Summer camp is a supervised program for children and/or teenagers conducted (usually) during the summer months in some countries. Children and adolescents who attend summer camp are known as campers.The traditional view of a summer camp as a woodsy place with hiking, canoeing, and campfires is evolving, with greater acceptance of newer summer camps that offer a wide variety of specialized activities. For example, there are camps for the performing arts, rock music, magic, computers, children with special needs, and weight loss. In fact, the American Camp Association reports that in 2006, 75 percent of camps added new programs. This is largely to counter a trend in decreasing enrollment in summer camps, brought about by smaller family sizes, the growth in supplemental educational programs and the popularity of electronic media, all of which have made keeping children inside and occupied much easier than in previous generations.There are also religiously-affiliated summer camps, such as those run by Jewish organizations and by Evangelical Christian groups.The primary purpose of many camps is educational or cultural development. A summer camp environment may allow children to take healthy risks in a safe and nurturing environment.
