Every 10 years, the federal government conducts a population count of everyone in the United States. Data from the census provides the basis for distributing more than $675 billion in federal funds annually to communities across the country to support vital programs—impacting housing, education, transportation, employment, health care, and public policy. They also are used to redraw the boundaries of congressional and state legislative districts and accurately determine the number of congressional seats each state has in the U.S. House of Representatives.
