Article 1, Section 2, of the U.S. Constitution, mandates that the country conduct a count of its population once every 10 years. The 2020 Census will mark the 24th time that the country has counted its population since 1790. The Census is conducted by the U.S. Census Bureau, a nonpartisan government agency. The 2020 Census counts every person living in the 50 states, District of Columbia, and five U.S. territories.
Participating in the census is required by law, even if you recently completed another survey from the Census Bureau.
