Pennsylvania's at-large congressional district

The U.S. state of Pennsylvania elected its United States representatives at-large on a general ticket for the first and third United States Congresses. General ticket representation was prohibited by the 1842 Apportionment Bill and subsequent legislation, most recently in 1967.

Some representatives, including Galusha A. Grow, served at-large after 1842 (in Grow's case, it was from 1894 to 1903). This was allowed because Pennsylvania had received an increase in the number of its representatives yet its legislature didn't pass an apportionment bill during those years.

1789–1795: eight then thirteen seats
Representatives were elected statewide at-large on a general ticket. After 1795, most representatives were elected in districts. Occasionally, at-large representatives were also elected.

1873–1945
No at-large representatives were apportioned after the 78th Congress.
