About NAICS & SIC Codes

North American Industry Classification System (NAICS) and Standard Industrial Classification (SIC) codes were created by the United States government to group similar companies into industries in order to collect, analyze, and share statistical data across various agencies. Just as library materials are grouped by Dewey Decimal or Library of Congress call numbers, companies are grouped into industries by SIC and NAICS codes. Many business databases allow searching by code which may help users find competitors and other industry information that would not be found in a keyword search.

About CSAs, Metro and Micro CBSAs, CCDs/MCDs, & DMA Regions

Geographic areas defined by the U.S. Office of Management and Budget (OMB) are used by the Census Bureau and other organizations.

  • Combined Statistical Areas (CSAs) consist of two or more adjacent CBSAs that have substantial employment interchange.
    • Core Based Statistical Areas (CBSAs) consist of the county or counties or equivalent entities associated with at least one core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties with the counties associated with the core.
      • Metropolitan SAs are at least one urbanized area that has a population of at least 50,000.
      • Micropolitan SAs are at least one urban cluster that has a population of at least 10,000 but less than 50,000.
    • Census County Divisions (CCDs) are areas delineated by the Census Bureau in cooperation with state, tribal, and local officials for statistical purposes. CCDs have no legal function and are not governmental units.
    • Minor Civil Divisions (MCDs) are the primary governmental or administrative divisions of a county in many states (parishes in Louisiana) and the county equivalents in Puerto Rico and the Island Areas. MCDs represent many different kinds of legal entities with a wide variety of governmental and/or administrative functions.
  • Designated Market Areas (DMA) Regions are the geographic areas in the United States in which local television viewing is measured by Nielsen, an American information, data, and measurement firm.
