United States® Census 2020

About the 2020 Census

The U.S. Constitution mandates a census of the population every 10 years. The 2020 Census will count everyone who lives in the U.S. as of April 1, 2020 (Census Day). Census statistics are used to determine the number of seats each state holds in the U.S. House of Representatives and to inform how billions of dollars in federal funds will be allocated by state, local, and federal lawmakers every year for the next 10 years. Beginning in mid-March, households can respond online, by phone, or by mail.
