The sample sizes are presented for the columns ‘Overall’, ‘Female’, ‘Male’, ‘10–17’, and ‘18–24’. The ‘Prevalent cases’ and ‘New infections’ columns show the number of cases. The male and female numbers are aggregated across all age groups, while the numbers for each age group represent both sexes. In the analysis, a few countries (Ethiopia, Côte d’Ivoire, Tanzania) with no available data on early sexual activity in the age group 10–14 are excluded from modeling. Rwanda has a different weighting scheme, and thus not included in modeling
