Plural district

A plural district was a district in the United States House of Representatives that was represented by more than one member. States using this method elected multiple members from some of their geographically defined districts. They did so on a single ballot (block voting) or on separate concurrent ballots for each seat (conducting multiple plurality elections). In more modern terms, for less ambiguity, such a district is termed a multi-member district (such as many of those of the New Hampshire House of Representatives, abroad and in other bodies).

Such greater than one-member district magnitude was used to give more populous counties or established Congressional Districts fair representation without redistricting (specifically, dividing them). It was rare before 1805 but notably applied to many Congressional Districts of New York and Pennsylvania until federally (nationally) prohibited by the 1842 Apportionment Bill and consequent locally implementing legislation.
