Redistricting PA Supreme Court Signs Off on New State House, Senate Districts On March 16, 2022, the Pennsylvania Supreme Court gave its final approval to state legislative redistricting maps. The boundaries of state House and Senate districts, as well as U.S. congressional districts, are redrawn every 10 years in conjunction with the U.S. Census to address shifts in population and meet the “one person, one vote” principle. Barring further legal challenges, these are the maps that will be in place when voters head to the polls on Tuesday, May 17. To view statewide maps for the House and Senate, visit here.
