Housing conditions are often used as indicators of income due to the level of household resources that are used in acquisition of homes and in repairs and maintenance of dwelling units. Housing conditions have implications for provision of other services such as connections to water supply, electricity, and waste disposal and other sanitation services. Low provision of these essential services leads to higher incidence of diseases, fewer opportunities for business services, and lack of a conducive environment for learning. Materials used in the construction of dwelling units are an indicator of housing conditions and the extent to which they protect occupants from the elements and other environmental hazards. Availability of materials, costs, weather and cultural conditions have a major influence on the type of materials used in different localities.
