The apportionment of seats in the House of Representatives was based on the 1970 United States census.

Members of the House of Representatives are listed by their district numbers.

There were 4 deaths, 4 resignations, one declared vacancy, and one party change.

Lists of committees and their party leaders for members of the House and Senate committees can be found through the Official Congressional Directory at the bottom of this article.

The directory after the pages of terms of service lists committees of the Senate, House (Standing with Subcommittees, Select and Special) and Joint and, after that, House/Senate committee assignments.
