National Crime Victimization Survey: MSA Data, 1979-2004

The National Crime Victimization Survey (NCVS), previously
the National Crime Survey (NCS), has been collecting data on personal
and household victimization through an ongoing survey of a
nationally-representative sample of residential addresses since 1973.
The survey is administered by the United States Census Bureau (under
the United States Department of Commerce) on behalf of the Bureau of
Justice Statistics (under the United States Department of Justice).
Occasionally there have been extract or supplement files created from
the NCVS and NCS data series. This extract contains two data files, a
weighted person-based file, and a weighted incident-based file, which
contain the "core" counties within the top 40 National Crime
Victimization Survey Metropolitan Statistical Areas (MSAs). Core
counties within these MSAs are defined as those self-representing
primary sampling units that are common to the MSA definitions
determined by the Office of Management and Budget for the 1970-based,
1980-based, and 1990-based sample designs. Each MSA is comprised of
only the core counties and not all counties within the MSA. The
person-based file contains select household and person variables for
all people in NCVS-interviewed households in the core counties of the
40 largest MSAs from January 1979 through December 2004. The
incident-based file contains select household, person, and incident
variables for persons who reported a violent crime within any of the
core counties of the 40 largest MSAs from January 1979 through
December 2004. Household, person, and incident information for persons
reporting non-violent crime are excluded from this file. The 40
largest MSAs were determined based on the number of household
interviews in an MSA.
