New England City and Town Areas (NECTAs) are an alternative set of geographic entities, similar in concept to the county-based CBSAs, that OMB defines in New England based on county subdivisions—usually cities and towns.  NECTAs receive a category in a manner similar to CBSAs and are referred to as metropolitan NECTAs or micropolitan NECTAs.
