collectively designated as a Cub Scout pack, Boy Scout troop, Venturing crew, or Sea Scout ship. Each chartered organization may charter as many units as it wishes, but usually only 3 or 4 (one unit for each program level). The BSA council provides the leader training, inter-unit activities, camping programs, volunteer and professional support, and insurance coverage. Units also create their own activities (such as monthly camping trips, outings, or service projects), and most meet weekly at the place of the chartered organization for youth to learn basic skill development and practice leadership in small groups known as dens and patrols. The Church of Jesus Christ of Latter-day Saints was the first partner to sponsor Scouting in the United States. It adopted the program in 1913 as part of its Mutual Improvement Association program for young men, and it was the largest single sponsor of Scouting until it ceased sponsoring Scouting units at the end of 2019. The BSA at its peak reportedly had 4.8 million members in the 1970s with its membership plunging to less than half across its 266 local councils; down from 2.9 million in 2006 to roughly 2.3 million youth members just over a decade later. Leadership All Scouting units above the Cub Scout pack (i.e. units serving adolescent Scouts), leadership of the unit comprises both adult leaders (Scouters) and youth leaders (Scouts). In fact, this is a critical component of the program. In order to learn leadership, the youth must actually serve in leadership roles. Adult leaders may be either men or women in all positions. A properly run Scouts BSA troop is run by the Senior Patrol Leader, who is elected by the troop, and their assistant, who may either be elected or appointed. These and the other youth leaders are advised and supported by the adult leaders. "Scouts are youth-led." Finance The National Council is incorporated as a 501(c)(3) non-profit organization and is funded from private donations, membership dues, corporate sponsors, and special events with total revenues of $237 million. In addition to donations from individuals, the BSA receives extensive donations from major corporations. In 2010, their top corporate donors were, in order, Intel, Emerson, Verizon, 3M, Bank of America, Wells Fargo, Pfizer, Valero, UPS, U.S. Bank, Eli Lilly, GE, and Monsanto.
