In 2018, Alexandria Ocasio-Cortez of New York, Ilhan Omar of Minnesota, Ayanna Pressley of Massachusetts, and Rashida Tlaib of Michigan were elected to the US House of Representatives. All of these women were under 50 and came from diverse backgrounds.

The election of these four women brought more young people and people from diverse backgrounds into the House of Representatives. This means representation for underrepresented groups increased. The question does not show that representation for their states increased, since each state’s representation is based on its number of House seats.
