Data sources

Demographic data are provided by the US Census and retrieved by the Census API. The chart combines race and Hispanic origin, which are asked as two separate questions on the Census. This means that totaling up the numbers shown may not equal the city or county’s population total because people who identify as Hispanic or Latino may also identify as one of the other non-White race categories.

Law enforcement data are provided by the Federal Bureau of Investigation’s Uniform Crime Reporting (UCR) Program. Not every city/county is represented in this data, and the FBI makes the following recommendation:

Because of law enforcement’s varied service requirements and functions, as well as the distinct demographic traits and characteristics of each jurisdiction, readers should use caution when drawing comparisons between agencies’ staffing levels based on police employment data from the UCR Program. In addition, the data presented here reflect existing staffing levels and should not be interpreted as preferred officer strengths recommended by the FBI. Lastly, it should be noted that the totals given for sworn officers for any particular agency reflect not only the patrol officers on the street, but also the officers assigned to various other duties such as those in administrative and investigative positions and those assigned to special teams.
