After receiving complaints regarding conditions inside Philadelphia Department of Prisons’ facilities, the Office of the City Controller conducted a review of operational issues, including overall staffing levels, inmate population, leave usage and attrition rates, using data provided by Prisons in an attempt to improve safety for correctional officers and inmates. Overall, the Controller’s Office found that while the inmate population decreased slightly since Fiscal Year 2019 (FY19), correctional officer vacancies tripled and prisons’ conditions declined.
