The 250 enumeration areas (EAs)of the Nigeria Fertility Survey are a subsample
of the EAs used for the National Demographic Sample Survey 1980. It was
originally intended as a self-weighting sample but problems of implementation
led to the abandoning of this. The final sample includes weights to allow for
the unequal probabilities of selection. The household and individual interviews
were conducted on the same visit by the same (female) interviewers. The
questionnaire was translated into six languages.
The household schedule ascertained the basic characteristics of the household
members together with the environmental conditions of the house and information
on possessions. A detailed set of derived household composition variables have
been added to the file.
As in the Benin WFS survey, a modification of the FOTCAF module was used,
whereby: (1) information was gathered about live-birth rather than pregnancy
intervals; (2) provision was made to record information about the third to last
interval, if this interval started within the five years preceding the survey.
The latter amendment removes much of the selection bias inherent in the
standard FOTCAF module which is restricted to the last and last-but-one
