The Bureau of the Census prepares base maps that are used in the planning and conduct of its various censuses and surveys. The Census Bureau also prepares for publication detailed maps showing States and State equivalents (i.e., the District of Columbia, Puerto Rico, and the several U.S. territories and possessions), counties and county equivalents, Congressional districts, county subdivisions, places, American Indian reservations, urbanized areas, metropolitan areas, census tracts, block-numbered areas, blocks, and other geographic units. Some of these maps show roads and other physical features, others show only area outlines and related identifiers. The Census Bureau also issues U.S. maps showing boundaries (e.g., States and metropolitan areas) and sometimes data set of maps. For the 2000 Decennial Census, an automated geographic data base, called the TIGER system was used to generate maps, geographic base files, and other geographic products. In addition, the Census Bureau, in conjunction with State and local governments, maintains records of changes in legally-defined areas, delimits the boundaries of most statistical areas, and develops geographic code systems that are used in the electronic data processing of the information.
