Useful Web Tool on Woods & Poole Home Page

March 7, 2023

On the Home Page ( is a useful web tool at the bottom of the page that enables you to find the names and FIPS codes of counties making up any metropolitan area in the U.S.

Type in the name or FIPS code of a Metropolitan Statistical Area (MSA), Combined Statistical Area (CSA), Micropolitan Statistical Area (MICRO), or Metropolitan Division (MDIV) and a list of all the counties in the MSA, CSA, MDIV or MICRO will appear in a drop-down screen.  If you type in any part of the name of a metropolitan area the full name will appear in a selectable drop down.

You can also enter a county name or FIPS code and see a list of all the metropolitan areas (MSA, CSA, MDIV and MICRO), if any, of which the county is a part.

The county definitions are from the 2022 Woods & Poole regional database and the metropolitan areas are as defined in the September 14, 2018, Office of Management and Budget (OMB BULLETIN NO. 18-04), Revised Delineations of Metropolitan Statistical Areas, Micropolitan Statistical Areas, and Combined Statistical Areas, and Guidance on Uses of the Delineations of These Areas.

There are 384 MSAs, 172 CSAs, 542 MICROs, and 31 MDIVs in the 2021 Woods & Poole database.

All Core Based Statistical Areas (CBSAs) are included in the Woods & Poole database.  CBSAs are MSAs or MICROs;  CBSA is a collective term for both of these geographies.  There are 926 CBSAs in the Woods & Poole database, based on the 2018 OMB definitions.

When the final Census 2020 data are released CBSA definitions will undergo a comprehensive revision by the OMB.  Woods & Poole will incorporate the new CBSA definitions when they become available (expected in June 2023) and this data tool will be updated.
