About the Census
For more than 200 years, the U.S. Census Bureau has conducted a census every ten years to count every resident in the nation. It is a constitutional requirement to determine the number of seats each state has in the U.S. House of Representatives as well as to distribute billions of dollars in federal funds to local communities.
Census data are also used to determine the boundaries of congressional, state and local political districts. Census demographic data provide information for use in all types of studies, serving as a benchmark for surveys, estimates and forecasts.
