New District Map Every 10 years, the boundaries of Pennsylvania’s House and Senate districts are redrawn to reflect changes in population. The Pennsylvania Constitution requires the state’s 50 Senate districts and 203 House districts to be “as nearly equal in population as practicable.” Using data collected in the 2020 U.S. Census, the state’s Legislative Reapportionment Commission developed, and the state Supreme Court gave final approval to new legislative districts. Rep. Wentling is among those residents who are changing districts, as his home will now be located in the new 7th District. The new district maps do not become official until Dec. 1, 2022. However, all forthcoming elections for the General Assembly from now until the next reapportionment in 2032 will use the new district lines.
