The 92nd United States Congress began on January 3, 1971. There were eight new senators (three Democrats, four Republicans, one Conservative) and 51 new representatives (31 Democrats, 20 Republicans) at the start of the first session. Additionally, five senators (four Democrats, one Republican) and 10 representatives (four Democrats, six Republicans), as well as one new delegate (a Democrat), took office on various dates in order to fill vacancies during the 92nd Congress before it ended on January 3, 1973.
Due to redistricting in New York, two representatives were elected from newly established congressional districts.
