From the US Census website:

Most people know that the U.S. Census Bureau measures the nation’s population once every 10 years. But fewer know that every five years, it conducts another important survey that measures the nation’s businesses to give us a comprehensive measure of U.S. economic activity across more than 21,000 geographic areas. The data produced from the economic census guides business decisions that affect you and the community you live in.
