The Census
One tool that helps people chart population growth and decline in the United States is the census. A census is a measure of people living in a certain area. The U.S. census is the count of how many people live in the United States and is conducted every 10 years. A list of questions called a survey is sent to every home. If the survey isn’t returned, a census worker visits the home. The worker helps the people living there to fill out the survey. The survey asks who is living at the address. It also asks for important information about the people, such as their age and what they do for work. The U.S. Constitution requires a census. The House of Representatives is based on the number of people in a district or region. Regions grow or shrink in population. This causes the number of representatives to be adjusted. Census information is made public. People can use census details in many ways. Businesses can determine if they should expand or downsize. Social scientists can use the information to learn about people and communities. Individuals can use census data to find ancestors and family members. Population information is available from every census since 1790. The data is considered a primary source for research.
