Excerpt from Uniform Crime Reports for the United States, 1991 Essential to law enforcement planning and policy is timely and accurate information. Administered by the fbi since 1930, the Uniform Crime Reporting (ucr) Program has provided an important component of this information. Throughout the decades, continual effort has been made to improve quality, coverage, and presentation of the crime data supplied to the Program by law enforcement agencies across the country. Enhancements - As part of that effort, several enhancements have been made to this year's Crime in the United States. Among the changes are an expansion in the time period for which Crime Index figures are presented, improved measures of seasonal variations in crime, enhanced references to tables and graphics, and more information about murder. New Feature - A new feature is an examination of a currently important topic. This year's focus is upon arrests for juvenile violent, drug, and weapon offenses during the past 25 years. Telephone Guide - While this publication provides a wealth of information, many users will desire additional detail and explanation. To assist these users, as well as data providers with questions concerning data submissions, a telephone guide has been included to facilitate inquiries.
