Who told you this stuff?

The U.S. Census Bureau takes a census of the population every 10 years, and censuses of economic activity and governments every five years. And every year, the Census Bureau conducts more than 100 other surveys. Data on this page come from the 2010 Census, the American Community Survey, and County Business Patterns.

How are these data collected?

The U.S. Census Bureau sends questionnaires in the mail or contacts businesses and households to participate in its surveys.

* State symbol information was obtained from various non-Census Bureau resources including state web sites, educational web sites, and commercial entities.
