Data Viz of the Week: What Are Metropolitan Statistical Areas?

Metropolitan Statistical Areas, or MSA’s, is a term often used when describing data geography. MSA’s are defined as:

Geographic entities delineated by the Office of Management and Budget (OMB) for use by Federal statistical agencies in collecting, tabulating, and publishing Federal statistics.  A MSA contains a core urban area of 50,000 or more population. Each metro area consists of one or more counties and includes the counties containing the core urban area, as well as any adjacent counties that have a high degree of social and economic integration (as measured by commuting to work) with the urban core.

How and why are MSA’s useful?

  • The Federal Office of Rural Health Policy uses MSA’s as part of their criteria in defining rural areas;
  • Large businesses use MSA’s to help determine sales territories.
