Visualizing Metro Area Geography

.. metropolitan areas are referred to as CBSAs (Core-Based Statistical Areas) and formally defined as sets of contiguous counties for the Federal Statistical System by OMB based largely on Census Bureau data.  More than 93-percent of the U.S. population live in CBSAs. This post presents three map graphics showing the geographic configuration of CBSAs and related CSAs (Combined Statistical Areas) — groupings of contiguous CBSAs that meet certain criteria. See related Web section for more detail.

The graphics below use the September 2018 CBSA vintage, the current and likely to be used for Census 2020 tabulations. These CBSAs are comprised of 392 Metropolitan Statistical Areas (MSAs), 384 MSAs in the U.S. and 8 in Puerto Rico, and 546 Micropolitan Statistical Areas (MISAs), 542 in the U.S. and 4 in Puerto Rico. For those MSAs that qualify, 11 MSAs are subdivided into 31 Metropolitan Divisions (MDs).

Metro Demographic-Economic Insights. What are the demographic characteristics of metros, how are they changing? We have developed annual population and population components of change estimates for the September 2018 vintage CBSAs.  Access these data in this interactive table. View CBSA county components. These data are integrated with other data to develop wide-ranging demographic-economic current estimates and projections for CBSAs and other geography (Situation & Outlook).
