Core-Based Statistical Area (CBSA) Change in North Carolina
The US Office of Management and Budget (OMB) maintains the standards for defining metropolitan areas in the United States. Core-Bases Statistical Areas (CBSAs) is the collective term for Metropolitan Statistical Areas (based on urban area cores of 50,000 or more), Micropolitan Statistical Areas (based on urban cores from 10,000 to 50,000), or Combined Statistical Areas (neighboring Metropolitan and/or Micropolitan Statistical Areas combined into an integrated statical geography). CBSAs are comprised of counties containing the urban core and neighboring counties with a high degree of commuting into the core counties.
This visualization uses 2020 Census total population to compare changes in CBSA definition.
CBSA designation should not be confused with urban/rural designation. CBSAs are comprised of entire counties. Counties included in CBSAs may contain rural areas, and non-CBSA counties may contain urban areas.
