Additional Information

This survey formed part of the National Integrated Sample Survey Programme and used the multi-purpose master sample frame. The entire North-Eastern Province and a few other districts, comprising an estimated 5 per cent of the total population, were excluded. In rural areas, the household sample was selected systematically from a complete enumeration of sample clusters which took place as part of the 1977 National Demographic Survey. In urban areas, a special listing was conducted. The questionnaire was available in eight local languages, plus Swahili and English. The fieldwork was carried out in three separate regional phases.

Although the full family planning module was not used, the following extra items were collected: knowledge, ever-use and use in last twelve months of family planning sources; travel mode and time to nearest source; nature of last source used, waiting time, whether satisfied and whether intends to re-visit; whether family planning use was considered in last twelve months.

Current marriages were classified into monogamous and polygynous, and number of co-wives and rank of respondent were ascertained.

The definition of female employment (ie work for money) deviated from the normal WFS treatment, which used a more liberal definition.

The household members file contains a detailed set of derived variables concerning household composition.
