Definition
A Core-Based Statistical Area (CBSA) is a geographical region defined by the Office of Management and Budget (OMB) that centers on an urban area (city or town) with a population of at least 10,000. CBSAs are further classified into two subcategories based on the population size of the core urban area:
- Metropolitan Statistical Areas (MSA): Urban areas with a core population of at least 50,000.
- Micropolitan Statistical Areas: Urban areas with a core population between 10,000 and 49,999.
CBSAs are used by various government agencies and businesses for statistical, planning, and policy-making purposes.
Examples
- New York Metropolitan Statistical Area (MSA): As per the 2010 census, the New York MSA is the largest CBSA with over 19.3 million inhabitants. It includes New York City and parts of New Jersey and Connecticut.
- State College, Pennsylvania Micropolitan Statistical Area: An example of a Micropolitan Statistical Area with an urban core population between 10,000 and 49,999.
- Tullulah, Louisiana: According to the 2010 census, this is classified as the smallest CBSA with approximately 12,000 residents.
Frequently Asked Questions (FAQs)
Q1: What is the purpose of defining CBSAs? A: CBSAs help in organizing and analyzing demographic data, determining areas for federal funding, planning regional development, and understanding local economies.
Q2: How often are CBSAs updated? A: CBSAs are typically updated each decade following the comprehensive population census but can be revised periodically based on new data and urban development.
Q3: How do CBSAs affect real estate markets? A: Understanding the classification and trends of CBSAs allows real estate professionals to make data-driven investment decisions, recognizing areas of growth or decline.
Q4: Can areas move between Micropolitan and Metropolitan status? A: Yes, as population dynamics change, urban areas can shift categories. Growth in population may boost a Micropolitan Statistical Area to a Metropolitan Statistical Area, and conversely, population decline can reverse the shift.
Q5: What are the differences between CBSAs and Combined Statistical Areas (CSAs)? A: Combined Statistical Areas (CSAs) are larger geographic entities created when two or more adjacent CBSAs have significant employment interchange and socio-economic ties.
