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."

Indirect estimation of infant mortality trends: simulation tests on the Feeney method.

The methods developed by Griffith Feeney for the indirect estimation of infant mortality are reviewed and tested using simulated data. It is concluded that the proposed method provides excellent results if all the specified conditions are satisfied. "The 'short-cut' method usually applied is appropriate only when the age-pattern of mortality is of (or close to) the Brass type. The more general method involving the solution of a complex equation will otherwise have to be used." By "simulating ideal situations where the method should otherwise work, the article shows the type and level of error that results when the age-pattern of mortality does not correspond to that of the model. The non-respect of other assumptions means a risk of further error but the crucial assumption is that which concerns mortality." (summary in FRE, ITA)

Measurement of adult mortality in less developed countries: a comparative review.

"This paper compares the direct and indirect methods used to measure adult mortality in the developing world. No other approach can substitute fully for accurate and complete vital registration, but in many countries it is unrealistic to expect the registration system to cover the majority of the population in the foreseeable future.... The difficulties involved in measuring adult mortality using surveys and other ad hoc inquiries are discussed.... While the choice of methods must depend on each country's situation, direct questions require very large samples and are unreliable in single-round inquiries. On the other hand, although indirect methods provide less detailed and up-to-date information than is ideal, they are adequate for many practical purposes. In particular, the experience of the 1980s suggests that questions about orphanhood perform better than earlier assessments indicated, and recent methodological developments have circumvented some of the limitations of the indirect approach."

[[Mortality estimation using proportional mortality indicators for developing countries]].

The author extends a technique for the indirect estimation of mortality originally developed by Courbage and Fargues. The technique is applied to national data from 35 developing countries for the year 1975. "Nine families of model life tables constructed by Coale and Demeny and the United Nations were applied to each of the object populations, and the level of mortality corresponding to the value of PMI (proportional mortality indicator: percentage of deaths at the ages 50 years and over) obtained from death registration data, was determined for each family." The author notes that the technique does not require assumptions regarding features of the population in question and is applicable to a non-stable population or an open population without any adjustment.

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."

Direct and indirect estimates of maternal mortality in rural Burkina Faso.

A retrospective study of maternal mortality was conducted in Nouna, a rural area of Burkina Faso in 1992. Strong evidence was found of a major mortality decline among children and young adults over the 50 years preceding the study: The estimated life expectancy of 36 years in around 1945 rose to 58 years in 1991. Direct and indirect (using the sisterhood method) estimates of the maternal mortality ratio (MMR) were compared. Overall, the direct estimate of the MMR (389 deaths per 100,000 live births) for women aged 15 and older was slightly lower than the indirect estimate (428 deaths per 100,000). Taking into account the biases involved in the use of information obtained from sisters, the direct estimates indicated a marked decline in maternal mortality over time from 569 deaths per 100,000 around 1941 to 305 deaths around 1987. The validity of both data and approach, as well as the discrepancies between the direct and indirect methods, are discussed.

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.

Estimating maternal mortality in Djibouti: an application of the sisterhood method.

In many developing countries even crude estimates of the level of maternal mortality are lacking and the prospects of fulfilling this need using conventional sources of vital registration and health service statistics are not encouraging. The constraint this imposes on the effective planning, management and evaluation of the programmes now being launched to reduce these neglected deaths is self-evident. It is less obvious how the majority of developing countries can be expected to meet the call for reliable estimates of maternal mortality by 1995. The sisterhood method provides a means of obtaining population-based estimates using household surveys for data collection. This paper describes the application of the method in Djibouti in the context of a rapid multi-purpose household survey in difficult field circumstances. In recent years the reduction of the level of maternal mortality in developing countries has become a priority for both national governments and international agencies. Attention has been drawn to the wide range of levels within and between countries and to the huge discrepancies in the lifetime risk of maternal death for women in the developed compared with the developing world. This risk has been estimated to range from 1 in 19 in West Africa to almost 1 in 10,000 in Northern Europe.

Mortality differentials in France during the late 18th and early 19th centuries.

"The very high quality of a set of marriage records for Paris during the 1860s made it possible to apply indirect methods to estimate adult mortality differentials by certain geographical and social criteria of the 19th century. The largest differences between groups were observed to be social, geographical origin apparently having little impact.... It is interesting that social differences in adult mortality are similar in magnitude to those observed today. Perhaps the principal factor of differentiation is then the level of child mortality.... It is by no means necessary to have a set of data as complete as ours. The indirect methods we have used proved largely adequate for estimating mortality differentials."

Estimates of the British Jewish population 1984-88.

"During the 20th century, estimates of the British Jewish population have been obtained by applying appropriate death-rates to communal mortality data. This death-rate method has become increasingly sophisticated with respect to the death-rates used. The exercise reported here covers more than 22,000 deaths recorded in the community over the 5-year period [1984-88].... An estimate of 308,000 is suggested for the community, in which deaths-related data are augmented by information about births within the community."
