* Party division totals are based on November election day results. The actual party division of a particular Congress often changes due to the death or resignation of a Member, contested elections, or changes in Member party affiliations. 1 Before the first day of Congress, 14 representatives-elect died. The results of the special elections caused party control of the House to change and Democrats organized with the majority of the House seats.
