Background

The United States census counts the nation’s population and gathers information on certain characteristics (e.g., age, gender, ethnicity, etc.) of people residing in the country. It takes place every 10 years, in years ending in zero. Since 1930, Census Day has been April 1st.

A national census is mandated by Article I Section 2 of the U.S. Constitution to allocate seats in the House of Representatives and calculate direct taxes. The first national census took place in 1790 with six questions, but the type and number of questions asked on subsequent censuses have varied. The process of gathering responses for the census–and for analyzing the data–has also changed over time. Before 1970, census takers went door-to-door to collect information on the population; but after 1970, responses were collected primarily by mail.

Although the census aims to gather accurate data about people living in the United States, there are concerns about the underreporting and undercounting of some communities, such as minorities. The 2020 census is the 24th national census.
