A '''core-based statistical area''' ('''CBSA''') is a [[United States|U.S.]] geographic area defined by the [[Office of Management and Budget]] (OMB). It contains a large population nucleus, or urban area, and adjacent communities that have a high degree of integration with that nucleus.<ref>[https://www.govinfo.gov/content/pkg/FR-2010-06-28/pdf/2010-15605.pdf 2010 Standards for Delineating Metropolitan and Micropolitan Statistical Areas]</ref>
