INTRODUCTION
The Office of Management
and Budget (OMB) defines metropolitan areas (MAs) following the
official standards published in the Federal Register (55 FR 12154-12160)
on March 30, 1990. MAs comprise metropolitan statistical areas (MSAs),
consolidated metropolitan statistical areas (CMSAs), and primary
metropolitan statistical areas (PMSAs). These areas are defined
in terms of entire counties, except in the six New England States
where they are defined in terms of cities and towns. New England
county metropolitan areas (NECMAs) are an alternative set of county-based
areas defined for New England states.
Effective June 30, 1995,
there are 256 MSAs, 19 CMSAs, and 76 PMSAs, including 3 MSAs, 1
CMSA, and 3 PMSAs in Puerto Rico. Attached are four lists containing
the definitions of these areas based on the MA standards published
in the Federal Register on March 30, 1990, the 1990 Decennial Census
data, and 1992 and 1994 Census Bureau population estimates. List
I is a comprehensive alphabetical listing of all MSAs, CMSAs, and
PMSAs. It presents the definition and central cities for each MSA,
and identifies each CMSA and PMSA by title only (referring the user
to List II for their definitions). List II provides definitions
of each CMSA and its component PMSAs. Both List I and List II present
central cities in the order in which they appear in the area title
and then in descending order of their 1990 populations. List III
identifies the MSAs, CMSAs, and PMSAs by State, with cross references
to the list on which to find each area's definition and central
cities. Parentheses around MA titles in List III indicate that an
area recently has become part of another or has a new title. List
IV specifies the definitions of 12 NECMAs.
The first column of
each list contains Federal Information Processing Standards (FIPS)
codes issued by the National Institute of Standards and Technology
(NIST) in the Department of Commerce to standardize the coding of
electronic data processing information. NIST has assigned a unique
four digit code for each MSA, PMSA, and NECMA and a unique two digit
code for each CMSA.
