"The FBI's Uniform Crime Reporting (UCR) Program collects counts of arrests (including citations and summonses) in several offense and demographic categories from participating state and local law enforcement agencies. For many years, the FBI has published national estimates of arrests based on these data in its 'Crime in the United States' series. In 'Crime in the United States, 2010', the FBI estimated that state and local law enforcement agencies made a total of 13,122,000 arrests in 2010, and provided national arrest estimates in 28 separate offense categories. This report expands the FBI's set of published national arrest estimates to include estimates of arrests in various age, sex, and race groups within offense categories (tables 1, 3, 4, 5 and 6) and changes in arrest rates by offense and demographic groups (table 7). The report also contains graphs displaying trends in arrest rates for individual offenses between 1990 and 2010 and graphs of age-specific arrest rates for 1990, 2000 and 2010. These figures show changes in arrest rates and provide insight into the flow of individuals into the criminal justice system over time."
