The Uniform Crime Reports National Time-Series Data,
1967-1980, include detailed criminal offense and clearance information
submitted monthly by over 3,000 consistently reporting law enforcement
agencies in the United States. These data, provided in annually pooled
cross-sections, were processed at the Center for Applied Social
Research, Northeastern University, Boston, Massachusetts to produce
easily accessible and highly reliable time-series data on officially
reported crime. Originally provided by the Federal Bureau of
Investigation (FBI), these data exclude Uniform Crime Report (UCR)
data from infrequently reporting law enforcement agencies. In general,
only those agencies that submitted ten or more monthly reports in
every year during 1967 through 1980 are included in this collection.
The data include detailed breakdowns of offenses and clearances taken
from disaggregated UCR Return A tapes. Of particular interest are
weapon-specific robbery and assault variables, types of rape,
burglary, larceny, and motor vehicle theft, and clearances by arrest
(or other exceptional means) of adults and juveniles for each offense
sub-type. Both monthly and annual counts of these are available.
Finally, as an aid to the user, each agency is identified by its FBI
"ORI Code" as well as a sequential case number produced and documented
by ICPSR in the codebook's appendix. Cases also may be identified by
geographic region, state, SMSA, county, population size and group, and
frequency of reporting.
