The following description of this survey appeared in the 1991 edition of Dynamic Database: A Catalogue of Survey Data Files, Voorburg: International Statistical Institute.
Name of survey: Trinidad and Tobago Fertility Survey
Executive agency: Central Statistical Office
Date of fieldwork: 1977
Universe: All women 15-49 (except full time students aged 15-19)
Coverage: National, 100%
Contents: WFS Core Mark 1 + family planning module
Supplementary surveys: Household members (n = 21,588, weighted)
The sample frame was derived from the Continuous Sample Survey of Population
(CSSP): it was designed to be self-weighting, but weights were introduced to
adjust for variation in average household size. (Selection probabilities were
based on population size but actual selection was in terms of households.)
Interviewers usually administered the household schedule and the individual
questionnaire in a single visit. All women aged 15-49 who were not full-time
school students were eligible for interview.
In order to reconstruct a more adequate population base, a record for each
student (n = 626) is available on the SR file. These records contain only age,
residence details, and household variables.

expanded to include non-cohabiting relationships. A complete history of sexual
partnerships was obtained, with allowance for more than one type of
union/relationship with the same partner. Separate parallel histories of unions
and partners are preserved on the SR file.
The abortion module was used and a complete history of non-live births is
available on the SR file. Child care arrangements for working mothers were
