Exposure status (definition 2) reclassifies variable V623, using a more liberal definition of infecundity. There are two differences between this definition and the definition used in V623:
1) For Model "B" countries, it is only possible to say that a women had been continuously married throughout the preceding five years if she was in her first union. This definition has been relaxed in V625, such that the respondent need only have been first married at least five years ago, and not necessarily continuously married throughout the last five years. For Model "A" countries, there is no change to this part of the definition.
2) Two additional variables have been used to declare a woman infecund. If the respondent said she cannot get pregnant when asked about preferences for additional children (V602 = 5), or if she reported that she was menopausal or had a hysterectomy when giving the reason she was not currently using a contraceptive method (V376 = 14), the respondent is coded as infecund.
