The basic type of housing in the rural areas is the hut, most commonly beehive shaped, made of strips of wood woven around poles, and now covered with tin (thatch has become scarce). The huts are generally not grouped into villages but are organized in groups on a family basis. Civil war has caused homelessness through displacement of residents and destruction of homes. In 2000, the total number of displaced persons was at about 800,000 people. A little over 300,000 were sheltered in regroupment camps. Foreign assistance programs for reconstruction and imporvements in housing are underway.
