In 2000, there were about 1.3 million housing units nationwide. Though the government has encouraged privatization of housing and individual home ownership. Most residents, particularly in urban areas, find home ownership to be far too expensive in a poor economy. The existing housing stock is in serious disrepair. Most structures were built before 1980 and maintenance has been poor. Only about 28.9% of all dwellings have an indoor bathroom; only 31% have access to a sewage system. About 62% of all households use wells as a primary source of water. In 1999, only 2,900 structures were completed. Most new housing is built with brick or stone and concrete frames.
