Founded in 1844, YMCAs collectively make up the largest nonprofit community service organization in America. YMCAs are at the heart of community life in neighborhoods and towns across the nation. They work to meet the health and social service needs of 16.9 million men, women and children. Ys help people develop values and behavior that are consistent with Christian principles and are for people of all faiths, races, abilities, ages and incomes. No one is turned away for inability to pay. YMCAs' strength is in the people they bring together. In the average Y, a volunteer board sets policy for its executive, who manages the operation with full-time and part-time staff and volunteer leaders. Ys meet local community needs through organized activities called programs. In its own way, every Y nurtures the healthy development of children and teens; strengthens families; and makes its community a healthier, safer, better place to live. YMCA programs are tools for building the values of caring, honesty, respect and responsibility. Longtime leaders in community-based health and fitness and aquatics, Ys teach kids to swim, offer exercise classes for people with disabilities and lead adult aerobics. They also offer hundreds of other programs in response to community needs, including camping, child care (the Y movement is the nation's largest not-for-profit provider), teen clubs, environmental programs, substance abuse prevention, youth sports, family nights, and job training.
