Young women are more liberal than they have been in decades, according to a Gallup analysis of more than 20 years of polling data.

Over the past few years, about 4 in 10 young women between the ages of 18 and 29 have described their political views as liberal, compared with two decades ago when about 3 in 10 identified that way.

For many young women, their liberal identity is not just a new label. The share of young women who hold liberal views on the environment, abortion, race relations and gun laws has also jumped by double digits, Gallup found.
