The policy convergence between the national strategies for mental health and for homelessness in Ireland in recent years is a striking development, involving as it does a unified perspective on the housing-led approach as a key both to mental health recovery and to sustainable exits from homelessness. The largely successful operation of the Irish welfare state safety net partially explains the very low levels of =roofless' and =houseless' homeless persons. This chapter presents descriptive data on both people that are homeless and those that are at risk of homelessness. An examination of the emerging policy focus on homelessness is followed by a listing of the challenges of realising the policy aspirations of secure, suitable and affordable housing for all persons with mental health disabilities who are homeless or at risk of homelessness.
