What is an RRI?
” For this decision point, the RRI compares the arrest rate for white youth with the arrest rate for all racial minorities as a group (and for each racial minority group individually). To calculate an arrest rate (or any rate), you need a numerator and a denominator. Typically an arrest rate for a racial group uses a measure of their arrests in a year as the numerator and a measure of population as the denominator. Many arrest counts could be used depending on the process that one wishes to study (e.g., all arrests, violent crime arrests, drug arrests).
