Metropolitan statistical area

A core based statistical area associated with at least one urbanized area that has a population of at least 50,000. The metropolitan 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.

When the local area personal income* and GDP by metropolitan area statistics are updated, the most current delineations available from the Office of Management and Budget (OMB) are carried through the entire time series.

*Real Personal Income are estimated for the most current delineations available from the Office of Management and Budget (OMB) and carried through the entire time series for as many regions as possible. Combining metropolitan areas with the U.S. nonmetropolitan portion provides complete coverage of all U.S. counties.

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