This article discusses the particular characteristics of men with schizophrenia or personality disorder and it compares these two categories with one another and with the destitute population as a whole. On a number of variables, no significant differences are discerned, the category as a whole sharing a background of considerable material and social deprivation. However, with reference to place of birth, loss of mother, and father's occupation, significant differences do appear. The two categories also show distinctly different patterns in the process of becoming destitute and they use existing agencies differently. Finally, the type of service most suitable for these men is discussed together with other issues raised by the question, ‘How can we improve the lot of the homeless single person?’
