|Metropolitan Statistical Areas (MSAs)||MSAs consist of a core area with a large population and adjacent communities having a high degree of social and economic integration with the core. They are defined by the US Office of Management and Budget (OMB). MSAs are generally counties (cities and towns in New England) containing at least one city or urbanized area with a population of at least 50,000 and a total metropolitan population of at least 100,000 (75,000 in New England).|
MSAs of one million or more population may be recognized as Consolidated Metropolitan Statistical Areas (CMSAs). Primary Metropolitan Statistical Areas (PSMAs) are component areas within MSAs. New England County Metropolitan Areas (NECMAs) are the county based metropolitan alternative of the New England states for the city and town based MSAs and CMSAs.
