Notes: The analytical samples include only those study participants who were in school at baseline because of a lack of data on skill levels at school leaving for those who left school prior to baseline. The analytical sample is also limited to those who had not yet experienced a first birth at baseline. There are further restrictions to the analytical sample by study: we exclude data on 1,312 males collected in MSAS because of the lower proportion of males experiencing a first reproductive event by Round 6 (39 % were ever married, and 34 % ever had a biological child) and because we wanted to ensure comparability across studies. We also exclude data on the sample of 10- to 14-year-old girls at baseline in AGEP because childbearing data were not collected until age 15. For each study, a small number of additional observations are excluded because of missing data. Data on the following eight household assets were collected across all three studies: mattress/cot/bed, table, TV, radio, mobile phone, bicycle, motorcycle, and electricity. This table includes the mean number of household assets in the analytical sample, of a total of these eight, by study.
