This paper investigates this bias using calendar data from the Demographic and Health Surveys. The paper presents unadjusted and adjusted 12-month failure rates for each of nine countries. The impact of redundant use on failure rates is generally modest. It tends to be greater in Indonesia, however, where both the incidence and the duration of overlap are relatively large.
