A gender role, or sex role, is a set of socially accepted behaviors and attitudes deemed appropriate or desirable for individuals based on their sex. Gender roles are usually centered on conceptions of masculinity and femininity, although there are exceptions and variations. The specifics regarding these gendered expectations may vary among cultures, while other characteristics may be common throughout a range of cultures. In addition, gender roles (and perceived gender roles) vary based on a person's race or ethnicity.Gender roles influence a wide range of human behavior, often including the clothing a person chooses to wear, the profession a person pursues, manner of approach to things, the personal relationships a person enters, and how they behave within those relationships. Although gender roles have evolved and expanded, they traditionally keep women in the "private" sphere, and men in the "public" sphere.Various groups, most notably feminist movements, have led efforts to change aspects of prevailing gender roles that they believe are oppressive, inaccurate, and sexist.
