It met in Washington, DC from January 3, 1969, to January 3, 1971, during the first two years of the first administration of U.S. President Richard Nixon.

The apportionment of seats in this House of Representatives was based on the Eighteenth Census of the United States in 1960. Both chambers had a Democratic majority.
