The Boy Scouts of America is one of the largest scouting organizations and one of the largest youth organizations in the United States, with about 1.2 million youth participants. The BSA was founded in 1910, and since then, about 110 million Americans have participated in BSA programs. BSA is part of the international Scout Movement and became a founding member organization of the World Organization of the Scout Movement in 1922. The stated mission of the Boy Scouts of America is to "prepare young people to make ethical and moral choices over their lifetimes by instilling in them the values of the Scout Oath and Law." Youth are trained in responsible citizenship, character development, and self-reliance through participation in a wide range of outdoor activities, educational programs, and, at older age levels, career-oriented programs in partnership with community organizations. For younger members, the Scout method is part of the program to instill typical Scouting values such as trustworthiness, good citizenship, and outdoors skills, through a variety of activities such as camping, aquatics, and hiking. To further these outdoor activities, the BSA has four high-adventure bases: Northern Tier, Philmont Scout Ranch, Sea Base, and Summit Bechtel Reserve, as well as nearly one hundred separate camps and reservations specifically dedicated to scouts.
