Combined Statistical Area

The United States Office of Management and Budget (OMB) defines micropolitan and metropolitan statistical areas. Currently defined metropolitan and micropolitan statistical areas are based on application of the 2000 standards (which appeared in the Federal Register on December 27 2000) to Census 2000 data, as updated by application of those standards to more recent Census Bureau population estimates. The current definition is as of November 2004.

Metropolitan and micropolitan statistical areas consist of one or more counties. The OMB defines a conceptually similar set of areas in New England using cities and towns as geographic building blocks, referred to as New England city and town areas (NECTAs).

If specified criteria are met, adjacent metropolitan and micropolitan statistical areas, in various combinations, may become the components of a new set of areas called combined statistical areas (CSAs). Using Census Bureau data the OMB compiles lists of CSAs. The geographic components of combined New England city and town areas are individual metropolitan and micropolitan NECTAs, in various combinations. The areas that combine retain their own designations as metropolitan or micropolitan statistical areas (or NECTAs) within the larger combined statistical area (or combined NECTA).
