How were the data sources used to calculate the formula selected?
OJJDP, in conjunction with the Bureau of Justice Statistics (BJS) and the Justice Research and Statistics Association (JRSA), attempted to identify the most recent and accurate data for use in the formula calculation. The sources and calculations explained in the Methodology section of the Web site were deemed to be the most accurate by the agencies involved. OJJDP has provided funding to JRSA to continue to examine these data sources and look for ways to improve the accuracy of the formula calculations.
