ES202 > Redefinition of MSA|
In 2000, the federal Office of
Management and Budget (OMB) revised the standards for defining federal
statistical areas. It was then announced in 2003 that statistical area
definitions would be updated to follow the new standards in 2005. The
updated Metropolitan Statistical Areas (MSAs) are defined in terms of
whole counties and must meet two criteria based on the 2000 Census.
Each MSA must include
the changes are implemented in January 2005, Oklahoma will be left with
three MSAs: Lawton, Oklahoma City and Tulsa. Enid, which has qualified
under previous guidelines, will lose MSA status because its urban area
population is less than 50,000.
Population won’t be the only factor affecting the state, as commuting
patterns will also force change. LeFlore County in eastern Oklahoma will
join Sequoyah County as part of the Fort Smith (Arkansas) MSA. In
addition, two of the remaining three MSAs for the state will see changes
in their county makeup. The Oklahoma City MSA (Canadian, Cleveland,
Grady, Lincoln, Logan, McClain and Oklahoma counties) will add Grady and
Lincoln Counties but drop Pottawatomie County. The Tulsa MSA (Creek,
Okmulgee, Osage, Pawnee, Rogers, Tulsa and Wagoner counties) will add
Okmulgee and Pawnee counties. The Lawton MSA will remain as is.
For the Oklahoma City and Tulsa MSAs, Quarterly Census of Employment and
Wages data for 4th quarter 2004 and before will not be
comparable with data published using the new definitions due to the
addition and subtraction of counties. These new MSA definitions will be
implemented with the release 1st quarter 2005 employment
data. To address data comparability issues, historical data from 1st
quarter 2001 to 4th quarter 2004 have been revised to
incorporate the changes. Historical data with the new MSA definition is
available online in the New MSA tab. In the mean time, we will only
provide Old MSA data up to 4th quarter 2004.
