United States Census Bureau is part of the United States Department of Commerce and its director is appointed by the President of the United States of America.
United States Census Bureau's primary mission is conducting the U.S. Census every ten years, which allocates the seats of the United States House of Representatives to the states based on their population.
United States Census Bureau's various censuses and surveys help allocate over $400 billion in federal funds every year and it helps states, local communities, and businesses make 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 dozens of other censuses and surveys, including the American Community Survey, the U.S. Economic Census, and the Current Population Survey. Furthermore, economic and foreign trade indicators released by the United States federal government typically contain data produced by the Census Bureau.
The Article One of the United States Constitution (section II) directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the United States House of Representatives and, by extension, in the Electoral College. The Census Bureau now conducts a full population count every 10 years in years ending with a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population estimates and projections
