Demography is the study of the size, composition, and distribution of the population. Population growth is the result of fertility (births), mortality (deaths), and migration (the movement of people from one geographic area to another for the purpose of changing residency).
Kendall Text is lacking in terms of the information about and the manner in which she presents the populationStatistics about the United States of America. On pg. 334 she makes a passing reference to the black population; saying it represents 13% of the total U.S. Population; Moreover, she in turn cites on pg. 339, the Latino population consists of 42 million
n addition to growth rates, another way to look at population growth is to consider annual changes in the total population. The annual increase in world population peaked at about 88 million in the late 1980s. The peak occurred then, even though annual growth rates were past their peak in the late 1960s, because the world population was higher in the 1980s than in the 1960s.
Population growth did not occur in a vacuum. It was closely associated with major changes in technology and social organization: essentially with the transformation to fossil fuels and the rise of urban industrial society
Thomas Robert Mathus, early 1800 economist and religious scholar was the forerunner to the field of demography.Undertook a systemic study of the peffects of population; focusing on the role of the Industrial Revolution in England; 1798. He argued that the power of population is infinitely greater than the power of the erth to produce subsistence (food) for man.
To understand this overall pattern of population growth, it is useful to review a basic condition of demographic history, known as the demographic transition: the change of a population from high birth and death rates to low birth and death rates. It is a simple definition, but an exceedingly powerful one, for it shows clearly a major transformation of human reproduction.

What is the Census?<br />· The census is a count of everyone living in the United States every 10 years. <br />· The census is mandated by the U.S. Constitution. <br />· The next census is in 2010. <br />· Your participation in the census is required by law. <br />· It takes less than 10 minutes to complete. <br />· Federal law protects the personal information you share during the census. <br /><ul><li>Census data are used to distribute Congressional seats to states, to make
decisions about what community services to provide, and to distribute $300 billion in federal funds to local, state and tribal governments each year</li></ul>http://2010.census.gov/2010census/<br />

The Pew Research Center (www.pewresearch.org) is a nonpartisan "fact tank" that provides information on the issues, attitudes and trends shaping America and the world. It does not take positions on policy issues. Its work is carried out by eight projects, among them the Pew Hispanic Center and the Social & Demographic Trends project, which together produced this report.

Population<br />World’s population of 6.4 billion in 2005 is increasing by more than 76 million people per year.<br />Between 2000 and 2030, almost all of the world’s population growth will be in low-income countries.<br />
Projected world population figure, year 2040<br />
Cities <br />Only about 3% of the world’s population lived in cities 200 years ago, as compared with almost 50% today.<br />Current estimates suggest that two out of every three people around the world will live in urban areas by 2050. <br />
Malthusian Perspective<br /><ul><li>If left unchecked, the population would exceed the available food supply.
Population would increase in a geometric progression (2, 4, 8, …) .
The food supply would increase by an arithmetic progression (1, 2, 3, 4 . . .).</li></li></ul><li>Malthusian Perspective<br />Positive Checks:<br /> - center on mortality;<br /> - famine, disease and war<br />Preventative Checks:<br /> - limits to fertility;<br /> - immigration restrictions.<br />
