A Scout is a child, usually 10–18 years of age, participating in the worldwide Scouting movement. Because of the large age and development span, many Scouting associations have split this age group into a junior and a senior section. Scouts are organized into troops averaging 20–30 Scouts under the guidance of one or more Scout Leaders or Scoutmasters. Troops subdivide into patrols of about 6–8 Scouts and engage in outdoor and special interest activities. Troops may affiliate with local, national, and international organizations. Some national Scouting associations have special interest programs such as Air Scouts, Sea Scouts, outdoor high adventure, Scouting bands, and rider Scouts. In the USA there was around 6 million scouts in 2011.

Scouting, also known as the Scout Movement, is a worldwide youth social movement employing the Scout method, a program of informal education with an emphasis on practical outdoor activities, including camping, woodcraft, aquatics, hiking, backpacking, and sports. Another widely recognized movement characteristic is the Scout uniform, by intent hiding all differences of social standing in a country and encouraging equality, with neckerchief and campaign hat or comparable headwear. Distinctive uniform insignia include the fleur-de-lis and the trefoil, as well as merit badges and other patches.
