<P> Since 1935 , the FBI served as a data clearinghouse ; organizing , collecting , and disseminating information voluntarily submitted by local , state , federal and tribal law enforcement agencies . The UCR remained the primary tool for collection and analysis of data for the next half century . Throughout the 1980s , a series of National UCR Conferences were with members from the IACP , Department of Justice , including the FBI , and newly formed Bureau of Justice Statistics ( BJS ) . The purpose was to determine necessary system revisions and then implement them . The result of these conferences was the release of a Blueprint for the Future of the Uniform Crime Reporting Program release in May 1985 , detailing the necessary revisions . The report proposed splitting reported data into two separate categories , the eight serious crimes ( which later became known as `` Part I index crimes '' ) and 21 less commonly reported crimes ( which later became known as `` Part II index crimes '' ) . </P>
