This is a map of estimated durable housing in the world. A durable dwelling is a structure that has been designed to last for many years. To live in a structure that is not durable suggests increased levels of insecurity for the inhabitants. Their home will be more likely to be damaged by inclement weather conditions, their legal right to live there may not be well established, and the housing itself likely to lack the facilities of a more permanent structure.
Most people in most regions have access to durable dwellings. However, in Southeastern Africa only 29% of the population live in permanent structures. In Chad not even 3% of people have such housing security.
