The rate of participation of women in the Olympic Games has been increasing since their first participation in 1900. Some sports are uniquely for women, others are contested by both sexes, while some older sports remain for men only. Studies of media coverage of the Olympics consistently show differences in the ways in which women and men are described and the ways in which their performances are discussed. The representation of women on the International Olympic Committee has historically run well behind the rate of female participation, and long missed its target of a 20% minimum presence of women on their committee. As of 2023, 41.1% of members are women.
Mixed-sex sports are individual and team sports whose participants are not of a single sex. In many organised sports settings, rules dictate an equal number of people of each sex in a team. Usually, the main purpose of these rules are to account for physiological sex differences. Mixed-sex sports in informal settings are typically groups of neighbours, friends or family playing without regard to the sex of the participants. Mixed-sex play is also common in youth sports as before puberty and adolescence, sport-relevant sex differences affect performance far less.
