New England city and town area
A New England city and town area (NECTA) is a geographic and statistical entity defined by the U.S. federal government for use in the six-state New England region of the United States. NECTAs are analogous to metropolitan statistical areas and micropolitan statistical areas and are defined using the same criteria, except that they are defined on the basis of New England towns instead of entire counties. NECTAs are classified as either metropolitan or micropolitan NECTAs. A micropolitan NECTA has an urban core with a population of at least 10,000 but less than 50,000 , whereas a metropolitan NECTA has an urban core with a population of at least 50,000. In New England, towns (which are classified by the United States Census Bureau as minor civil divisions) are a much more important level of government than counties. Because towns are smaller than counties, a NECTA usually provides a much closer approximation to the real metropolitan area than a metropolitan statistical area does. Large NECTAs (with population greater than 2.5 million) may be subdivided into smaller groupings known as NECTA Divisions. Adjacent NECTAs that have a high degree of employment interchange may also be combined to  form Combined NECTAS (or CNECTAs). NECTAs that are part of a CNECTA retain their separate identities.
