METROPOLITAN AREAS 1995 LISTS I-IV Statistical Policy
Office Office of Management and Budget Attachments to OMB Bulletin No.
95-04
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.
