A standardized system of numeric coding for geographic areas originally issued by the National Institute of Standards and Technology (NIST), an agency of the U.S. Department of Commerce. FIPS codes are assigned for a variety of geographic entities, including American Indian and Alaska Native Areas, Hawaiian homelands, congressional districts, counties, county subdivisions, metropolitan areas, places, and states. The purpose of using FIPS codes is to improve data use and avoid unnecessary duplication and incompatibility in the collection, processing, and dissemination of data. NIST discontinued FIPS codes in 2005. Still, the Census Bureau continues to maintain and issue codes for the geographic entities, calling them Federal Information Processing Series (FIPS) codes, using the same acronym.
