Additional Information

The sample was based on the household listings prepared for Round III of the Survey of Population Change. Fieldwork occurred in two phases. In March and April 1985, male interviewers conducted a household enumeration and a survey of currently married husbands whose wives were aged under 50 years. In the second phase, which took place in April to June, ever-married women aged less than 50 years in the same sample of households were interviewed by female staff. A total of about 3300 interviews with husbands were completed, of which 2955 were manually matched to the information collected from the wife.

The questionnaire for women adhered strictly to the WFS core Mark 1. The data from the matched subsample of husbands are available on the SR file. They include: household income; a standard of living index; size of family enterprise (if any); husband's knowledge and use of contraception; fertility preferences; perceived advantages of large and small families; expectations of support from children; the financial burden of educating sons and daughters; child care arrangements if wife worked.

A community survey was conducted in rural areas. Detailed information on community development was collected: use of mechanical equipment for agriculture; accessibility of rice mills; nature of the agricultural labour force; marketing arrangements; the presence of manufacturing industries etc. Access to health and family planning facilities were also ascertained.
