75th United States Congress

[a] The apportionment of seats in the House of Representatives was based on the 1930 United States census.

Both chambers had a Democratic supermajority, with the party increasing their majority in both the House and Senate, and with the reelection of President Roosevelt, maintained an overall federal government trifecta.

[1][2] This is the most recent Congress to feature a 3/4th majority in the House or Senate by either party.

Senators are popularly elected statewide every two years, with one-third beginning new six-year terms with each Congress.

The names of members of the House of Representatives are preceded by their district numbers.
