From: Mapping changes in housing in sub-Saharan Africa from 2000 to 2015

Population Number of people Prevalence (%) of people living in houses built with finished materials (95% CI) Prevalence (%) of people living in improved housing (95% CI)
  2000 2015 2000 2015 2000 2015

Rural 500,865,953 728,908,071 25.6 (22.8–27.5) 44.7 (41.9–47.6) 8.2 (7.5–9.1) 18.4 (16.7–19.8)
  1. Predictions represent all countries in sub-Saharan Africa excluding South Africa, Comoros and desert areas. Houses were considered to be built with finished materials if at least two out of three parts of the structure (walls, roof and floor) were made of finished materials rather than natural or unfinished materials (Supplementary Text). Houses were considered to be ‘improved’ if they had all of the following characteristics: improved water supply, improved sanitation, three or fewer people per bedroom and house made of finished materials (Supplementary Information). CI, confidence interval.
