Mean ages at parities: an indirect estimation.

"The objective of this paper is to describe an indirect approach for estimating the age patterns of occurrence of birth by parity. The main concern here is not of estimating the frequency of occurrence of births (in a period of time) in relation to the population (birth rate) or in relation to the number of females (fertility). Rather, the focus here is on the ages of first, second, and subsequent births, and on their shifts over time. Essentially, the approach is an extension of Hajnal's method for using proportions single to estimate singulate mean age at marriage...." The approach is illustrated using data from the 1975 Pakistan Fertility Survey and the 1990-1991 Pakistan Demographic and Health Survey. A comment by Sultan S. Hashmi is included (pp. 560-1).

[Estimation of infant and child mortality in the eastern provinces of Cuba].

An estimate of infant and child mortality in the eastern provinces of Cuba is presented using the Brass method as adapted by Trussell. "Estimations by urban and rural zones are also performed within the provinces studied, and results are compared with those possible to obtain by continuous statistics. Results obtained show that in the eastern [part] of the country Holguin and Guantanamo are the provinces with highest infantile mortality rates, and the lowest rates correspond to Granma, followed by Santiago de Cuba."

Past and recent attempts to model mortality at all ages.

"Most laws of mortality are partial in the sense that they apply only to a broad age group and not to all ages. This paper focuses on three laws of mortality that apply to all ages. Two of them were developed by the actuaries Thiele and Wittstein in the late 19th century. The third, developed by Heligman and Pollard, is of recent origin. The three laws are discussed with references to Scandinavian mortality data. The results suggest that the most recently proposed law can be used for generation of model life tables, for making population projections, simulations, and other statistical work where there is a need for a realistic model of human mortality."

Accuracy of indirect estimates of maternal mortality: a simulation model.

A simulation model was developed to test the accuracy of indirect estimates of maternal mortality (the sisterhood method). The model generated a first generation of grandmothers, a second generation of mothers (with brothers and sisters), and a third generation of children (births). In the second generation, maternal mortality was introduced. Empirical values for the parameters of fertility and mortality were taken from a prospective survey in Senegal (Niakhar). Results based on 100 simulations of the same situation revealed several limitations of the sisterhood method: The indirect estimates could fall as far as 33 percent from the true values on individual cases; the indirect estimates tended to be systematically higher than the direct estimates; their range was wider, as were their confidence intervals; and biases were particularly strong for the younger age groups of respondents. Reasons for these biases are explored.

[Family reunification and family-formation migration, 1987-1991].

"Indirect estimates were made of family reunification and family formation migration [in the Netherlands], based on such demographic characteristics as nationality, country of birth, age, marital status, year of marriage and family situation after the migration. The estimates are based on the 1992 enumeration from the municipal population registers." (SUMMARY IN ENG)

Estimating mortality in Benin from a multi-round survey (1981-83).

"We shall in the present study proceed as follows: first, present the methodology used for the Benin Multi-Round Survey (BMRS); second, analyse the quality of the data, by evaluating the impact of mobility on the results, by a critical assessment of the levels obtained for several mortality indicators and by using indirect methods to estimate the coverage of deaths occurring between rounds; third, construct the first life tables for Benin based on raw data. We shall then consider in what these life tables are specific, and where they diverge from the standard life tables."

Recent estimates of adult mortality from widowhood in Bangladesh: a critical comparison.

"The indirect techniques of demographic estimation available at the moment are often inadequate to estimate levels in the presence of trends. The generalised stable population relations have been applied to census and survey data collected in Bangladesh for the estimation of adult mortality. This method combines two sets of widowhood data and yields estimates for the intersurvey period. The generalised stable population relations are based on the assumption that the population is closed to migration between the censuses. The application of the method is simple whatever may be the length of the inter survey period. But the method may be found to be affected by age misreporting and other errors."
