Additional Information

The Yemen Arab Republic Fertility Survey was carried out in the same areas as the 1975 census, thus covering about 94 per cent of the total population. The sampling frame was specially designed and made as much use as possible of existing administrative divisions. All households in selected clusters were interviewed. For the individual survey, clusters were divided into four subclusters; interviews were attempted with all eligible women in all households in one subcluster of each cluster. Female interviewers were used in selected subclusters; elsewhere, male interviewers were used. The achieved sample size for the individual survey is lower than expected because of flooding which resulted in failure to contact about 700 households.

The household schedule covers household amenities (including toilet, water, lighting and cooking facilities), mortality in the last 24 months and orphanhood questions, education and fertility. Comparison of household and individual survey data suggest appreciable omission of births from the former.
