Metro and micro areas, otherwise known as Core Based Statistical Areas (CBSA), are geographic entities delineated by the Office of Management and Budget (OMB) for use by Federal statistical agencies. A metro area contains a core urban population of 50,000 or more, and a micro area contains an urban core population of at least 10,000 (but less than 50,000). Metro and micro areas may consist of one or more counties based on a region’s core urban area, or one or more counties that have a high degree of social and economic interactions, such as commuting patterns, wholesaling, commodity distribution, and recreational activities. Metro and micro area data are only available for download as a Comma Separated Values file (.csv file extension)—Data items are separated by commas, where each new line represents a new row.
