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

With the reelection of President Franklin D. Roosevelt to a then record third term, the Democrats maintained an overall federal government trifecta.

This was the first Congress to have more than one Senate president (John Garner and Henry Wallace) due to the passage of the 20th Amendment in 1933.

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

Currently, this is the second and last Congressional session in which Wyoming sent 3 democrats to Congress (senators Joesph C. O'Mahoney and Harry Schwartz, as well as representative at-large John J. McIntyre).
