The Role of Social Science

The introduction of the Uniform Crime Reporting system (UCR) in 1930 remains one of the most important events in the history of criminal statistics in the United States. Based on local police reports, it is the oldest extant national crime data system in the United States, with the possible exception of prison statistics. It continues to be a vitally important data system because of its extensive use by scholars, social critics, governmental organizations and the media, and as such it has made a major contribution to our understanding of crime in the United States in the last half century. The UCR has also had its share of controversy, involving not only scientific issues of validity and reliability, but the possibility of covert agendas on the part of the police and the FBI to foster an image of effective law enforcement. Despite its importance and controversial nature there is no single objective and definitive written history documenting the beginnings of the UCR. That which exists tends to be brief and superficial, and at times even ideologically biased (Leonard 1954; Maltz 1977; Sherman et al. 1982; Thompson 1968; U.S. Federal Bureau of Investigation 1940).
