*Includes only the civilian, noninstitutionalized population.

**A Metropolitan Statistical Area (MSA) includes at least: one city with 50,000 or more inhabitants, or a Census Bureau-defined urbanized area (of at least 50,000 inhabitants) and a total metropolitan population of at least 100,000 (75,000 in New England). Additional “outlying counties” are included in the MSA if they meet specified requirements of commuting to the central counties and other selected requirements of metropolitan character. In New England, the MSAs are defined in terms of cities and towns rather than counties.
