Some statistical analysis issues at the World Fertility Survey.

"The World Fertility Survey carried out cross-sectional probability surveys of fertility in more than 40 developing countries between 1972 and 1984. Statistical issues in regression analysis of the data are reviewed, including treatment of interactions, the selection of regressor variables, and appropriate linear models for rate variables. Similar issues arise in many other applications of regression to observational data."

The exclusion of never-married women from Chinese fertility surveys.

Never-married women have been regularly excluded in official national surveys of fertility in China, even in light of evidence of increasing premarital sexual activity. Likewise, never-married women in the United States were consistently excluded from national fertility surveys prior to 1982 because of the perceived sensitivity of questions about contraceptive use and sexual activities. Data on sexual and fertility behavior from all women of reproductive age, regardless of marital status, can provide direct measures of sexual activity and unintended pregnancies, as well as facilitate modeling of social networks underlying the sexual transmission of diseases. China's need for such information, however sensitive, will become more difficult to ignore given increasing pressures to attend to the health needs of their never-married but sexually active population.

Fertility and family planning in Jordan: results from the 1985 Jordan Husbands' Fertility Survey.

The 1985 Jordan Husbands' Fertility Survey (JHFS) was designed to assess husbands' attitudes and behavior toward fertility and family planning. The 1985 JHFS was a follow-up survey to obtain data from husbands of women who were currently married in the 1983 Jordan Fertility and Family Health Survey (JFFHS). The results from the 1985 JHFS point to the usefulness of collecting fertility and family planning information from husbands. These findings showed that nearly 40 percent of the husbands do not believe in practicing contraception, and more than 50 percent of the husbands report that family size should be "up to God." How program officials address these issues will be important for the future success of the family planning program in Jordan.

The contribution of the World Fertility Surveys to an understanding of the relationship between women's work and fertility.

A consistent negative association between women's paid work and fertility in developed countries has emerged from many years of research. Results from research in developing countries are more ambiguous, with as many examples of a positive association as of a negative one. Lack of data comparability has often hampered interpretation of results. The World Fertility Surveys (WFS)--undertaken in 40 developing countries between 1974-81, using a common core questionnaire that included numerous questions on women's work--have created a unique opportunity to evaluate this association in a comparative framework. This article reviews and interprets the major findings on the work-fertility relationship from this and other published research on women's work and fertility, and assesses the data limitations. The article concludes with recommendations for the treatment of women's work in the design of future fertility and family planning surveys.

The World Fertility Survey: an appraisal of methodology.

"In the first half of the article, a broad account of content and procedures is given. In conduct of individual surveys, the achievements of the World Fertility Survey were based on thoroughness rather than technical superiority. The later aspects of the program, including analysis, archiving, and data dissemination, were more innovative and represent models of excellence for similar future enquiries. In overall terms, the program is judged to be an expensive success. In the second half of the article, two methodological issues are discussed in more detail: the collection of retrospective birth histories and the translation of survey instruments into local languages." Comments by Anthony G. Turner (pp. 768-9), Kweku T. de Graft-Johnson (pp. 769-70), Burton Singer (pp. 771-2), and Joel E. Cohen (pp. 772-4) are appended.

Homogeneity in Turkish Fertility Survey: implications for cluster size derived from homogeneity in basic survey variables.

"This study examines several error statistics derived from the computed variance in basic survey variables of the Turkish Fertility Survey (1978). These are standard error, design factor, design effect and rate of homogeneity. [The] results are presented for the total sample as well as for subclasses. [It is demonstrated that] previous knowledge about the homogeneity and cluster size of main survey variables [will help] to design better surveys in the future. This process can be further extended for other survey variables by imputation." (summary in TUR)

The World Fertility Survey and Contraceptive Prevalence Surveys: a comparison of substantive results.

This paper deals with the findings of the World Fertility Survey (WFS) and Contraceptive Prevalence Surveys (CPSs) in five areas of common interest: fertility, contraceptive use, measuring the effect of the availability of contraceptives on levels of use, the unmet need for family planning services, and breastfeeding. The comparisons have several implications for those designing surveys of fertility and family planning in developing countries, among them, that women should be asked for the dates of at least their last two births (not just the last birth as in the CPSs) in order to ensure accurate estimates of fertility and duration of breastfeeding.

Collecting data on pregnancy loss: a review of evidence from the World Fertility Survey.

Estimates of levels and differentials of pregnancy loss are presented for 40 developing countries participating in the World Fertility Survey (WFS) program. Judged against agreed-upon levels of spontaneous loss in human populations, WFS surveys measured from 50 to 80 percent of recognizable losses. The coverage of induced abortions appears to be much worse. Consistent with data from other sources and settings, the probability of loss is strongly correlated with maternal demographic characteristics: age, pregnancy order, pregnancy spacing, and pregnancy loss history. Despite incomplete coverage, the WFS data on pregnancy loss provide considerable, and largely unexploited, insight on the dynamics of the reproductive career.

[Changing pattern of National Family Planning and Fertility Survey in Korea].

The authors review the evolution since the 1960s of South Korea's family planning and fertility survey programs. "In the 1960s, research was interested in respondents' contraception knowledge and practice rate and in the relationships between contraceptive knowledge and the practice rate....[The] major research emphasis in the 1970s and 1980s was measuring fertility and finding obstacles or problems to family planning projects." Recommendations for future research are made. (SUMMARY IN ENG)

Statistical modeling of selected aspects of the childbearing process with application to World Fertility Survey countries.

"A mathematical model for estimation of certain aspects of the childbearing process, which requires only data on age-specific fertility rates, is developed. Synthetic maternal childbearing indices, namely, mean ages at first and last birth, length of reproductive life span, inter-birth spacing, and proportion of childless women, in addition to the well-known mean age at childbearing, for the WFS [World Fertility Surveys conducted in developing] countries are obtained using the proposed model. The indices are free from age truncation effects, and, under certain assumptions, provide information about a cohort's completed fertility before the women stop reproducing. The effects of women's residence and education on fertility are also examined." (SUMMARY IN FRE)
