County Composition of All Metropolitan Areas, 1900-2011
The tables linked to below list the counties associated with each metro area identified by METAREA for each sample since 1900. For tables listing county composition back to 1850, see County Composition of Older Metropolitan Areas.
For 2000 samplesand for all ACS and PRCS samples through 2011, METAREA uses the 1999 metropolitan area delineations from the Office of Management and Budget (OMB), as were used for Census 2000 reporting. Beginning with the 2010 Decennial Census and the 2012 ACS and PRCS samples, IPUMS provides a separate variable, MET2013, that identifies metro areas using the 2013 OMB delineations and codes. For a listing of counties associated with the 2013 areas, see the Census Bureau's 2013 "List 1" Delineation File.
Users are advised to check the area-specific notes at the end of each table.
