Notes: All results are weighted using provided sample weights. The sample includes women ages 15–49 (all countries) and men ages 15–59 (Burkina Faso, Cameroon, and Ghana), men ages 15–54 (Kenya), and men ages 15–49 (Tanzania). The wealth index is the fraction of nine assets or amenities that the respondent’s household has; the assets and amenities are radio, television, refrigerator, bicycle, motorcycle, car, telephone, electricity, and a flush toilet or pit latrine (must have nonmissing values for at least five components to be included). Rural is an indicator for whether the respondent currently lives in a rural area. Had premarital sex is an indicator for whether the respondent has had premarital sex; respondents who have not had intercourse are assigned a value of zero. Primary education, secondary education, and higher education are indicators for whether the respondent completed each level of schooling. Radio, television, refrigerator, bicycle, motorcycle, car, telephone, and electricity are indicators for whether the respondent’s household owns or has these amenities. Toilet is an indicator for whether the respondent’s home has a flush toilet or pit latrine. The transfusion data are from Tanzania.
