Decennial Census

Every 10 years since 1790, the U.S. Census Bureau conducts a census to determine the number of people living in the United States. The data collected by the decennial census has several high profile applications: they are used to reapportion seats in the House of Representatives, to realign congressional districts, to redistrict within each state, and as a factor in the formulas that distribute hundreds of billions of dollars in federal funds each year. It is a count of everyone residing in the United States on the census date of April 1st. The 2020 Census was the last decennial census taken.
