Imputation and derivation

Derivation

Calculated from the birth history of the mother's questionnaire. If the mother was not interviewed, this is set to "missing". If the mother was interviewed, set to "notappl" if the child is first-born; otherwise, it is the number of months between this child's date of birth and the next-older child's date of birth.
