*Limited, incomplete, or no data were reported by the District of Columbia, Florida, Illinois, and New York in the 2015 Uniform Crime Report. Data should be used with caution and should not be compared to other states or previous year data.

Note: Because the number of agencies submitting arrest data varies from year to year, users are cautioned about making direct comparisons between 2015 arrest totals and those published in previous years’ editions of Crime in the United States.
