What is the Indicator-Level Score?
What Did We Find?
When calculated using population as the denominator, Blacks are three times as likely as both Whites and Hispanic/Latinx to experience officer use of force. When calculated using arrests as the denominator, Hispanic/Latinx become the most disadvantaged group, at a rate 2 ½ times that of Blacks and 3 ½ times that of Whites; using this methodology, Blacks are 50% more likely to experience use of force as Whites in Tulsa.
What Data Source(s) were Used?
Tulsa Police Department, Internal Affairs 2016 & 2017 Annual Reports; U.S. Census Bureau, 2016 & 2017 American Community Survey, 1-Year Estimates
A use of force rate can be calculated in a number of different ways. Equality Indicators calculates the rate using total population as the denominator (as shown above). The Tulsa Police Department uses arrest rates as the denominator. However when analyzing community-wide data, this can be misleading because it excludes contacts with police that do not result in arrest, and may skew results to mirror disparities in arrest rates. In alignment with the mission of Equality Indicators, using population as the denominator more accurately reflects the overall social and public health impact of use of force on the entire community. However, because the Tulsa Police Department calculates its use of force rates by using total number of arrests as the denominator, we are including those rates here for reference. In 2017, the rates of officer use of force per 1,000 arrests by race in Tulsa are:
- Black: 33.1 incidents of use of force/1,000 Black arrests
- Hispanic/Latinx: 80.1 incidents of use of force/1,000 Hispanic/Latinx arrests
- White: 23.2 incidents of use of force/1,000 White arrests
- Native American: 18.4 incidents of use of force/1,000 Native American arrests
- Both arrests and use of force incidents for the Asian population are too small to be statistically valid.
