The lives of American women changed significantly in the 1920s due to new technologies and social norms: 1) Labor-saving devices like vacuum cleaners and washing machines freed up women's time enabling new leisure activities and independence. 2) Widespread car ownership made it easier for women to socialize outside the home. 3) The "flapper" ideal of the 1920s represented a new social freedom for women through behaviors like drinking, smoking, and dating without chaperones. However, changes were not experienced equally and traditional roles remained important for many women, especially in rural areas.
