^*Data were obtained from 40 Demographic and Health Surveys during 2001–2011. PR = prevalence ratio; CI = confidence interval.

^†Reference category is those that use a not shared facility.

^‡Adjusted for type of facility (flush toilet, improved latrine, unimproved latrine) mother's age, mother's education, highest level of education in the household, and ownership of assets.

^§West Africa is defined as Benin, Burkina Faso, Cameroon, Ghana, Guinea, Mali, Nigeria, Senegal, and Sierra Leone.
