Ch 15 - Population

1. 1. What is the census?
Chapter 15 Section 1
An official count of all people and their place of residence, established by
the Constitution and taken every 10 years, to determine how many
Representatives each state receives
Researchers who study population growth and density are called
demographers.
2. Name and describe two ways the Census Bureau tabulates and presents data.
Urban populations – groups of people of 2,500 or more or people living in
incorporated towns
Rural populations – groups of people living in sparsely inhabited areas

2. 3. List three significant changes in the population of the United States since colonial
times
a. 1790 to 1860 (~Revolutionary War to Civil War): population was increasing
at a rate of 3% per year, average household had 5.8 people
b. 1860-1945 (Civil War to World War II): rate of growth decreased to 2.23%
and eventually 1.38%
c. Current day: Population growth is under 1% per year, average 2.65 people
per household
More people living alone than ever before

3. 4. What are three major factors affecting the growth of population in the United
States?
a. Fertility rate: number of births per woman in her lifetime
b. Life expectancy: average remaining life span of people who reach a
certain age

c. Net Immigration: net change of people coming into and going out of the
country

4. 5. How will the baby boomers affect the dependency ratio?
Baby Boom – period after World War II between 1946 and 1964 where births
spiked
Dependency Ratio – the number of children and elderly (who are dependent
on others) for every 100 adults between the working ages of 18 and 65
The large number of baby boomers will soon be considered elderly (65+)
and thus increase the dependency ratio greatly.
What year will the earliest-born baby boomers start hitting age 65? What
about the latest-born baby boomers?
2011-2029, the years the baby boomers start entering retirement…spooky!

5. Chapter 15 Section 2
1. a. What is a good measure of economic growth in the short run?
For 1-5 years, real GDP (i.e., GDP adjusted for inflation)
b. What is a good measure of economic growth in the long run?
For more than 5 years, real GDP per capita to account for population increases
and decreases

8. 2. What are five ways in which economic growth benefits the United States?
Standard of Living – quality of life based on the possession of necessities
and luxuries that make life easier
Government Spending – adds to the number and quality of public services
Domestic Problems – creates more jobs and income, which can help with
poverty, medical care, and inequality of opportunity
Helping Other Nations – purchasing goods and services from other
countries can be mutually beneficial
Global Role Model – many developing countries do not have established
political and economic ideas

9. 3. What are four factors that influence economic growth?
Land – natural resources such as minerals, clean air, water, forests, and fertile
land which are abundant in the U.S., but not countries like Japan and Great
Britain
Capital – tools, equipment, and factories used in the production of goods
and services, more capital -> more goods and services -> more growth
Labor – a skilled and growing work force tied to a country’s population
foreign workers and retirees returning to the work force are options
for countries that face a population/labor shortage
Entrepreneurs – the key to economic growth, entrepreneurs innovate, act as
agents of change, and take risks that promote economic progress

10. 4. What must the United States do to keep its land resources from dwindling?
Establish regulations to improve conservation so that natural resources are
not used faster than they can be replenished (e.g., cutting down trees)
5. How does declining productivity hurt the American economy?
Labor productivity – the rate of economic growth per unit of labor output
(i.e., how efficiently are goods and services produced)
Declining productivity means possibly losing a competitive edge compared
to other countries, which means fewer jobs, lower profits, higher prices, and
underemployment (e.g., an engineer having to work at McDonald’s due to a
lack of engineering work)

11. Chapter 15 Section 3
1. What is a business cycle?
The cycle of ups and downs of the real GDP
2. What are the two phases of the business cycle?
a. Recession – a decline in real GDP for a period of at least 6 months
b. Expansion – a period of recovery from a recession, real GDP increases
3. a. At what point in the business cycle does a recession begin?
b. At what point in the business cycle does a recession end?
Peak
Trough
4. What term refers to a very severe recession? Depression

12. 5. What four factors worked together to cause the Great Depression?
Great Depression: Started with Stock Market crash of 1929, between 1929
and 1933, GDP fell from $103bb to $55bb (roughly half), unemployment
went from 1.6m people to 12.8m, 25% of workers were unemployed,
average wages went from 55cents/hr to 5cents/hr, thousands of banks failed
(depositors lost everything since no FDIC), money supply fell by 33% which
forced towns and counties to print their own money (depression scrip)
a. Distribution of income: people were either very poor or very rich, the poor
couldn’t afford to spend anything while the rich spent their money
unproductively (e.g., betting on the stock market)
b. Credit too plentiful: many people borrowed extensively, which left them
with absolutely nothing when the economy took a turn for the worse
c. Foreign loans: Without loans, foreign countries could not afford U.S.
goods -> lower demand -> lower production -> fewer jobs
d. High tariffs: Taxes on imported goods made countries less willing to sell
to the U.S.
