How did sexism change between 1930 and 2012?

Between 1930 and 2012, sexism evolved significantly, reflecting broader societal changes. In the 1930s, traditional gender roles were predominant, with women largely confined to domestic responsibilities and limited access to education and professional opportunities. By 2012, the feminist movements and various social reforms had led to increased gender equality, greater representation of women in the workforce, and legal protections against discrimination. Despite these advancements, challenges like the gender pay gap and persistent stereotypes remained, indicating that while progress was made, the battle against sexism continued.
