Definition

A Combined Statistical Area (CSA) is a term used by the U.S. Census Bureau to describe a geographical region that consists of two or more adjacent Metropolitan Statistical Areas (MSAs), Micropolitan Statistical Areas (μSAs), or a combination of both. These areas are integrated economically and socially, showing significant commuting interconnections and other shared socioeconomic characteristics.

Examples

  1. New York-Newark, NY-NJ-CT-PA CSA: This CSA includes the New York City MSA, the Newark MSA, and several Micropolitan Statistical Areas in Connecticut and Pennsylvania, reflecting the large interconnected economic region around New York City.

  2. Los Angeles-Long Beach, CA CSA: Comprising the Los Angeles MSA and several surrounding μSAs like Riverside-San Bernardino, this CSA demonstrates the extensive commuting patterns and economic linkages in Southern California.

Frequently Asked Questions

1. What is the purpose of defining a Combined Statistical Area (CSA)?

Defining a CSA helps in the analysis of regional economic activities, commuting patterns, and social interconnections. It provides a broader understanding of the interconnectedness between different areas and helps in regional planning and policy-making.

2. How is a CSA different from an MSA?

An MSA is a single metropolitan area with a core urban area of 50,000 or more population and its adjacent territories showing economic and social integration. A CSA, on the other hand, encompasses multiple MSAs or μSAs that are economically linked, indicating a broader region of interconnected metropolitan and micropolitan areas.

3. Who defines and updates the boundaries of CSAs?

The U.S. Office of Management and Budget (OMB) is responsible for defining and updating the boundaries of CSAs based on data collected primarily by the U.S. Census Bureau.

4. How often are CSAs updated?

Combined Statistical Areas are reviewed and updated after each decennial census, reflecting changes in population and commuting patterns.

  1. Metropolitan Statistical Area (MSA): A geographical region with a core urban area of at least 50,000 population and encompassing areas with a high degree of social and economic integration with the core, as defined by commuting ties.

  2. Micropolitan Statistical Area (μSA): A smaller-scale MSA with an urban core of at least 10,000 but less than 50,000 population, also featuring strong socio-economic ties with adjacent areas.

  3. Core-Based Statistical Area (CBSA): This encompasses both Metropolitan and Micropolitan Statistical Areas, used collectively to determine regions surrounding urbanized cores.

Fundamentals of Combined Statistical Area: Geography Basics Quiz

### How does the U.S. Census Bureau define a Combined Statistical Area (CSA)? - [ ] A single urban area with more than 100,000 people. - [x] A combination of adjacent Metropolitan Statistical Areas or Micropolitan Statistical Areas. - [ ] A rural area with scattered development. - [ ] A single Metropolitan Statistical Area. > **Explanation:** A Combined Statistical Area (CSA) is defined by the U.S. Census Bureau as a grouping of adjacent metropolitan and/or micropolitan statistical areas that have strong economic ties. ### What is the key criterion for areas to be combined into a CSA? - [ ] Geographic proximity alone - [x] Economic interconnections - [ ] Aligned state boundaries - [ ] Similar population sizes > **Explanation:** The primary criterion for combining areas into a CSA is the presence of significant economic ties, such as commuting patterns, that link the areas closely together. ### Who is responsible for defining CSAs? - [ ] Local city councils - [ ] State governments - [x] U.S. Office of Management and Budget (OMB) - [ ] The Department of Transportation > **Explanation:** The U.S. Office of Management and Budget (OMB) is responsible for defining and regularly updating the boundaries of Combined Statistical Areas. ### How frequently are CSA boundaries reviewed and updated? - [ ] Annually - [ ] Every five years - [ ] Every twenty years - [x] After every decennial census > **Explanation:** CSA boundaries are reviewed and updated after every decennial census to account for changes in population and commuting patterns. ### Which of the following is NOT part of a CSA? - [ ] Metropolitan Statistical Area (MSA) - [ ] Micropolitan Statistical Area (μSA) - [x] Rural Statistical Area (RSA) - [ ] Core-Based Statistical Area (CBSA) > **Explanation:** "Rural Statistical Area (RSA)" is not a recognized term by the U.S. Census Bureau for the inclusion in a Combined Statistical Area. CSAs include MSAs and μSAs. ### Can a CSA include both metropolitan and micropolitan areas? - [x] Yes - [ ] No > **Explanation:** Yes, a CSA can consist of a combination of Metropolitan Statistical Areas (MSAs) and Micropolitan Statistical Areas (μSAs) linked by economic ties. ### Which of these is a prominent example of a large CSA? - [ ] Seattle, WA - [x] New York-Newark, NY-NJ-CT-PA CSA - [ ] Denver, CO - [ ] Portland, OR > **Explanation:** The New York-Newark, NY-NJ-CT-PA CSA is a prominent example of a large CSA, encompassing numerous metropolitan and micropolitan areas connected by strong economic interlinks. ### What does the acronym μSA stand for? - [x] Micropolitan Statistical Area - [ ] Micro Societal Area - [ ] Medium-sized Statistic Area - [ ] Main Statistical Area > **Explanation:** μSA stands for Micropolitan Statistical Area, which refers to urban regions with a core population of at least 10,000 but less than 50,000. ### What term is used to collectively encompass both Metropolitan and Micropolitan Statistical Areas? - [ ] Combined Metropolitan Area - [x] Core-Based Statistical Area (CBSA) - [ ] Regional Statistical Area - [ ] Greater Metropolitan Area > **Explanation:** Core-Based Statistical Area (CBSA) is a term used to collectively describe both Metropolitan and Micropolitan Statistical Areas. ### What determines the "economic ties" between areas in a CSA? - [ ] Similar tax rates - [ ] Same municipal governance - [x] Commuting patterns and economic interdependencies - [ ] Alike geographical features > **Explanation:** Economic ties between areas in a CSA are often determined by commuting patterns and economic interdependencies that reflect strong social and economic connections.
