About the Census
The census is a count of everyone living in the United States and is conducted every 10 years as mandated by the United States Constitution, Article 1, Section 2. The first census was taken in 1790, by the U.S. marshals on horseback and counted 3.9 million people. The most recent census was taken in 2000 and counted more than 281 million people. The census is the foundation for measuring the nation’s population and includes all persons dwelling in U.S. residential structures, including citizens and non-citizens.
