During this Congress, Johnny Isakson retired for health reasons and Kelly Loeffler was appointed, which increased the number of women from 25 after the 2018 elections to 26.

[1][33][better source needed] The average age of Senators at the beginning of this congress was 62.9 years.

[34] There were 313 non-Hispanic white, 56 Black, 44 Hispanic, 15 Asian, and 4 Native American congress members.

[35] Two Democrats — Alexandria Ocasio-Cortez and Donna Shalala — were the youngest (30) and oldest (78) freshmen women in history.

[36] Freshmen Rashida Tlaib (D-MI) and Ilhan Omar (DFL-MN) were the first two Muslim women and freshmen Sharice Davids (D-KS) and Deb Haaland (D-NM) were the first two Native American women elected as well.

[32] With the election of Carolyn Maloney as the first woman to chair the House Oversight Committee,[38] women chaired a record six House committees in a single Congress (out of 26 women to ever chair House committees in the history of Congress), including House members Maxine Waters (Financial Services), Nita Lowey (Appropriations), Zoe Lofgren (Administration), Eddie Bernice Johnson (Science, Space and Technology) and Nydia Velázquez (Small Business), as well as Kathy Castor, who chaired the Select Committee on the Climate Crisis.

Lowey and Kay Granger were also the first women to serve as chair and ranking member of the same committee in the same Congress since the since-defunct Select Committee on the House Beauty Shop, which was chaired and populated entirely by congresswomen during its existence from 1967 to 1977.
