About

The Census is a head count of everyone residing in the United States. It has been mandated by the U.S. Constitution (Article 1, Section 2) since 1790 and it occurs every 10 years. The Census counts people of all ages, race, ethnic groups, citizens and noncitizens. Population totals from the decennial Census determine the number of seats each state has in the House of Representatives; the totals are also used to redraw legislative districts. The Census is also used to help determine the appropriation of federally funded programs. Census data is safe. The constitution protects Census information from being shared with the Department of Homeland Security or any other federal agency.
