City of PhiladelphiaView metadata for key information about this dataset. The PSA boundaries replaced a much smaller boundary, Sectors in 2009. In several Districts, PSA's split Sector boundaries and therefore a historical comparison would not necessarily be accurate. These polygon features were created by the Crime Mapping & Analysis Unit and they represent an initiative by the Philadelphia Police Department that started in 2009. A Police District can have up to 4 PSA's and as few as 2. There is a Police Lieutenant assigned to each PSA and officers are limited to patrol their specific boundary with the goal of familiarity with the area residents and businesses.
