at the
country level and, through technical assistance, helps
build national capacities.
NOTE
Symbols of United Nations documents are composed
of capital letters combined with figures. Mention of such
a symbol indicates reference to a United Nations
document.
The designations employed and the presentation of
material in this publication do not imply the expression
of any opinion whatsoever on the part of the Secretariat
of the United Nations concerning the legal status of any
country, territory, city or area, or of its authorities, or
concerning the delimitation of its frontiers or boundaries.
Where the designation "country or area" appears in
the headings of tables, it covers countries, territories, or
areas.
Le Département des affaires économiques et sociales
du Secrétariat de l’Organisation des Nations Unies sert
de relais entre les orientations arrêtées au niveau
international dans les domaines économiques, sociaux
et environnementaux et les politiques exécutées à
l’échelon national. Il intervient dans trois grands
domaines liés les uns aux autres : i) il compile, produit
et analyse une vaste gamme de données et d’éléments
d’information sur des questions économiques, sociales
et environnementales dont les États Membres de
l’Organisation se servent pour examiner des problèmes
communs et évaluer les options qui s’offrent à eux; ii) il
facilite les négociations entre les États Membres dans
de nombreux organes intergouvernementaux sur les
orientations à suivre de façon collective afin de faire
face aux problèmes mondiaux existants ou en voie
d’apparition; iii) il conseille les gouvernements
intéressés sur la façon de transposer les orientations
politiques arrêtées à l’occasion des conférences et
sommets des Nations Unies en programmes
exécutables au niveau national et aide à renforcer les
capacités nationales au moyen de programmes
d’assistance technique.
NOTE
Les cotes des documents de l'Organisation des
Nations Unies se composent de lettres majuscules et de
chiffres. La simple mention d’une cote dans un texte
signifie qu’il s’agit d’un document de l’Organisation.
Les appellations employées dans cette publication et
la présentation des données qui y figurent n'impliquent
de la part du Secrétariat de l'Organisation des Nations
Unies aucune prise de position quant au statut juridique
des pays, territoires, villes ou zones, ou de leurs

INTRODUCTION
The Demographic Yearbook is an international compendium of national demographic statistics
provided by national statistical authorities to the Statistics Division of the United Nations Department of
Economic and Social Affairs. The Demographic Yearbook is part of the set of coordinated and
interrelated publications issued by the United Nations and its specialized agencies, designed to supply
statistical data for such users as demographers, economists, public-health workers and sociologists.
Through the co-operation of national statistical services, available official demographic statistics are
compiled in the Demographic Yearbook for more than 230 countries or areas throughout the world.
The Demographic Yearbook 2009-2010 is the sixty-first in a series published by the United Nations
since 1948. It contains tables including a world summary of selected demographic statistics, statistics on
the size, distribution and trends in national populations, fertility, foetal mortality, infant and maternal
mortality, general mortality, nuptiality and divorce. Data are shown by urban/rural residence, as
available. In addition, the volume provides Technical Notes, a synoptic table, a historical index and a
listing of the issues of the Demographic Yearbook published to date. This issue of Demographic
Yearbook contains data as available including reference years 2009 and 2010. In population and vital
statistics tables presenting time series, the available data of reference years 2009 and 2010 are
presented. In the detailed population and vital statistics tables, presenting the latest available data, in
addition to the usual tables with the latest reference year 2009, additional tables with the available 2010
data are presented.
The Technical Notes on the Statistical Tables are provided to assist the reader in using the tables.
Table A, the synoptic table, provides an overview of the completeness of data coverage of the current
Demographic Yearbook. The cumulative historical index is a guide on content and coverage of all sixty-
one issues, and indicates, for each of the topics that have been published, the issues in which they are
presented and the years covered. A list of the Demographic Yearbook issues, with their corresponding
sales numbers and the special topics featured in each issue are shown on pages iii and iv.
Until the 48th issue (1996), each issue consisted of two parts, the general tables and special topic
tables, published in the same volume1
. Beginning with the 49th issue (1997), the special topic tables
were being disseminated in digital format as supplements to the regular issues. Two CD-ROMs have
been issued: the Demographic Yearbook Historical Supplement, which presents a wide panorama of
basic demographic statistics for the period 1948 to 1997, and the Demographic Yearbook: Natality
Statistics, which contains a series of detailed tables dedicated to natality and covering the period from
1980 to 1998. In addition, three volumes of Demographic Yearbook Special Census Topics are
published on-line at http://unstats.un.org/unsd/demographic/products/dyb/dybcens.htm. These volumes
cover the topics of basic population characteristics, educational and ethnocultural characteristics and
international migration characteristics. Current Demographic Yearbook census topics datasets for
reference years 1995 to present are presented at
http://unstats.un.org/unsd/demographic/products/dyb/dybcensusdata.htm. These datasets cover basic
population characteristics, educational, household, ethnocultural and economic characteristics, and also
foreign-born and foreign population.
Population statistics are not available for all countries or areas, for a variety of reasons. In an effort
to provide estimates of mid-year population and of selected vital statistics for all countries and areas, two
annexes are presented. Annex I presents United Nations population estimates for the period 2001-2010
and Annex II presents the medium variant estimates of crude birth and death rates, infant mortality and
total fertility rates, as well as life expectancy at birth over the period 2005-2010. These data were
produced by the United Nations Population Division and are published in the World Population Prospects
- The 2010 Revision
2
.

TECHNICAL NOTES ON THE STATISTICAL TABLES
1. GENERAL REMARKS
1.1 Arrangement of Technical Notes
These Technical Notes are designed to provide the reader with relevant information related to the
statistical tables. Information pertaining to the Demographic Yearbook in general is presented in the
sections dealing with geographical aspects, population and vital statistics. In addition, preceding each
table are notes describing the variables, remarks on the reliability and limitation of the data, countries and
areas covered, and information on the presentation of earlier data. When appropriate, details on
computation of rates, ratios or percentages are presented.
1.2 Arrangement of tables
The numbering of tables from one issue of Demographic Yearbook to the next is preserved to the
extent possible. However, since for some of the tables the numbering may not correspond exactly to
those in previous issues, the reader is advised to use the historical index that appears at the end of this
book to find the reference to data in earlier issues.
1.3 Source of data
The statistics presented in the Demographic Yearbook are national data provided by official
statistical authorities unless otherwise indicated. The primary source of data for the Demographic
Yearbook is a set of questionnaires sent annually by the United Nations Statistics Division to over 230
national statistical services. Data reported on these questionnaires are supplemented, to the extent
possible, with data taken from official national publications, official websites and through correspondence
with national statistical services. In the interest of comparability, rates, ratios and percentages have been
calculated by the Statistics Division of the United Nations, except for the life table functions, the total
fertility rate, and also crude birth rate and crude death rate for some countries or areas as appropriately
noted. The methods used by the Statistics Division to calculate these rates and ratios are described in
the Technical Notes for each table. The population figures used for these computations are those
pertaining to the corresponding years published in this or previous issues of the Demographic Yearbook .
In cases when data in this issue of the Demographic Yearbook differ from those published in earlier
issues or related publications, statistics in this issue may be assumed to reflect revisions to the data
received by June 2011.
2. GEOGRAPHICAL ASPECTS
2.1 Coverage
Data are shown for all individual countries or areas that provided information. Table 3 is the most
comprehensive in geographical coverage, presenting data on population and surface area for all
countries or areas with a population of at least 50 persons. Not all of these countries or areas appear in
subsequent tables. In many cases the data required for a particular table are not available. In general, the
more detailed the data required for a table, the fewer the number of countries or areas that can provide
them.
In addition, rates and ratios are presented only for countries or areas reporting at least a minimum
number of relevant events. The minimums are stated in the Technical Notes to individual tables.
Except for summary data shown for the world and by major areas and regions in tables 1 and 2 and
data shown for capital cities and cities with a population of 100 000 or more in table 8, all data are
presented at the national level. The number of countries shown in each table is provided in table A, the
synoptic table.

3
2.2 Territorial composition
To the extent possible, all data, including time series data, relate to the territory within 2010
boundaries. Exceptions are footnoted in individual tables. Relevant clarifications are specified below.
Data relating to Denmark exclude Faeroe Islands and Greenland, which are shown separately.
Data relating to Finland include Åland Islands, unless otherwise indicated by a footnote.
Data relating to France exclude Overseas Departments, namely, French Guiana, Guadeloupe,
Martinique and Réunion, which are shown separately, unless otherwise indicated by a footnote.
Data relating to Norway exclude Svalbard and Jan Mayen Island shown separately, if available.
Data relating to Sudan include South Sudan. The Republic of South Sudan formally seceded from
Sudan on 9 July 2011. However this issue of the Demographic Yearbook contains data for the reference
years up to 2010.
Data relating to United Kingdom of Great Britain and Northern Ireland exclude Guernsey, Isle of
Man and Jersey which are shown separately.
Data relating to Western Sahara comprise the Northern Region (former Saguia el Hamra) and
Southern Region (former Rio de Oro).
2.3 Nomenclature
Because of space limitations, the country or area names listed in the tables are generally the
commonly employed short titles currently in use
3
in the United Nations, the full titles being used only
when a short form is not available. The latest version of the Standard Country or Area Codes for
Statistics Use can be accessed at http://unstats.un.org/unsd/methods/m49/m49alpha.htm.
2.3.1 Order of presentation
Countries or areas are listed in English alphabetical order within the following continents: Africa,
North America, South America, Asia, Europe and Oceania.
The designations and presentation of the material in this publication were adopted solely for the
purpose of providing a convenient geographical basis for the accompanying statistical series. The same
qualification applies to all notes and explanations concerning the geographical units for which data are
presented.
2.4 Surface area data
Surface area data, shown in tables 1 and 3, represent the total surface area, comprising land area
and inland waters (assumed to consist of major rivers and lakes) and excluding only Polar Regions and
uninhabited islands. The surface area given is the most recent estimate available. They are presented in
square kilometres, a conversion factor of 2.589988 having been applied to surface areas originally
reported in square miles.
2.4.1 Comparability over time
Comparability over time in surface area estimates for any given country or area may be affected by
changes in the surface area estimation procedures, increases in actual land surface by reclamation,
boundary changes, changes in the concept of “land surface area” used or a change in the unit of
measurement used. In most cases it was possible to ascertain the reason for a revision; otherwise, the
latest figures have generally been accepted as correct and substituted for those previously on file.

4
2.4.2 International comparability
Lack of international comparability between surface area estimates arises primarily from differences
in definition. In particular, there is considerable variation in the treatment of coastal bays, inlets and gulfs,
rivers and lakes. International comparability is also impaired by the variation in methods employed to
estimate surface area. These range from surveys based on modern scientific methods to conjectures
based on diverse types of information. Some estimates are recent while others may not be. Since
neither the exact method of determining the surface area nor the precise definition of its composition and
time reference is known for all countries or areas, the estimates in table 3 should not be considered
strictly comparable from one country or area to another.
3. POPULATION
Population statistics, that is, those pertaining to the size, geographical distribution and demographic
characteristics of the population, are presented in a number of tables of the Demographic Yearbook.
Summary estimates of the mid-year population of the world, major areas and regions for selected
years and of its age and sex distribution in 2010 are set forth in tables 1 and 2, respectively.
Data for countries or areas include population census figures, estimates based on results of sample
surveys (in the absence of a census), postcensal or intercensal estimates and those derived from
continuous population registers. In the present issue of the Demographic Yearbook , the latest available
census figure of the total population of each country or area and mid-year estimates for 2005 and 2010
are presented in table 3. Mid-year estimates of total population for ten years (2001-2010) are shown in
table 5 and mid-year estimates of urban and total population by sex for ten years (2001-2010) are shown
in table 6. The latest available data on population by age, sex and urban/rural residence are given in
table 7. The latest available figures on the population of capital cities and of cities or urban
agglomerations of 100 000 or more inhabitants are presented in table 8.
The statistics on total population, population by age, sex and urban/rural distribution are used for the
calculation of rates in the Demographic Yearbook . Vital rates by age, sex and residence (urban/rural)
were calculated using data presented in table 7 in this issue or the corresponding tables of previous
issues of the Demographic Yearbook.
3.1 Sources of variation of data
The comparability of data is affected by several factors, including (1) the definition of total population;
(2) the definition used to classify the population into its urban/rural components; (3) the accuracy of age
reporting; (4) the extent of over-enumeration or under-enumeration in the most recent census or other
source of benchmark population statistics; and (5) the quality of population estimates. These five factors
will be discussed in some detail in sections 3.1.1 to 3.2.2 below. Other relevant problems are discussed
in the technical notes to the individual tables. Readers interested in more detail, relating in particular to
the basic concepts of population size, distribution and characteristics as elaborated by the United
Nations, should consult the Principles and Recommendations for Population and Housing Censuses,
Revision 24
.
3.1.1 Total population
The most important impediment to comparability of total populations is the difference between the
concept of a de facto and de jure population. A de facto population includes all persons physically
present in the country or area at the reference date. The de jure population, by contrast, includes all
usual residents of the given country or area, whether or not they were physically present in the area at
the reference date. By definition, therefore, a de facto total and a de jure total are not entirely
comparable.
Comparability of even two de facto or de jure totals is often affected by the fact that strict conformity
to either of these concepts is rare. For example, some so-called de facto counts do not include foreign
military, naval and diplomatic personnel present in the country or area on official duty, and their
accompanying family and household members; some do not include foreign visitors in transit through the
country or area or transients on ships in harbours. On the other hand, they may include such persons as
merchant seamen and fishermen who are temporarily out of the country or area working at their trade.

5
The de jure population figure presents even greater variations in comparability, in part because it
depends in the first place on the concept of “usual residence”, which varies from one country or area to
another and is difficult to apply consistently in a census or survey enumeration. For example, non-
national civilians temporarily in a country or area as short-term workers may officially be considered
residents after a stay of a specified period of time or they may be considered as non-residents throughout
the duration of their stay; at the same time, these individuals may be officially considered as residents or
non-residents of the country or area from which they came, depending on the duration and/or purpose of
their absence. Furthermore, regardless of the official treatment, individual respondents may apply their
own interpretation of residence in responding to the inquiry. In addition, there may be considerable
differences in the accuracy with which countries or areas are informed about the number of their
residents temporarily out of the country or area.
As far as possible, the population statistics presented in the tables of the Demographic Yearbook
refer to the de facto population. Those reported to have been based on the de jure concept are identified
as such. Figures not otherwise qualified may, therefore, be assumed to have been reported by countries
or areas as being based on a de facto definition of the population. In an effort to overcome, to the extent
possible, the effect of the lack of strict conformity to either the de facto or the de jure concept given
above, significant exceptions with respect to inclusions and exclusions of specific population groups, are
footnoted when they are known.
It should be remembered, however, that the necessary detailed information has not been available in
many cases. It cannot, therefore, be assumed that figures not thus qualified reflect strict de facto or de
jure definitions.
A possible source of variation within the statistics of a single country or area may arise from the fact
that some countries or areas collect information on both the de facto and the de jure population in, for
example, a census, but prepare detailed tabulations for only the de jure population. Hence, even though
the total population shown in table 3 is de facto, the figures shown in the tables presenting various
characteristics of the population, for example, urban/rural distribution, age and sex distribution, may be
on the de jure concept.
3.1.2 Urban/rural classification
International comparability of urban/rural distributions is seriously impaired by the wide variation
among national definitions of the concept of “urban”. The definitions used by individual countries or areas
and their implications are shown at the end of technical notes for table 6.
3.1.3 Age distribution
The classification of population by age is a core element of most analyses, estimation and projection
of population statistics. Unfortunately, age data are subject to a number of sources of error and
non-comparability. Accordingly, the reliability of age data should be of concern to users of these statistics.
3.1.3.1 Collection and compilation of age data
Age is the estimated or calculated interval of time between the date of birth and the date of the
census or survey, expressed in completed solar years5
. There are two methods of collecting information
on age. The first is to obtain the date of birth for each member of the population in a census or survey
and then to calculate the completed age of the individual by subtracting the date of birth from the date of
enumeration
6
. The second method is to record the individual’s completed age at the time of the census or
survey, that is to say, age at last birthday.
The recommended method is to calculate age at last birthday by subtracting the exact date of birth
from the date of the census. Some practices, however, do not use this method but instead calculate the
difference between the year of birth and the year of the census. Classifications of this type are footnoted
whenever possible. They can be identified to a certain extent by a smaller than expected population
under one year of age. However, an irregular number of births from one year to the next or age selective
omission of infants may also obscure the expected population under one year of age.

6
3.1.3.2 Errors in age data
Errors in age data may be due to a variety of causes, including ignorance of the correct age;
reporting years of age in terms of a calendar concept other than completed solar years since birth
7
;
carelessness in reporting and recording age; a general tendency to state age in figures ending in certain
digits (such as zero, two, five and eight); a tendency to exaggerate length of life at advanced ages; a
subconscious aversion to certain numbers; and wilful misrepresentations.
These reasons for errors in reported age data are common to most investigations of age and to most
countries or areas, and they may significantly impair comparability of the data.
As a result of the above-mentioned difficulties, the age-sex distribution of population in many
countries or areas shows irregularities which may be summarized as follows: (1) a deficiency in the
number of infants and young children; (2) a concentration at ages ending with zero and five (that is, 5, 10,
15, 20, ...); (3) heaping at even ages (for example, 10, 12, 14, ...) relative to odd ages (for example, 11,
13, 15, ...); (4) unexpectedly large differences between the frequency of males and females at certain
ages; and (5) unaccountably large differences between the frequencies in adjacent age groups.
Comparing of identical age-sex cohorts from successive censuses, as well as studying the age-sex
composition of each census, may reveal these and other inconsistencies, some of which in varying
degree are characteristic of even the most modern censuses.
3.1.3.3 Evaluation of accuracy
The publication of population statistics by single years of age in the Demographic Yearbook 1955
made it possible to apply a simple, yet highly sensitive, index known as Whipple's Index, or the Index of
Concentration
8
, the interpretation of which is relatively free from consideration of factors not connected
with the accuracy of age reporting. More refined methods for the measurement of accuracy of
distributions by single year of age have been devised, but this particular index was selected for
presentation in the Demographic Yearbook for its simplicity and the wide use it has already found in other
sources.
Whipple's Index is obtained by summing the age returns between 23 and 62 years inclusive and
finding what percentage is borne by the sum of the returns of years ending with 5 and 0 to one-fifth of the
total sum. The results would vary between a minimum of 0, if no returns were recorded ending with 0 or
5, and a maximum of 500, if no returns were recorded ending with any digits other than 0 or 5. If there is
no age heaping at ages ending 0 or 5, the Whipple’s index is 100.
9
The index is applicable to all age distributions for which single years are given at least to the age of
62, with the following exceptions: (1) where the data presented are the result of graduation, no
irregularity is scored by Whipple's Index, even though the graduated data may still be affected by
inaccuracies of a different type; and (2) where statistics on age have been derived by reference to the
year of birth, and tendencies to round off the birth year would result in an excessive number of ages
ending in odd numbers, the frequency of age reporting with terminal digits 5 and 0 is not an adequate
measure of their accuracy.
Most recently, the index has been computed for all the single-year age distributions from censuses
held between 1985 and 2003, with the exception of those excluded on the criteria set forth above. Such
data are published in the special issue of the Demographic Yearbook special topic on population
censuses, Volume 1, which is available online at
http://unstats.un.org/unsd/demographic/products/dyb/dybcens.htm.
Although Whipple's Index measures only the effects of preferences for ages ending in 5 and 0, it can
be assumed that such digit preference is usually connected with other sources of inaccuracy in age
statements and the index can be accepted as a fair measure of the general reliability of the age
distribution.

7
3.2 Methods used to indicate quality of published statistics
To the extent possible, efforts have been made to give the reader an indication of reliability of the
statistics published in the Demographic Yearbook. This has been approached in several ways. Any
information regarding a possible under-enumeration or over-enumeration, coming from a postcensal
survey, for example, has been noted in the footnotes to table 3. Any deviation from full national coverage,
as explained in section 2.1 under Geographical Aspects, has also been noted. In addition, national
statistical offices have been asked to evaluate the estimates of total population they submit to the
Statistics Division of the United Nations.
3.2.1 Treatment of time series of population estimates
When a series of mid-year population estimates are presented, the same indication of quality is
shown for the entire series as was determined for the latest estimate. The quality is indicated by the type
face employed.
No attempt has been made to split the series even though it is evident that in cases where the data
are now considered reliable, in earlier years, many may have been considerably less reliable than the
current classification implies. Thus it will be evident that this method overstates the probable reliability of
the time series in many cases. It may also understate the reliability of estimates for years immediately
preceding or following a census enumeration.
3.2.2 Treatment of estimated distributions by age and other demographic characteristics
Estimates of the age-sex distribution of population may be constructed by two major methods: (1) by
applying the specific components of population change to each age-sex group of the population as
enumerated at the time of the census, and (2) by distributing the total estimated for a postcensal year
proportionately according to the age-sex structure at the time of the census. Estimates constructed by the
latter method are not published in the Demographic Yearbook.
Estimated age-sex distributions are categorized as “reliable” or otherwise, according to the method
of construction established for the latest estimate of total mid-year population. Hence, the quality
designation of the total figure, as indicated by the code, is considered to apply also to the whole
distribution by age and sex, and the data are set in italic or roman type, as appropriate, on this basis
alone. Further evaluation of detailed age structure data has not been undertaken to date.
4. VITAL STATISTICS
For purposes of the Demographic Yearbook, vital statistics have been defined as statistics of live
birth, death, foetal death, marriage and divorce.
This volume of the Demographic Yearbook presents tables on fertility, nuptiality and divorce as well
as tables on mortality referring to foetal mortality, infant and maternal mortality and general mortality.
4.1 Sources of variation of data
Most of the vital statistics data published in this Demographic Yearbook come from national civil
registration systems. The completeness and the accuracy of the data that these systems produce vary
from one country or area to another.
The provision for a national civil registration system is not universal, and in some cases, the
registration system covers only certain vital events. For example, in some countries or areas only births
and deaths are registered. There are also differences in the effectiveness with which national laws
pertaining to civil registration operate in the various countries or areas. The manner in which the law is
implemented and the degree to which the public complies with the legislation determine the reliability of
vital statistics obtained from the civil registers.
It should be noted that some statistics on marriage and divorce are obtained from sources other than
civil registers. For example, in some countries or areas, the only source for data on marriages is church
registers. Divorce statistics, on the other hand, are obtained from court records and/or civil registers

8
according to national practice. The actual compilation of these statistics may be the responsibility of the
civil registrar, the national statistical office or other government offices.
Other factors affecting international comparability of vital statistics are much the same as those that
must be considered in evaluating the variations in other population statistics. Differences in statistical
definitions of vital events, differences in geographical and ethnic coverage of the data and diverse
tabulation procedures may also influence comparability.
In addition to vital statistics from civil registers, some vital statistics published in the Demographic
Yearbook are official estimates. These estimates are frequently from population censuses and sample
surveys. As such, their comparability may be affected by the national completeness of reporting in
population censuses and household surveys, whether a de facto or de jure based census, non-sampling
and sampling errors and other sources of bias.

; and Handbook on Civil Registration and Vital Statistics Systems:

. The Handbook on the Collection of Fertility and Mortality Data16
provides information
in collection and evaluation of data on fertility and mortality collected in population censuses and
household surveys. These publications are also available on the website at
http://unstats.un.org/unsd/demographic/standmeth/handbooks/default.htm.
4.1.1 Statistical definition of events
An important source of variation lies in the statistical definition of each vital event. The Demographic
Yearbook attempts to collect data on vital events, using the standard definitions put forth in paragraph 57
of Principles and Recommendations for a Vital Statistics System Revision 2
10
. These are as follows:
LIVE BIRTH is the complete expulsion or extraction from its mother of a product of conception,
irrespective of the duration of pregnancy, which after such separation breathes or shows any other
evidence of life such as beating of the heart, pulsation of the umbilical cord, or definite movement of
voluntary muscles, whether or not the umbilical cord has been cut or the placenta is attached; each
product of such a birth is considered live-born regardless of gestational age.
DEATH is the permanent disappearance of all evidence of life at any time after live birth has taken
place (postnatal cessation of vital functions without capability of resuscitation). This definition therefore
excludes foetal deaths.
FOETAL DEATH is death prior to the complete expulsion or extraction from its mother of a product of
conception, irrespective of the duration of pregnancy; the death is indicated by the fact that after such
separation the foetus does not breathe or show any other evidence of life, such as beating of the heart,
pulsation of the umbilical cord, or definite movement of voluntary muscles. Late foetal deaths are those of
twenty-eight or more completed weeks of gestation. These are synonymous with the events reported
under the pre-1950 term stillbirth17
.
MARRIAGE is an act, ceremony or process by which the legal relationship of husband and wife is
constituted. The legality of the union may be established by civil, religious or other means as recognized
by the laws of each country or area.
DIVORCE is a final legal dissolution of a marriage, that is, that separation of husband and wife which
confers on the parties the right to remarriage under civil, religious and/or other provisions, according to
the laws of each country.
In addition to these internationally recommended definitions, the Demographic Yearbook collects and
presents data on abortions, defined as:

9
ABORTION is defined, with reference to the woman, as any interruption of pregnancy before 28
weeks of gestation with a dead foetus. There are two major categories of abortion: spontaneous and
induced. Induced abortions are those initiated by deliberate action undertaken with the intention of
terminating pregnancy; all other abortions are considered spontaneous.
4.1.2 Problems relating to standard definitions
A basic problem affecting international comparability of vital statistics is deviations from the standard
definitions of vital events. An example of this can be seen in the cases of live births and foetal deaths18
.
In some countries or areas, an infant must survive for at least 24 hours, to be inscribed in the live-birth
register. Infants who die before the expiration of the 24-hour period are classified as late foetal deaths
and, barring special tabulation procedures, they would not be counted either as live births or as deaths.
Similarly, in several other countries or areas, those infants who are born alive but die before registration
of their birth, are also considered late foetal deaths.
Unless special tabulation procedures are adopted in such cases, the live-birth and death statistics
will both be deficient by the number of these infants, while the incidence of late foetal deaths will be
increased by the same amount. Hence the infant mortality rate is underestimated. Although both
components (infant deaths and live births) are deficient by the same absolute amount, the deficiency is
proportionately greater in relation to the infant deaths, causing greater errors in the infant mortality rate
than in the birth rate.
Moreover, the practice exaggerates the late foetal death ratios. Some countries or areas make
provision for correcting this deficiency (at least in the total frequencies) at the tabulation stage. Data for
which the correction has not been made are indicated by a footnote whenever possible.
The definitions used for marriage and divorce also present problems for international comparability.
Unlike birth and death, which are biological events, marriage and divorce are defined only in terms of law
and custom and as such are less amenable to universally applicable statistical definitions. They have
therefore been defined for statistical purposes in general terms referring to the laws of individual
countries or areas. Laws pertaining to marriage and particularly to divorce, vary from one country or area
to another. With respect to marriage, the most widespread requirement relates to the minimum age at
which persons may marry but frequently other requirements are specified.
When known the minimum legal age of men and women at which marriage can occur with or without
parental consent is presented in table 23-1. Laws and regulations relating to the dissolution of marriage
by divorce range from total prohibition, through a wide range of grounds upon which divorces may be
granted, to the granting of divorce in response to a simple statement of desire or intention by husbands.
4.1.3 Fragmentary geographical or ethnic coverage
Ideally, vital statistics for any given country or area should cover the entire geographical area and
include all ethnic groups. Fragmentary coverage is, however, not uncommon. In some countries or areas,
registration is compulsory for only a small part of the population, limited to certain ethnic groups, for
example. In other places there is no national provision for compulsory registration, but only municipal or
state ordinances that do not cover the entire geographical area. Still others have developed a
registration area that comprises only a part of the country or area, the remainder being excluded because
of inaccessibility or for economic and cultural considerations that make regular registration practically
impossible.
4.1.4 Tabulation procedures
4.1.4.1 By place of occurrence
Vital statistics presented at the national level relate to the de facto, that is, the present-in-area
population. Thus, unless otherwise noted, vital statistics for a given country or area cover all the events
that occur within its present boundaries and among all segments of the population therein. They may be
presumed to include events among nomadic tribes and indigenous peoples, and among nationals and
foreigners. When known, deviations from the de facto concept are footnoted.

10
Urban/rural differentials in vital rates for some countries may vary considerably depending on
whether the relevant vital events were tabulated on the basis of place of occurrence or place of usual
residence. For example, if a substantial number of women residing in rural areas near major urban
centres travel to hospitals or maternity homes located in a city to give birth, urban fertility and neo-natal
and infant mortality rates will usually be higher (and the corresponding rural rates will usually be lower) if
the events are tabulated on the basis of place of occurrence rather than on the basis of place of usual
residence. A similar process will affect general mortality differentials if substantial numbers of persons
residing in rural areas use urban health facilities when seriously ill.
4.1.4.2 By date of occurrence versus by date of registration
To the extent possible, the vital statistics presented in the Demographic Yearbook refer to events
that occurred during the specified year, rather than to those that were registered during that period.
However, a considerable number of countries or areas tabulate their vital statistics not by date of
occurrence, but by date of registration. Because such statistics can be misleading, the countries or areas
known to tabulate vital statistics by date of registration are identified in the tables by a plus sign “+”. Since
information on the method of tabulating vital statistics is not available for all countries and areas,
tabulation by date of registration may be more prevalent than the symbols on the vital statistics tables
would indicate.
Because quality of data is inextricably related to the timeliness of registration, this must always be
considered in conjunction with the quality code description in section 4.2.1 below. If registration of births
is complete and timely (code “C”), the ill effects of tabulating by date of registration, are, for all practical
purposes, nullified. Similarly, with respect to death statistics, the effect of tabulating events by date of
registration may be minimized in many countries or areas in which the sanitary code requires that a death
must be registered before a burial permit can be issued, and this regulation tends to make registration
prompt. With respect to foetal death, registration is usually done right away or not at all. Therefore, if
registration is prompt, the difference between statistics tabulated by date of occurrence and those
tabulated by date of registration may be negligible. In many cases, the length of the statutory time period
allowed for registering various vital events plays an important part in determining the effects of tabulation
by date of registration on comparability of data.
With respect to marriage and divorce, the practice of tabulating data by date of registration does not
generally pose serious problems. In many countries or areas marriage is a civil legal contract which, to
establish its legality, must be celebrated before a civil officer. It follows that for these countries or areas
registration would tend to be almost automatic at the time of, or immediately following, the marriage
ceremony. Because the registration of a divorce in many countries or areas is the responsibility solely of
the court or the authority which granted it, and since the registration record in such cases is part of the
records of the court proceedings, it follows that divorces are likely to be registered soon after the decree
is granted.
On the other hand, if registration is not prompt, vital statistics by date of registration will not produce
internationally comparable data. Under the best circumstances, statistics by date of registration will
include primarily events that occurred in the immediately preceding year; in countries or areas with less
developed systems, tabulations will include some events that occurred many years in the past.
Examination of available information reveals that delays of many years are not uncommon for birth
registration, though the majority is recorded between two to four years after birth.
As long as registration is not prompt, statistics by date of registration will not be internationally
comparable either among themselves or with statistics by date of occurrence.
It should also be mentioned that lack of international comparability is not the only limitation
introduced by date-of-registration tabulation. Even within the same country or area, comparability over
time may be lost by the practice of counting registrations rather than occurrences. If the number of
events registered from year to year fluctuates because of ad hoc incentives to stimulate registration, or to
the sudden need, for example, for proof of (unregistered) birth or death to meet certain requirements, vital
statistics tabulated by date of registration are not useful in measuring and analyzing demographic levels
and trends. All they can give is an indication of the fluctuations in the need for a birth, death or marriage
certificate and the work-load of the registrars. Therefore, statistics tabulated by date of registration may
be of very limited use for either national or international studies.

11
4.2 Methods used to indicate quality of published vital statistics
The quality of vital statistics can be assessed in terms of a number of factors. Most fundamental is
the completeness of the civil registration system on which these statistics are based. In some cases, the
incompleteness of the data obtained from civil registration systems is revealed when these events are
used to compute rates. However, this technique applies only where the data are markedly deficient,
where they are tabulated by date of occurrence and where the population base is correctly estimated.
Tabulation by date of registration will often produce rates which appear correct, simply because the
numerator is artificially inflated by the inclusion of delayed registration and, conversely, rates may be of
credible magnitude because the population at risk has been underestimated. Moreover, it should be
remembered that knowledge of what is credible in regard to levels of fertility, mortality and nuptiality is
extremely scant for many parts of the world, and borderline cases, which are the most difficult to
appraise, are frequent.
4.2.1 Quality code for vital statistics from registers.
In the Demographic Yearbook annual “Questionnaire on Vital Statistics” national statistical offices
are asked to provide their own estimates of the completeness of the births, deaths, late foetal deaths,
marriages and divorces recorded in their civil registers.
On the basis of information from the questionnaires, from direct correspondence and from relevant
official publications, it has been possible to classify current national statistics from civil registers of birth,
death, infant death, late foetal death, marriage and divorce into three broad quality categories, as follows:
C: Data estimated to be virtually complete, that is, representing at least 90 per cent of the events
occurring each year.
U: Data estimated to be incomplete, that is representing less than 90 per cent of the events occurring
each year.
|: Data not derived from civil registration systems but considered reliable, such as estimates derived
from projections, other estimation techniques or population and housing censuses.
...: Data for which no specific information is available regarding completeness.
These quality codes appear in the first column of the tables which show total frequencies and crude
rates (or ratios) over a period of years for all tables on live births, late foetal deaths, infant deaths, deaths,
marriages, and divorces. Reliability of maternal mortality statistics is provided by the World Health
Organisation.
The classification of countries and areas in terms of these quality codes may not be uniform.
Nevertheless, it was felt that national statistical offices were in the best position to judge the quality of
their data. It was considered that even the very broad categories that could be established on the basis of
the available information would provide useful indicators of the quality of the vital statistics presented in
this Demographic Yearbook.
In the past, the bases of the national estimates of completeness were usually not available. In
connection with the Demographic Yearbook 1977, countries were asked, for the first time, to provide
some indication of the basis of their completeness estimates. They were requested to indicate whether
the completeness estimates reported for registered live births, deaths, and infant deaths were prepared
on the basis of demographic analysis, dual record checks or some other specified method. Relatively
few countries or areas have responded to this question; therefore, no attempt has been made to revise
the system of quality codes used in connection with the vital statistics data presented in the Demographic
Yearbook. It is hoped that, in the future, more countries will be able to provide this information so that the
system of quality codes used in connection with the vital statistics data presented in the Demographic
Yearbook may be revised.
Among the countries or areas indicating that the registration of live births was estimated to be 90 per
cent or more complete (and hence classified as “C” or “+C” in table 9), the following countries or areas
provided information on the method used to evaluate the completeness estimate:

Among the countries or areas indicating that the registration of late foetal-deaths was estimated to
be 90 per cent or more complete (and hence classified as “C” or “+C” in table 12), the following countries
or areas provided information on the method used to evaluate the completeness estimate:
(a) Demographic analysis -- Argentina, Austria, Bulgaria, Croatia, Estonia, Italy, Latvia, Lithuania,

areas provided information on the method used to evaluate the completeness estimate:
Estonia, Israel, Italy, Latvia, Lithuania, Malta, Mauritius, Republic of Korea, Republic of Moldova,
Romania, Seychelles and Sweden.

4.2.2 Treatment of vital statistics from registers
On the basis of the quality code described above, the vital statistics shown in all tables of the
Demographic Yearbook are treated as either reliable or unreliable. Data coded “C” are considered
reliable and appear in roman type. Data coded “U” or “...” are considered unreliable and appear in italics.
Although the quality code itself appears only in certain tables, the indication of reliability (that is, the use
of italics to indicate unreliable data) is shown in all tables presenting vital statistics data.
In general, the quality code for deaths shown in table 18 is used to determine whether data on
deaths in other tables appear in roman or italic type. However, for some of the maternal deaths data
shown in italics in table 17, the known quality code differs from that ascribed on the basis of the
completeness of registration of the total number of deaths. In cases where the quality code in table 18
does not correspond with the quality level implied by the typeface used in table 17, relevant information
regarding the completeness of maternal mortality is given in a footnote.
It should be noted that the indications of reliability used for infant mortality rates, maternal mortality
ratios and late foetal death ratios (all of which are calculated using the number of live births in the
denominator) are determined on the basis of the quality codes for infant deaths, deaths and late foetal
deaths respectively. To evaluate these rates and ratios more precisely, one would have to take into
account the quality of the live-birth data used in the denominator of these rates and ratios. The quality
codes for live births are shown in table 9 and described more fully in the text of the technical notes for
that table.
4.2.3 Treatment of time series of vital statistics from registers
The quality of a time series of vital statistics is more difficult to determine than the quality of data for
a single year. Since a time series of vital statistics is usually generated only by a system of continuous
civil registration, it was assumed that the quality of the entire series was the same as that for the latest
year's data obtained from the civil register. The entire series is treated as described in section 4.2.2
above. That is, if the quality code for the latest registered data is “C”, the frequencies and rates for earlier
years are also considered reliable and appear in roman type. Conversely, if the latest registered data are
coded as “U” or “...” then data for earlier years are considered unreliable and appear in italics. It is
recognized that this method is not entirely satisfactory because it is known that data from earlier years in
many of the series were considerably less reliable than the current code implies. Efforts are being made
to gradually move away from this method and code the registered data of each year or range of years
separately. Please see for example the technical notes of table 17 in this issue “Maternal deaths and
maternal mortality ratios: 1999-2008”.

14
4.2.4 Treatment of estimated vital statistics
In addition to data from vital registration systems, estimated frequencies and rates of the events,
usually ad hoc official estimates that have been derived either from the results of a sample survey or by
demographic analyses, also appear in the Demographic Yearbook. Estimated frequencies and rates
have been included in the tables because it is assumed that they provide information that is more
accurate than that from existing civil registration systems. By implication, they are assumed to be reliable
and as such they are set in roman type. Estimated frequencies and rates continue to be treated in this
manner even when they are interspersed in a time series with data from civil registers.
In tables showing the quality code, the code applies only to data from civil registers. If a series of
data for a country or area contains both data from a civil register and estimated data, the code applies
only to the registered data; if only estimated data are shown, the symbol “|” is shown.
4.3 Cause of death
World Health Organization (WHO) Member States are bound by the International Nomenclature
Regulations to provide the Organization with cause of death data coded in accordance with the current
revision of the International Statistical Classification of Diseases and Related Health Problems (ICD) as
adopted from time to time by the World Health Assembly19
. The data are collected by the WHO20
using
the ICD. In order to promote international comparability of cause of death statistics, the World Health
Organization organizes and conducts an international conference for the revision of the ICD on a regular
basis in order to ensure that the Classification is kept current with the most recent clinical and statistical
concepts. The data are now usually submitted to WHO at the full four-character level of detail provided
by the ICD and are stored in the WHO Mortality Database at the level of detail as provided by the
country. For earlier versions, however, the data are only available according to the ICD’s list of 150
causes. Data from the WHO Mortality Database are available in electronic format at
http://www3.who.int/whosis/menu.cfm.
Although revisions provide an up-to-date version of the ICD, such revisions create several problems
related to the comparability of cause of death statistics. The first is the lack of comparability over time that
inevitably accompanies the use of a new classification. The second problem affects comparability
between countries and areas because they may adopt a new classification at different times. The more
refined the classification becomes the greater is the need for expert clinical diagnosis of cause of death.
In many countries or areas, few of the deaths occur in the presence of an attendant, who is medically
trained, i.e., most deaths are certified by a lay attendant. Because the ICD contains many diagnoses that
cannot be identified by a non-medical person, the ICD is not always accurately or precisely used, which
affects international comparability particularly between countries and areas where the level of medical
services differ widely.
The chapters of the tenth revision21
, the latest revision of the ICD, consist of an alphanumeric coding
scheme of one letter followed by three numbers at the four-character level. Chapter one contains
infectious and parasitic diseases, chapter two refers to all neoplasms, chapter three to disorders of the
immune mechanism including diseases of the blood and blood-forming organs; and chapter four to
endocrine, nutritional and metabolic diseases. The remaining chapters group diseases according to the
anatomical site affected, except for chapters that refer to mental disorders; complications of pregnancy,
childbirth and the puerperium; congenital malformations; and conditions originating in the perinatal
period. Finally, an entire chapter is devoted to symptoms, signs, and abnormal findings.
4.3.1 Maternal mortality
According to the tenth revision of the ICD, “Maternal death” is defined as the death of a woman while
pregnant or within 42 days of termination of pregnancy, irrespective of the duration and the site of the
pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from
accidental or incidental causes.
“Maternal deaths” should be subdivided into direct and indirect obstetric deaths. Direct obstetric
deaths are those resulting from obstetric complications of the pregnant state (pregnancy, labour and
puerperium), from interventions, omissions, incorrect treatment, or from a chain of events resulting from
any of the above. Indirect obstetric deaths are those resulting from previous existing disease or disease
that developed during pregnancy and which was not due to direct obstetric causes, but which was
aggravated by physiologic effects of pregnancy.

15
While the denominator for the maternal mortality ratio theoretically should be the number of pregnant
women, it is impossible to determine the number of pregnant women. A further recommendation by the
tenth revision is therefore that maternal mortality ratios be expressed per 100,000 live births or per
100,000 total births (live births and foetal deaths)22
. The maternal mortality ratio calculated here is
expressed per 100,000 live births. Although live births do not represent an unbiased estimate of pregnant
women, this figure is more reliable than other estimates, in particular, live births are more accurately
registered than live births plus foetal deaths.

Alternatively, if a population register is used, completed ages are calculated by subtracting the date of birth of individuals listed in
the register from a reference date to which the age data pertain.
7
A source of non-comparability may result from differences in the method of reckoning age, for example, the Western versus the
Eastern or, as it is usually known, the English versus the Chinese system. By the latter, a child is considered one year old at birth
and advances an additional year at each Chinese New Year. The effect of this system is most obvious at the beginning of the age
span, where the frequencies in the under-one-year category are markedly understated. The effect on higher age groups is not so
apparent. Distributions constructed on this basis are often adjusted before publication, but the possibility of such aberrations
should not be excluded when census data by age are compared.

INTRODUCTION
L'Annuaire démographique est un recueil de statistiques démographiques internationales qui est établi
par la Division de statistique du Département des affaires économiques et sociales de l'Organisation des
Nations Unies. Il fait partie d'un ensemble de publications complémentaires publiées par l'Organisation des
Nations Unies et les institutions spécialisées, qui ont pour objet de fournir des statistiques aux
démographes, aux économistes, aux spécialistes de la santé publique et aux sociologues. Grâce à la
coopération des services nationaux de statistique, il a été possible de faire figurer dans la présente édition
de l’Annuaire démographique les statistiques officielles disponibles pour plus de 230 pays ou zones du
monde entier.
L'Annuaire démographique 2009-2010 est la soixante-et-unième édition d'une série que publie l'ONU
depuis 1948. Le présent volume comprend un aperçu mondial des statistiques démographiques de base et
des tableaux qui regroupent des statistiques sur la dimension, la répartition et les tendances de la
population, la natalité, la mortalité fœtale, la mortalité infantile et la mortalité liée à la maternité, la mortalité
générale, la nuptialité et la divortialité. Des données classées selon le lieu de résidence (zone urbaine ou
rurale) sont présentées dans un grand nombre de tableaux. En outre, l'Annuaire démographique contient
des notes techniques, un tableau synoptique, un index historique et une liste des éditions de l'Annuaire
démographique publiées jusqu'à présent. Cette édition de l'Annuaire démographique contient les données
disponibles couvrant les années de référence 2009 et 2010. Dans les tableaux des statistiques de la
population et de l'état civil où figurent des séries chronologiques, sont présentées les données disponibles
pour les années de référence 2009 et 2010. Dans les tableaux statistiques détaillés de population et d’état
civil qui contiennent les dernières données disponibles pendant 2000-2009, des tableaux supplémentaires
sont mis à disposition pour les données disponibles de l’année de référence 2010.
Les notes techniques sur les tableaux statistiques sont destinées à aider le lecteur. Le tableau A, qui
correspond au tableau synoptique, donne un aperçu de l''exhaustivité des données publiées dans la
présente édition de l’Annuaire démographique. Un index cumulatif donne des renseignements sur les
matières traitées dans chacune des 61 éditions et sur les années sur lesquelles portent les données. Les
numéros de vente des éditions antérieures et une liste des sujets spéciaux traités dans les différentes
éditions sont indiqués aux pages iii et iv.
Jusqu'à la 48
ème
édition (1996), chaque édition se composait de deux parties : les tableaux de caractère
général et ceux sur des sujets spéciaux1
. À partir de 49
ème
édition (1997), les tableaux sur les sujets
spéciaux ont été publiés dans un format numérique en tant que suppléments à l'Annuaire démographique.
Deux CD-ROM ont été produits : l'Annuaire démographique : Supplément historique, qui présente un grand
nombre de statistiques démographiques pour la période allant de 1948 à 1997, et l'Annuaire
démographique : Statistiques de la natalité, qui contient des tableaux détaillés sur la natalité pour la période
allant de 1980 à 1998. En plus, trois volumes concernant l’Annuaire démographique consacrés à des
thèmes de recensement spéciaux sont publiés en ligne à l'adresse suivante :
http://unstats.un.org/unsd/demographic/products/dyb/dybcens.htm. Les sujets des statistiques de ces
volumes sont : Caractéristiques essentielles de la population, caractéristiques de l’enseignement et des
origines ethniques et culturelles, et les caractéristiques des migrations internationales. Les actuelles bases
de données sur les thèmes du recensement de l’Annuaire démographique pour les années de référence
entre 1995 et aujourd’hui sont mises à disposition sur
http://unstats.un.org/unsd/demographic/products/dyb/dybcensusdata.htm. Ces bases de données
comprennent des données sur la population selon les principales caractéristiques démographiques,
scolaires, ethnoculturelles et économiques, les caractéristiques des ménages ainsi que des données sur
les étrangers dans le pays ou les personnes nées à l’étranger.
Les statistiques sur la population ne sont pas disponibles pour tous les pays et zones pour plusieurs
raisons. Deux annexes sont présentées afin d'offrir des estimations sur la population en milieu d'année et un
aperçu des statistiques de l'état civil pour chaque pays ou zone. La première porte sur des estimations
concernant la population pour la période 2001-2010. La seconde présente les estimations des variantes
moyennes concernant les taux bruts de natalité et de mortalité, la mortalité infantile, les indicateurs
synthétiques de fécondité et l'espérance de vie à la naissance pour la période 2005-2010. Ces données ont
été établies par la Division de la population de l'ONU et publiées dans World Population Prospects - The
2010 Revision2
.
Les statistiques démographiques figurant dans la présente édition de l'Annuaire démographique sont
disponibles en ligne sur les pages Web consacrées à l'Annuaire démographique :

http://unstats.un.org/unsd/demographic/products/dyb/dyb2009-2010.htm. On trouvera également des
renseignements sur le programme de collecte et de diffusion des données de la Division de statistique sur le
même site. Il est possible de se procurer d'autres données en contactant la Division de statistique de
l'Organisation des Nations Unies à l'adresse suivante : demostat@un.org.
NOTES TECHNIQUES SUR LES TABLEAUX STATISTIQUES
1. REMARQUES D'ORDRE GÉNÉRAL
1.1 Notes techniques
Les notes techniques ont pour but de donner au lecteur des informations pertinentes en lien avec les
tableaux statistiques. Les renseignements qui concernent l'Annuaire démographique en général sont
présentés dans des sections portant sur diverses considérations géographiques, sur la population et sur les
statistiques de natalité et de mortalité. Les tableaux sont ensuite commentés séparément et l'on trouvera
pour chacun une description des variables et des observations sur la fiabilité et les lacunes des données
ainsi que sur les pays et zones visés et sur les données publiées antérieurement. Des détails sont
également donnés, le cas échéant, sur le mode de calcul des taux, quotients et pourcentages.
1.2 Tableaux
Dans la mesure du possible, la numérotation des tableaux dans les éditions successives de l'Annuaire
démographique est préservée. Comme la numérotation des tableaux ne correspond pas exactement à celle
des éditions précédentes, il est recommandé de se reporter à l'index qui figure à la fin du présent ouvrage
pour trouver les données publiées dans les précédentes éditions.
1.3 Origine des données
Sauf indication contraire, les statistiques présentées dans l'Annuaire démographique sont des données
nationales fournies par les organismes de statistique officiels. Elles sont recueillies essentiellement au
moyen de questionnaires qui sont envoyés tous les ans à plus de 230 services nationaux de statistique et
autres services gouvernementaux compétents. Les données communiquées en réponse à ces
questionnaires sont complétées, dans toute la mesure possible, par des données tirées de publications
nationales officielles et des sites web d'organismes officiels et des renseignements communiqués par les
services nationaux de statistique à la demande de l'ONU. Pour que les données soient comparables, les
taux, rapports et pourcentages ont été calculés par la Division de statistique de l'ONU, à l'exception des
paramètres des tables de mortalité et des indicateurs synthétiques de fécondité ainsi que des taux bruts de
natalité et de mortalité pour certains pays et zones, qui ont été dûment signalés en note. Les méthodes
suivies par la Division pour le calcul des taux et rapports sont décrites dans les notes techniques relatives à
chaque tableau. Les chiffres de population utilisés pour ces calculs sont ceux qui figurent dans la présente
édition de l'Annuaire démographique ou qui ont paru dans des éditions antérieures.
Chaque fois que l'on constatera des différences entre les données du présent volume et celles des
éditions antérieures de l'Annuaire démographique, ou de certaines publications apparentées, on pourra en
conclure que les statistiques publiées cette année sont des chiffres révisés communiqués à la Division de
statistique avant juin 2011.
2. CONSIDÉRATIONS GÉOGRAPHIQUES
2.1 Portée
Des données sont présentées sur tous les pays ou zones qui en ont communiquées. Le tableau 3, le
plus complet, contient des données sur la population et la superficie de chaque pays ou zone ayant une
population d'au moins 50 habitants. Ces pays ou zones ne figurent pas tous dans les tableaux qui suivent.
Dans bien des cas, les données requises pour un tableau particulier n'étaient pas disponibles. En général,
les pays ou zones qui peuvent fournir des données sont d'autant moins nombreux que les données
demandées sont plus détaillées.
17

De plus les taux et rapports ne sont présentés que pour les pays ou zones ayant communiqué des
chiffres correspondant à un nombre minimal de faits considérés. Les minimums sont indiqués dans les
notes techniques relatives à chacun des tableaux.
À l'exception des données récapitulatives présentées dans les tableaux 1 et 2 pour l'ensemble du
monde et les grandes zones et régions et des données relatives aux capitales et aux villes de
100 000 habitants ou plus dans le tableau 8, toutes les données se rapportent aux pays. Le nombre de pays
sur lequel porte chacun des tableaux est indiqué dans le tableau A.
2.2 Composition territoriale
Autant que possible, toutes les données, y compris les séries chronologiques, se rapportent au territoire
de 2010. Les exceptions à cette règle sont signalées en note à la fin des tableaux. Des clarifications
importantes sont présentées ci-dessous.
Les données relatives au Danemark ne comprennent pas les Iles Féroé et le Gröenland, qui font l'objet
de rubriques distinctes.
Les données relatives à la Finlande comprennent les Îles d'Åland, sauf indication contraire en note de
bas de page.
Les données relatives à la France ne comprennent pas les départements d'outre mer, c'est- à -dire la
Guyane française, Guadeloupe, la Martinique et La Réunion, qui font l'objet de rubriques distinctes, sauf
indication contraire en note de bas de page.
Les données relatives à la Norvège ne comprennent pas Svalbard et Jan Mayen qui font l'objet de
rubriques distinctes, si disponible.
Les données relatives au Soudan comprennent le Soudan du Sud. La République du Sud-Soudan a
officiellement fait sécession du Soudan, le 9 Juillet 2011. Cependant cette édition de l'Annuaire
démographique contient les données des années de référence antérieures à 2010.
Les données relatives au Royaume-Uni de Grande-Bretagne et d'Irlande du Nord ne comprennent pas
la Guernesey, l'île de Man et Jersey, qui font l'objet de rubriques distinctes.
Les données relatives au Sahara Occidental comprennent la région septentrionale (ancien Saguia-el-
Hamra) et la région méridionale (ancien Rio de Oro).
2.3 Nomenclature
En règle générale, pour gagner de la place, on a jugé commode de désigner dans les tableaux les pays
ou zones par les noms abrégés couramment utilisés par l'Organisation des Nations Unies
3
, les désignations
complètes n'étant utilisées que lorsqu'il n'existait pas de forme abrégée. La liste des désignations des pays
ou zones est disponible à l'adresse suivante : http://unstats.un.org/unsd/methods/m49/m49alphaf.htm.
2.3.1 Ordre de présentation
Les pays ou zones sont classés dans l'ordre alphabétique anglais et regroupés par continent comme ci-
après : Afrique, Amérique du Nord, Amérique du Sud, Asie, Europe et Océanie.
Les appellations employées dans la présente édition et la présentation des données qui y figurent n'ont
d'autre objet que de donner un cadre géographique commode aux séries statistiques. La même observation
vaut pour toutes les notes et précisions concernant les unités géographiques pour lesquelles des données
sont présentées.
