This collection contains electronic versions of the Uniform
Crime Reports publications for the early years of the Uniform Crime
Reporting Program in the United States. The reports, which were
published monthly from 1930 to 1931, quarterly from 1932 to 1940, and
annually from 1941 to 1959, consist of tables showing the number of
offenses known to the police as reported to the Federal Bureau of
Investigation by contributing police departments. The term "offenses
known to the police" includes those crimes designated as Part I
classes of the Uniform Classification code occurring within the police
jurisdiction, whether they became known to the police through reports
of police officers, citizens, prosecuting or court officials, or
otherwise. They were confined to the following group of seven classes
of grave offenses, historically those offenses most often and most
completely reported to the police: felonious homicide, including
murder and nonnegligent manslaughter, and manslaughter by negligence,
rape, robbery, aggravated assault, burglary -- breaking and entering,
and larceny -- theft (including thefts $50 and over, and thefts under
$50, and auto theft). The figures also included the number of
attempted crimes in the designated classes excepting attempted murders
classed as aggravated assaults. In other words, an attempted burglary
or robbery, for example, was reported in the same manner as if the
crimes had been completed. "Offenses known to the police" included,
therefore, all of the above offenses, including attempts, which were
reported by the police departments and not merely arrests or cleared
cases.
