Frequently Asked Questions
What is a CBSA?
A Core Based Statistical Area (CBSA) is a U.S. geographic area defined by the Office of Management and Budget (OMB) based on commuting patterns and economic integration. CBSAs include both Metropolitan Statistical Areas (50,000+ population) and Micropolitan Statistical Areas (10,000-50,000 population).
Why are some ZIP codes not in any CBSA?
Rural ZIP codes that are not part of any Metropolitan or Micropolitan Statistical Area are classified as rural. These areas don't meet the population and commuting thresholds required for CBSA designation.
Can CBSAs cross state boundaries?
Yes, many CBSAs span multiple states. For example, the New York-Newark-Jersey City MSA includes portions of New York, New Jersey, and Pennsylvania. When viewing state data, you'll see all CBSAs that have any ZIP codes within that state.
