Notes: Models were estimated separately for each of the 91 surveys in the analytic sample, and control for age, number of living children, whether the respondent is currently pregnant, Muslim religion, marital status, educational attainment, literacy, and experience of child death, and knowledge of modern contraception. Wald Chi-square tests are used to compare across regions and time periods.

¹Because of the additional sample size reductions for ever use of contraception (excluding respondents who never had sex and surveys that do not provide information on use of contraception or prior sexual intercourse), a separate set of models were estimated for this variable, and all other results in Table 5 exclude this measure. These models predicting ever use of contraception do not include knowledge of modern contraception, due to issues of multicollinearity.
