What is one significant impact of world war 1 on American women?

"The period from 1890 through 1920 was known as the Progressive Era in America, an age of increased industrialization and production. Social problems such as labor conditions for children and women, and public health and safety, became prominent national issues. To address some of these social issues, women's clubs and organizations-like the Young Women's Christian Association (YWCA) and the national General Federation of Women's Clubs (GFWC) - were formed. The National Association of Colored Women was organized to respond to racism and other social issues impacting African-American women and their families."

One significant impact is it allowed women to have the opportunity to be able to have a job which led to today world where most women have jobs in america now.
