Down and out in New York and London: a cross-national comparison of homelessness.

The results indicate that characterizations of homelessness as a trait rather than a state reflect the tensions between social justice, public concepts, and a nation's economic resources. The absolute numbers of homeless persons, including those who are mentally ill, primarily reflect structural factors such as the availability of low-cost housing and public benefits. The commonalities that mentally ill homeless persons share with other vulnerable groups generally outweight their differences. The statutory rights to entitlements may be vitiated in times of shortage, especially for the least capable citizens. In both countries, efforts have been made to use the voluntary sector to serve the homeless, although it has been used much more extensively in Britain.
