Metropolitan Statistical Area (MSA)

Metropolitan Statistical Area MSA Urbanized Area Social Integration Economic Integration Commuting Census Data
A Metropolitan Statistical Area (MSA) is a Core-Based Statistical Area associated with at least one urbanized area with a population of at least 50,000. An MSA comprises the central county or counties containing the core, plus adjacent outlying counties with a high degree of social and economic integration with the central county as measured through commuting.

Definition

A Metropolitan Statistical Area (MSA) is a geographical region defined by the United States Office of Management and Budget (OMB) which centers around a significant urban area, typically with a population of at least 50,000. MSAs are typically composed of the central county or counties containing this urbanized core and adjacent outlying counties that demonstrate a high degree of socio-economic connectivity to the urban core, often determined by commuting patterns.

Key Characteristics:

  • Minimum Urbanized Core Population: 50,000.
  • Includes central county or counties.
  • Includes adjacent counties with substantial commuting to the central area.
  • High economic and social integration.

Examples

  1. New York-Newark-Jersey City, NY-NJ-PA MSA, which includes New York City and extends across numerous counties in New York, New Jersey, and Pennsylvania, illustrating a high degree of integration through commuting patterns.

  2. Los Angeles-Long Beach-Anaheim, CA MSA, encompassing the core city of Los Angeles and extending out to nearby areas like Long Beach and Anaheim.

  3. Chicago-Naperville-Elgin, IL-IN-WI MSA, which covers the core city of Chicago and a broader expanse that includes adjacent counties in Illinois, Indiana, and Wisconsin.

Frequently Asked Questions

Q1: What is the purpose of defining a Metropolitan Statistical Area?

A1: The primary purpose is for statistical and policy analysis, helping government and researchers understand social and economic patterns in significantly urbanized areas.

Q2: How is an MSA different from a Micropolitan Statistical Area?

A2: An MSA is centered around an urbanized area with a population of at least 50,000, while a Micropolitan Statistical Area centers around an urban cluster with a population between 10,000 and 50,000.

Q3: Can the boundaries of an MSA change?

A3: Yes, the OMB periodically reviews and updates the boundaries based on new census data and economic trends.

Q4: How are commuting patterns used to define an MSA?

A4: Commuting patterns reveal economic linkages and help determine the degree of social and economic integration between the core and outlying areas.

Q5: Is the concept of an MSA only used in the US?

A5: While the term is specific to the US, similar concepts are in use globally, often referred to as metropolitan areas or urban agglomerations.

  • Core-Based Statistical Area (CBSA): A region consisting either of a Metropolitan or Micropolitan Statistical Area.
  • Urbanized Area (UA): A densely settled area with a population of 50,000 or more people.
  • Micropolitan Statistical Area: An area centered around an urban cluster with a population between 10,000 and 50,000.
