The Salvation Army has functioned successfully for more than a century. Its outreach has expanded to include 106 countries where the Gospel is preached in 160 languages. Throughout, the basic social services developed by William Booth have remained and new programs that address contemporary needs have been added. Among these are disaster relief services, day care centers, summer camps, holiday assistance, services for senior citizens, housing for the homeless, family and career counseling, correctional services, and drug rehabilitation.
