Total number of eligible women indicates the number of women found eligible for the individual survey in the household schedule. The eligibility criteria are generally: female, aged between 15 and 49. In some countries, the eligibility criteria restricts the survey to ever-married women. In early DHS II surveys, the eligibility criteria also required that the members slept the previous night in the household. In later surveys, this criteria was dropped and all usual residents and visitors who slept in the household the previous night were interviewed. Non de facto women were later dropped in the analysis and do not appear in the Individual Recode Data File.
