*Does not include delegates.

1These numbers take into account Members who served in both the House and the Senate.

2Some of the larger States split into smaller States as the country grew westward (e.g., part of Virginia became West Virginia); hence some individuals represented more than one State in Congress.

3North and South Dakota were formed from a single territory on the same date, and they shared the delegates before statehood.

4The Territory Northwest of the Ohio River was established as a district for purposes of temporary government by the Act of July 13, 1787. Virginia ceded the land beyond the Ohio River, and delegates representing the district first came to the 6th Congress, March 4, 1799.
