The major addition to the WFS core questionnaire is a detailed month-by-month
sexual life history for the twelve months preceding the survey (see also

(if any) prior to conception; the number of months using specific methods, the
number of months without sexual intercourse and the reason (celibacy, marital
dissolution, temporary absence of spouse, illness, other). From these data,
various measures of contraceptive effectiveness can be derived.
