From WHYY in Philadelphia:

“The commission in charge of redrawing Pennsylvania’s House and Senate maps has voted 3-2 to make a major change to the redistricting process: It will no longer count many state prisoners as residents of the districts where they’re incarcerated, but rather as residents of the districts where they originally lived.

. . . .

It fell to the committee’s court-appointed tiebreaker, longtime University of Pittsburgh law professor Mark Nordenberg, to make the decision. He noted that this is a big change in a redistricting process already marred by late census data, and the logistics will be time consuming and tricky. But ultimately, he voted for change.”

The decision does not affect federal election districts.
