The homeless are a remarkably diverse group of people that come from all walks of life. They are made up of men & women, single persons & families, young & old people, those with and without mental and physical health problems, rural and urban dwellers, the rich and poor, people with high and low educational and occupational statuses, and racial, ethnic and visible minorities. Illegal immigrants, former criminal offenders, runaway youth, prostitutes, and people with drug and alcohol addictions also contribute to the composition of the population (Varney & Vliet 2008; Chamberlain & MacKenzie 2006; Zald 2004; Burt 1993; Rossi 1989).
