Statistical Definitions of Metropolitan
Areas (MAs) and Guidance on Uses of MA Definitions
Purpose: This Bulletin establishes two new Metropolitan Statistical Areas
(MSAs) and a new central city in an existing MSA. It also provides
guidance on the use of the statistical definitions of Metropolitan
Background: Pursuant to 44 U.S.C. 3504(d)(3) and 31 U.S.C. 1104(d) and E.O.
No. 10253 (June 11, 1951), the Office of Management and Budget
(OMB) defines MAs for use in Federal statistical activities. OMB
updates these definitions each June, adding new areas that qualify
as MAs and cities that qualify as central cities for MAs.
New MSAs: Flagstaff, Arizona-Utah, is defined as a Level CMSA (FIPS Code
2620) effective June 30, 1995. The Flagstaff, Arizona-Utah MSA
comprises Coconino County, Arizona, and Kane County, Utah. Its
central city is Flagstaff, Arizona.
Grand Junction, Colorado, is defined as a Level D MSA (FIPS Code 2995)
effective June 30, 1995. The Grand Junction, Colorado MSA comprises
Mesa County, Colorado. Its central city is Grand Junction, Colorado.
city: Lenoir, North Carolina qualifies as a new central city
of the Hickory-Morganton, NC MSA (FIPS Code 3290). With this central
city addition, the title for the MSA becomes Hickory-Morganton-Lenoir,
Areas: This Bulletin gives the definitions of all MAs in the
United States and Puerto Rico, based on the standards published
on March 30, 1990, in the Federal Register (55 FR 12154-12160),
the 1990 Decennial Census data, and 1992 and 1994 Census Bureau
population estimates. A total of 256 Metropolitan Statistical
Areas (MSAs) are recognized. There are 19 Consolidated Metropolitan
Statistical Areas (CMSAs), consisting of 76 Primary Metropolitan
Statistical Areas (PMSAs). List I provides titles and definitions
of all MSAs; List II presents similar information for CMSAs and
PMSAs. List III identifies the MSAs, CMSAs, and PMSAs of each
State. List IV provides titles and definitions for the New England
County Metropolitan Areas (NECMAs). MSAs, PMSAs, and NECMAs are
categorized by their 1990 population size, as follows:
A -- Areas of 1 million or more
Level B -- Areas of 250,000 to 999,999
Level C -- Areas of 100,000 to 249,999
Level D -- Areas of less than 100,000
of Metropolitan Area Definitions: All agencies that conduct
statistical activities to collect and publish data for MAs should
use the most recent definitions of MAs established by OMB.
and maintains the definitions of the MAs solely for statistical
purposes. In periodically reviewing and revising the MA definitions,
OMB does not take into account or attempt to anticipate any
nonstatistical uses that may be made of the definitions, nor
will OMB modify the definitions to meet the requirements of
any nonstatistical program.
that some legislation specifies the use of metropolitan areas
for programmatic purposes, including allocating Federal funds.
For example, as called for by the Social Security Act, 42 U.S.C.
1882(d)(2), the Health Care Financing Administration uses MAs
to define labor market areas and gather hospital wage data that
are used in developing a hospital wage index for the labor related
portion of a hospital's standardized Medicare payment. We will
continue to work with the Congress to clarify the foundations
of the metropolitan area definitions and the resultant, often
unintended consequences of their use for nonstatistical purposes.
where there is no statutory requirement and an agency elects
to use the MA definitions in a nonstatistical program, it is
the sponsoring agency's responsibility to ensure that the definitions
are appropriate for such use. When an agency is publishing for
comment a proposed regulation that would use the MA definitions
for a nonstatistical purpose, the agency should seek public
comment on the proposed use of the MA definitions. Please refer
to M-94-22 on Use of Metropolitan Area Definitions issued by
OMB on May 5, 1994, for further information.
