This survey represents a bridge between the two main components (developing
versus developed countries) of the WFS programme. Because Portugal is a low
fertility European country, the survey used the WFS core questionnaire Mark 2
as its departure point. As a survey in a country classified by the United
Nations as developing, it was eligible for external financial support and
technical co-ordination from WFS headquarters. The sample was based on the
National Master Sample. A household enumeration (response rate - 80 per cent)
was followed by detailed interviews with ever-married women. The refusal rate
for the individual survey was only 2 per cent. Fieldwork started in October
1979 and ended in July 1980 and was conducted by eight teams of female
interviewers. The long duration was caused by delays in funding and subsequent
attrition of field staff.
The individual questionnaire contains: a full pregnancy history; details of
contraceptive use and failure in each pregnancy interval; the classification
of each pregnancy as wanted or unwanted. Reasons for wanting or not wanting
more children were probed in detail.
The household file is in a non-rectangular format. A record for each household
is followed by records for each member.
Data may be used for academic research, provided that credit is given
