Table 1: Share of dwelling types in Uganda (UBOS 2010). Dwelling Types Year 2009/10 Urban (%) Rural (%) Uganda (%) Detached 30.2 64.4 57.9 Huts 6.2 25.1 21.5 Tenements 58 9.2 18.4 Others 5.7 1.4 2.2 Moreover, in 2010, around 62% of urban and 42% of rural families used only one room for sleeping (UBOS 2012). Considering the average household size of 5 people (3.9 people in urban and 5.2 persons in rural areas) (UBOS 2010), it could be argued that the number of sleeping people in almost half of Ugandan households is 4 or more people which is considerably more than the international standards. Such conditions could greatly affect the health and wellbeing of the occupants contributing to issues such as poor indoor air quality and increased risk of infectious and transmissible diseases (UBOS 2012). Table 2 below shows the average household size and the number of rooms used for sleeping in urban and rural areas of Uganda. According to these data, it could be argued that there is a tangible transition of material use in Ugandan rural and urban housing, where the growing demand is towards iron sheet roofs and brick walls for construction of houses.

In 2010, around 62% of homes in Uganda (84% in urban areas and 57% in rural areas) were roofed with iron sheets (Figure 2) followed by thatched roof which took a share of 37%. Around 57% (84% urban and 51% rural) of all dwellings had brick walls and 39% (12% urban and 46% rural) were made out of mud and poles. More than 71% of floors were made from earth (25% urban and 82% rural) and 27% (71% urban and 17% rural) were covered with cement (NPA 2010; UBOS 2010).
