Chapter 3: The World's People  "The World Population Clock"

Introduction In this chapter you have read about the world's rapidly growing population. As the population increases so does the need for food, health care, education, etc. Demographers study the characteristics of population. The U.S. Constitution requires the government to make a count of the population of the United States every ten years. Population experts at the U.S. Census Bureau compile the results of these population studies and others from around the world and throughout world history. These numbers are used to make decisions on taxes, spending, and other government policies. Destination Title: U.S. Census Bureau Note: Clicking on the link above will launch a new browser window.
