About the Census

The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions in federal funds to local communities.  The 2010 Census represented the most massive participation movement ever witnessed in our country.  Census 2020 is nearing.

The Census Bureau's mission is to serve as the leading source of quality data about the nation's people and economy.
