Homelessness prevention policy in an international context : The Housing Act (Wales) 2014

A review article preceding a series of articles in this special issue considering specific aspects of the impacts and implementation processes of the Welsh legislation – we contextualise the introduction of the prevention agenda in Wales by defining homelessness and highlighting the shift towards prevention policy in an international context. We consider the nature of prevention, and examine related theoretical debates, critiques and the cost/benefits of prevention. We conclude by offering some reflections on the progress of homelessness prevention since the Act’s implementation drawing on data from the longitudinal post-implementation evaluation of the Housing Act (Wales) 2014
