Youth organizations in the United States are of many different types. The largest is the government run 4-H program, followed by the federally chartered but private Scouting movement groups: the Boy Scouts of America (BSA) and the Girl Scouts of the USA (GSUSA). Another somewhat smaller but co-ed Scouting derived group is Camp Fire. Other youth groups are religious youth ministries such as the evangelical Christian Awana, Seventh-day Adventist Pathfinders, and Assemblies of God Royal Rangers.
Smaller Scout-like groups include the Christian Trail Life USA for boys, American Heritage Girls for girls, the non-denominational co-ed Navigators USA and Baden-Powell Service Association, and pagan but non-discriminatory SpiralScouts International.
There are also two types of Masonic Youth groups called International Order of the Rainbow for Girls (IORG or just referred to as Rainbow), and Job's Daughters International (JDI). Both of these organizations have a background in the Christian Bible but you do not necessarily need to believe in God, just a supreme being. There are many different charities and service projects that are done throughout the year for those in need.
