The U.S.Census Bureau was established as a permanent office by act of March 6, 1902 (32 Stat. 51). The major functions of the Census Bureau are authorized by the Constitution, which provides that a census of population shall be taken every 10 years, and by laws codified as title 13 of the United States Code. The law also provides that the information collected by the Census Bureau from individual persons, households, or establishments be kept strictly confidential and be used only for statistical purposes. The Census Bureau is responsible for the the decennial censuses of population and housing; the quinquennial censuses of State and local governments, manufacturers, mineral industries, distributive trades, construction industries, and transportation; current surveys that provide information on many of the subjects covered in the censuses at monthly, quarterly, annual, or other intervals; the compilation of current statistics on U.S. foreign trade, including data on imports, exports, and shipping; special censuses at the request and expense of State and local government units; publication of estimates and projections of the population; publication of current data on population and housing characteristics; and current reports on manufacturing, retail and wholesale trade, services, construction, imports and exports, State and local government finances and employment, and other subjects.
