Every 10 years, the U.S. Census Bureau conducts the federal national census (U.S. Constitution, Article I, sec. 2). Census figures are essential in determining how much federal funding a state receives, as well as how many U.S. Representatives represent each state in Congress.

In between decennial censuses, the U.S. Census Bureau issues QuickFacts, which shows yearly statistics.
