Additional Information

This survey was based on a subsample of the National Household Survey. The household schedule included information about births and deaths in the preceding 12 months, household amenities and place of birth of each member. Unusually detailed employment data were collected for adult members: whether currently working, occupation and work status, and size of landholding and agricultural assets.

The individual survey was conducted at the same time as the household survey by the same interviewers on a subsample of one woman in two aged 20-49 who were @de jure@ household members.

Supplementary contraceptive information collected in the individual survey includes: knowledge of supply source; travelling time to nearest source; ever-use and use last year of source; intention to re-use source and reasons for lack of intention.

A respondent's migration history was collected, but only the number of places of six or more months residence is available on the SR file. Respondent's and husband's income (plus area of land owned) was ascertained. Available on the SR file are household survey data concerning the presence of electricity, piped water, toilet facilities, consumer durables and details of dwelling construction. A complete history of non-live births is on the SR file. Various health care items concerning the last birth/pregnancy were collected: medical attention at and place of delivery; timing of first consultation; any reasons for failure to vaccinate last child.

A community survey was conducted in both urban and rural areas. Information was collected about number of inhabitants, Government services and main economic activity. The community data file is not held by the DDB.
