Housing is a social determinant of health and this book aims to provide a concise source of the theory and evidence on safe and healthy housing to inform students, academics, public and environmental health practitioners, and policy-makers, nationally and internationally. The book reviews the functions of housing and its relationship with the health and well-being of residents. It examines the implications of failures to satisfy those functions, including the potential impact on individuals, households, and society. It assesses options directed at avoiding, removing, or reducing threats and at promoting healthy indoor environments, particularly for the most susceptible and vulnerable members of society. It is essential reading for students, academics, and professionals within the areas of environmental health, public health, housing, built environment, social policy, housing policy, health policy, and law.
