Age at first sexual intercourse - imputed. This is the same as MV525, except for respondents who reported that their first sexual intercourse was at the time of their union. For these cases, the age at first sex is taken from the age at first union. In cases where the age at first sex was inconsistent with the age at conception of the first child, but only by one year (V532 = 3), the age at first sex was reduced by one year, consistent with the "Rule of one" applied in DHS I which is the correction of the data if the error is no more than a month. Other cases flagged as inconsistent on variable V532 (codes 1, 2, 4, 5) are recoded as 97 (inconsistent). Cases coded 6 on V532 are not changed.
