September 2019 .. a Combined Statistical Area (CSA) is a group of two or more adjacent metropolitan areas; they include contiguous metro counties that have demographic-economic affinity. These 172 areas (September 2018 vintage) are important in wide-ranging geographic and demographic analysis. Based on the 2018 population estimate, these areas include 256.2 million population of the total U.S. population of 327.2 million (78.3 percent). CSAs are at least two adjacent metropolitan areas -- reflecting a larger and broader market/service/impact assessment area. Due to their size (of many), it is often possible to develop more detailed custom demographic-economic estimates and projections than at the county or metropolitan area level. See more below about CSA definitions and relation to other geography. Use ProximityOne CSA demographic projections to 2060 to examine how CSA population is changing. Annual estimates and projections are developed at the county and metro levels enabling analysis of trends and patterns at the CSA and component CSA geography. Contact us for details. This section provides an overview of recent demographic trends among CSAs and provides access to tools to further examine these areas, markets, and demographic-economic-business related characteristics. Use the interactive table below to examine patterns and relationships among CSAs of interest. Use the GIS project and datasets described below to examine CSAs in a mapping and geospatial analysis context. Patterns of 2018 Population by 2018 CSA The following graphic shows the September 2018 vintage CSAs based on the 2018 official population estimates. The intervals/colors are depicted in legend panel at left of map window. Create custom maps similar to this view for your regions of interest. Use the GIS project/datasets to examine alternative patterns such as percent change for different time periods. Set queries to include CSAs by peer group.

CSAs and CBSAs are geographic delineations defined by OMB based on demographic-economic data developed by the Census Bureau. See related terms below. CSAs are not all huge populated areas; they range from less than 40,000 population to more than 23 million population. Some metros than might seem to be included as CSAs are not. The Phoenix, AZ metro would be the 13th largest CSA based on population size but is not a CSA as it has not adjacent MSA or MISA. Codes for Metropolitan Statistical Areas, Micropolitan Statistical Areas, and Related Statistical Areas. Codes for metropolitan and micropolitan statistical areas (collectively referred to as "Core Based Statistical Areas" or "CBSAs"), metropolitan divisions, Metropolitan divisions are distinguished by a 5-digit code ending in "4." Combined Statistical Area Consists of two or more adjacent core based statistical areas (CBSAs) that have an employment interchange measure of 15 or more. Core Based Statistical Areas (CBSAs) Refer collectively to metropolitan statistical areas and micropolitan statistical areas. CBSAs consist of the county or counties (or equivalent entities) associated with at least one core (urbanized area or urban cluster) of at least 10,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties. Employment Interchange Measure (EIM) Is a measure of ties between two adjacent entities. It is the sum of the percentage of workers living in the smaller entity who work in the larger entity and the percentage of employment in the smaller entity that is accounted for by workers who reside in the larger entity. Metropolitan Division A county or group of counties (or equivalent entities) delineated within a larger metropolitan statistical area, provided that the larger metropolitan statistical area contains a single core with a population of at least 2.5 million and other criteria are met. A Metropolitan Division consists of one or more main/secondary counties that represent an employment center or centers, plus adjacent counties associated with the main/secondary county or counties through commuting ties. Not all metropolitan statistical areas will contain metropolitan divisions. Metropolitan Statistical Area A geographic entity delineated by the Office of Management and Budget for use by federal statistical agencies. Metropolitan statistical areas consist of the county or counties (or equivalent entities) associated with at least one urbanized area of at least 50,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties. Metropolitan and micropolitan statistical areas are collectively referred to as "Core Based Statistical Areas" (CBSAs). Micropolitan Statistical Area A geographic entity delineated by the Office of Management and Budget for use by federal statistical agencies. Micropolitan statistical areas consist of the county or counties (or equivalent entities) associated with at least one urban cluster of at least 10,000 but less than 50,000 population, plus adjacent counties having a high degree of social and economic integration with the core as measured through commuting ties. Metropolitan and micropolitan statistical areas are collectively referred to as "Core Based Statistical Areas" (CBSAs). Principal City The largest incorporated place with a population of at least 10,000 in a core based statistical area (CBSA), or if no incorporated place of least 10,000 population is present in the CBSA, the largest incorporated place or census designated place (CDP) in the CBSA. Additional places that meet specific criteria are also identified as principal cities. Support Using these Resources Learn more about demographic economic data and related analytical tools.
