The Girl Scouts of the United States of America (GSUSA) is a youth organization for girls in the United States and American girls living abroad. The Girl Scout program developed from the concerns of the progressive movement in the United States from people who sought to promote the social welfare of young women and as a female counterpart to the Boy Scouts of America. It was founded by Juliette Gordon Low in 1912 and is based on the Scouting principles developed by Robert Baden-Powell. The GSUSA uses the Scout method to build self-esteem and to teach values such as honesty, fairness, courage, compassion, character, sisterhood, confidence, and citizenship through activities including camping, community service, learning first aid, and earning numerous badges that can teach lifelong skills. Girl Scouts are recognized for their achievements through rank advancement and various special awards. GSUSA has programs for girls with special interests, such as water-based activities. Membership is organized according to age levels with activities appropriate to each age group.
