Jail populations continue to be under-evaluated and under-researched. While there is a plethora of research on correctional incarcerated populations, there is a need to better assess jail populations as more people interact with these institutions. To evaluate and research this population, the Washington Statistical Analysis Center (SAC) applied for and received the 2021 State Justice Statistics (SJS) grant from Bureau of Justice Statistics (BJS). Under this grant from BJS, the SAC will draw on the Washington Association of Sheriffs and Police Chiefs (WASPC)'s Jail Booking and Reporting System (JBRS) to evaluate the potential demographic disparities by rates of days in jail and by rates of recidivism. Main conclusions: 1. The proportion of jailed individuals who spent an above average number of days in jail during their initial booking was higher for males, higher for individuals who were part of the BIPOC community and decreased with an increased age of 36 years of age and older. 2. On average, male jailed individuals who recidivated had more days in jail for their initial booking. And, on average, non-BIPOC jailed individuals who recidivated had more days in jail for their initial booking than BIPOC jailed individuals who recidivated. 3. The proportion of jailed individuals who spent an above average number of days in jail following recidivism was higher for males, and BIPOC jailed individuals who recidivated had more days in jail following recidivism. Age did not impact the number of days in jail following recidivism.
