For model "B" questionnaires the questions relating to contraceptive use since the last birth are not asked and thus the respondent cannot be categorized as having used a method since the last birth or having only used a method before the last birth. In countries using the model "B" questionnaire, all past users are given code 3. In countries using model "A" questionnaires, all women who have not used in the calendar are treated as past users and given code 3.
