Trinidad & Tobago, 1977 (WFS)

The following description of this survey appeared in the 1991 edition of Dynamic Database: A Catalogue of Survey Data Files, Voorburg: International Statistical Institute.

Basic Information

• 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%
• Size: 4355
• Weights: Weighted
• Contents: WFS Core Mark 1 + family planning module
• Supplementary surveys: Household members (n = 21,588, weighted)

Additional Information

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.

As in most other WFS Caribbean surveys, the union (marriage) history was 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 elicited.

The income of the current partner and general household income is recorded. Household survey data on dwelling type size and ownership, on water supply and lighting and on ownership of household facilities have been transferred to the SR file.
