The Office of Management and Budget (OMB) defines the Metropolitan Statistical Areas (MSAs) as having at least one urbanized area of 50,000 or more population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties. Micropolitan Statistical Areas are defined as having at least one urban cluster of at least 10,000 but less than 50,000 population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties. The MSA codes are 5 digits in length, falling within the 10000 to 59999 range, which replaces the 4-digit code previously used.
