2010 U.S. Census Data: Main Website


The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions in federal funds to local communities.

  • The Decennial Census collects data every 10 years about households, income, education, homeownership, and more for the United States, Puerto Rico, and the Island Areas. 
  • The American Community Survey is a nationwide survey designed to provide communities a fresh look at how they are changing.
  • The Puerto Rico Community Survey is the equivalent of the American Community Survey for Puerto Rico. 
  • The Economic Census profiles the U.S. economy every 5 years, from the national to the local level and by detailed industry and business classification.

In a search engine, type the name of any state followed by the words "state data" or "state demographics" (example: Tennessee state data).
