Housing refers to a multi-dimensional concept relating to the process of residing and the objects of dwelling whose main attributes are location relative to access to livelihood, tenure arrangements, cost and physical structure, as well as their environment. Housing is likewise a physical structure as well as a social structure, functioning at different spatial scales from homes, neighborhoods, communities, municipalities, cities, provinces, and regions. It is also a sector of the economy, an important category of land use in both urban and rural areas, especially in cities, and is an important factor in the overall dynamics of the urban system.
