United States Census Bureau

The Census Bureau's primary mission is conducting the U.S. census every ten years, which allocates the seats of the U.S. House of Representatives to the states based on their population. The bureau's various censuses and surveys help allocate over $675 billion in federal funds every year and it assists states, local communities, and businesses in making informed decisions. The information provided by the census informs decisions on where to build and maintain schools, hospitals, transportation infrastructure, and police and fire departments.
In addition to the decennial census, the Census Bureau continually conducts over 130 surveys and programs a year, including the American Community Survey, the U.S. Economic Census, and the Current Population Survey.USCB DOC-D1026 QVC Manual 01/03/09 The U.S. Economic Census occurs every five years and reports on American Business and the American economy in order to plan business decisions.
