The district you live in depends on if you are looking at the city, state, or federal level. The district lines for the U.S. Congress is different from that of the state House and Senate or Philadelphia’s City Council. The city of Philadelphia is also divided into 66 wards which are each split into 1,692 divisions.
Philadelphia’s political boundaries change with the city. Specifically, the Census is used to help determine different districts.
The current U.S. congressional districts were redrawn after the PA Supreme Court ruled that the districts drawn using the 2010 Census were unconstitutional. The next redistricting will occur following the 2020 Census, and those districts should take effect for the 2022 congressional elections.
The current state House and Senate districts were drawn by the General Assembly and approved by the Governor following the 2010 Census. New districts will be drawn after the 2020 Census and should take effect for the 2022 elections.
Philadelphia City Council districts are also based on the 2010 Census and will be redrawn by City Council after the 2020 count. Those new districts should be in place for the 2023 Council elections.
