  "term": "Primary Metropolitan Statistical Area",
  "field": "Economic statistics",
  "definition": "Formerly, a geographic entity delineated by the Office of Management and Budget for use by federal statistical agencies. If an area met the requirements to qualify as a metropolitan statistical area and had a population of one million or more, two or more PMSAs were delineated within it if statistical criteria were met and local opinion was in favor. A PMSA consisted of one or more counties (county subdivisions in New England) that had substantial commuting interchange. When two or more PMSAs were recognized, the larger area of which they are components then was designated a consolidated metropolitan statistical area (CMSA). The PMSA concept was retired in 2003 with the introduction of the Metropolitan Division concept.",
