The YMCA is a worldwide organization based in Geneva, Switzerland, with more than 57 million beneficiaries from 125 national associations.
Local YMCAs engage in a wide variety of charitable activities, including providing athletic facilities, holding classes for a wide variety of skills, and humanitarian work. The different local YMCAs are voluntarily affiliated through their national organizations. The national organizations, in turn, are part of both an Area Alliance and the World Alliance of YMCAs. The World Alliance's main motto is "empowering young people."
