Micropolitan statistical area

A core based statistical area associated with at least one urban cluster that has a population of at least 10,000, but less than 50,000. The micropolitan statistical area comprises the central county or counties containing the core, plus adjacent outlying counties having a high degree of social and economic integration with the central county as measured through commuting.

Counties contained in micropolitan statistical areas are nonmetropolitan.

For more information on how metropolitan areas are delineated, see The Census Bureau.
