U.S. government agency of volunteers, formed in 1961 by Pres.
John F. Kennedy . Its purpose is to assist other countries in their development efforts by providing skilled workers in the fields of education, agriculture, health, trade, technology, and community development. Volunteers are expected to serve for two years as good neighbours in the host country, to speak its language, and to live on a level comparable to that of the local residents. By the early 21st century, more than 165,000 volunteers had served in the corps.
