Definition
A Metropolitan Statistical Area (MSA) is a geographic region with a relatively high population density at its core and close economic ties throughout the area. MSAs are defined by the United States Office of Management and Budget (OMB) and used by the U.S. Census Bureau and other agencies for gathering standardized statistical data. Typically, an MSA must have a core urban area with at least 50,000 residents.
Examples
- Atlanta, Georgia: The Atlanta-Sandy Springs-Roswell, GA MSA covers 29 counties and includes a population of over 6 million people.
- Los Angeles, California: The Los Angeles-Long Beach-Anaheim, CA MSA consists of just one county, Los Angeles County, which is the most populous county in the U.S. with more than 10 million inhabitants.
- Dallas-Fort Worth, Texas: The Dallas-Fort Worth-Arlington, TX MSA spans 13 counties and has a population exceeding 7 million people.
Frequently Asked Questions (FAQs)
What criteria are used to define an MSA?
To define an MSA, the central county (or counties) must have at least one urbanized area with a population of 50,000 or more. Adjacent counties must have a high degree of social and economic integration with the central county, typically measured by commuting patterns.
How often are MSA boundaries updated?
The Office of Management and Budget (OMB) reviews and updates MSA boundaries based on new census data, which occurs every 10 years.
Why are MSAs important?
MSAs are crucial for accurately collecting, analyzing, and comparing statistical data for highly urbanized areas. This helps businesses, policymakers, and researchers make informed decisions based on a consistent and comparable framework.
Can an MSA include multiple cities?
Yes, an MSA can encompass multiple cities and towns that are economically and socially linked, although they may be politically independent.
