Definition
A Metropolitan Statistical Area (MSA) is a geographic region defined by the U.S. Office of Management and Budget (OMB) that contains at least one urbanized area with a minimum population of 50,000. MSAs are significant for the grouping of counties and cities based on their social and economic ties, aiding in the analysis of demographic and economic statistics.
Comparison: MSA vs. Micropolitan Statistical Area (µSA)
| Feature | Metropolitan Statistical Area (MSA) | Micropolitan Statistical Area (µSA) |
|---|---|---|
| Population | At least 50,000 in urbanized areas | At least 10,000 but less than 50,000 |
| Geographic extent | Generally larger, includes urban and suburban areas | Generally smaller, often includes a core city with surrounding towns |
| Economic Importance | Major economic center | Smaller economic center, often reliant on nearby MSAs |
| Census Data | More substantial demographic data available | Limited demographic data compared to MSAs |
Examples of MSAs
- New York-Newark-Jersey City, NY-NJ-PA MSA: One of the largest MSAs in the U.S., featuring high-density population and economic activities.
- Los Angeles-Long Beach-Anaheim, CA MSA: Known for its entertainment industry and sprawling suburban areas.
- Chicago-Naperville-Elgin, IL-IN-WI MSA: A hub for finance, technology, and transportation in the Midwest.
Related Terms
- Urbanized Area: An area with a population of 50,000 or more that is characterized by high population density and urbanization.
- Census: A count of the population, typically conducted every ten years in the U.S., which plays a crucial role in determining MSAs.
- Rural Areas: Regions outside urbanized areas which typically have lower population density.
Formula for Determining Population Density in MSAs
\[ \text{Population Density} = \frac{\text{Total Population}}{\text{Land Area}} \]
