From ThinkProgress:
Though Congress remains whiter, older, and more male than the nation as a whole, the incoming class will be the most diverse in history.
The 113th Congress will be more representative of the United States from race to religion, and from gender to sexual orientation. It will look more like America with 4 new African American representatives, 10 new Latinos, 5 new Asian Americans and 24 women in the House or Senate.* It will believe more like America with the first two Hindu congresspeople, the first Buddhist senator, and the first non-theist to openly acknowledge her belief prior to getting elected. It will love more like America, with 4 new LGBT congresspeople or senators, including the first openly bisexual congresswoman and the first openly gay congressman of color. And it will be younger, with four new congressmen born in the 1980s.
