June 2026 .. this section provides an interactive iVDA map and table showing Core-Based Statistical Area (CBSA) and component county population and components of change from 2020 to 2024 intended for introductory and more advanced users. Marketing to the right demographic might be improved by using up-to-date measures for metro population by age. These data show that population growth slowed in a majority of the nation's 3,143 counties and D.C. between July 1, 2024, and July 1, 2025, In 2024, the United States 925 2023 vintage metropolitan areas comprised 94.7% (316,997,304) of the total population (334,914,895).

Approximately 73% of the nation's 387 metro areas (Metropolitan Statistical Areas - MSAs) experienced population growth between 2024 and 2025. A smaller percentage of U.S. micro areas (Micropolitan Statistical Areas - MISAs) experienced population growth over the same period, with approximately 58% (314 out of 538) MISAs having gains in population .. based on Census Bureau model based estimates (March 2026).

Metropolitan areas as used here refers to Metropolitan Statistical Areas (MSAs) and Micropolitan Statistical Areas (MISAs), and together Core-Based Statistical Areas (CBSAs). CBSAs are comprised of one or more contiguous counties.

About Metropolitan Areas ... goto top
New Vintage 2023 CBSA/metro delineations are available as of August 2023. See more about the 2023 delineations. Core-Based Statistical Areas (CBSAs) are officially designated by OMB and composed of one or more contiguous counties and must meet a population size criteria of associated Urban Area. CBSAs are classified as the larger Metropolitan Statistical Areas (MSAs) and smaller Micropolitan Statistical Areas (MISAs). Use the interactive table to view, rank, query 2023 vintage CBSAs by component area based on Vintage 2025 population estimates and components of change.

The U.S. Office of Management and Budget (OMB) delineates metropolitan and micropolitan statistical areas according to standards applied to Census Bureau and related data. A metropolitan or micropolitan statistical area has a core area containing a substantial population nucleus, together with adjacent areas having a high degree of economic and social integration with that core. See 2020 Standards for Delineating Core Based Statistical Areas published in the Federal Register.

The term "Core-Based Statistical Area" (CBSA) refers collectively to metropolitan and micropolitan statistical areas. Each CBSA must contain at least one urban area of 10,000 or more population. Each metropolitan statistical area (MSA) must have at least one urbanized area of 50,000 or more inhabitants. Each micropolitan statistical area (MISA) must have at least one urban cluster of at least 10,000 but less than 50,000 population.

The largest city in each metropolitan or micropolitan statistical area is designated a "principal city." Additional cities qualify if specified requirements are met concerning population size and employment. The title of each metropolitan or micropolitan statistical area consists of the names of up to three of its principal cities and the name of each state into which the metropolitan or micropolitan statistical area extends.

Individual CBSAs (MSAs and MISAs) are defined as one or more contiguous counties. Combined Statistical Areas (CSAs) are defined as a set of two or more contiguous CBSAs.

County Building Blocks. Current vintage metropolitan and micropolitan statistical area (CBSA) designations are comprised of county building blocks as defined by OMB and updated from time-to-time.
