"This paper evaluates the reliability of morbidity and mortality data for one disease--measles--collected by lay interviewers in a rural area of Senegal. The data are evaluated primarily using consistency checking, relying on what is known about the nature and epidemiology of measles. Based on the findings of this research, we offer suggestions for improving the lay reporting of health-related data."

In Eng.
The author assesses the system of lay reporting that has been used by the Matlab Demographic Surveillance System in Bangladesh since 1975. "Section 1 of this chapter describes this simple system, reviews some insights about recent changes in child mortality which have been obtained using it, and discusses its major weaknesses--biases arising from interviewer and classifier inconsistency and confusion of locally defined illness with medically defined disease, and lack of provision for multi-causality. Section 2 presents an experiment with a more structured lay-reporting approach, which was developed to overcome some of the weaknesses of the simple system....The results obtained for neonatal deaths, an age group for which the results obtained from the simple system are not very enlightening, indicate the usefulness of this new approach."

"During the past two decades, the Government of Morocco has pursued a vigorous policy aimed at bringing the Kingdom's civil registration and vital statistics (CR/VS) systems to a state of adequacy so that these systems can make appropriate contributions to the nation's social and economic development. In addition to a variety of measures aimed at improvement, the Government has carefully studied the operation of the CR/VS systems to uncover problems which need to be resolved. In the last few years, the United Nations Population Fund has supported projects to assist Morocco in this area. This paper discusses the deficiencies in the systems and the measures taken to accelerate the improvement of CR/VS in Morocco."

"This paper reports on the results of a split-ballot experiment conducted in 1987 to test alternative versions of the [U.S.] decennial census long form. Two forms were randomly assigned and self-administered in group sessions involving a total of 515 respondents. The order of race and Hispanic origin items was experimentally manipulated. The standard long form asks race, then Hispanic origin. The experimental form reversed the order of the items in order to reduce perceived redundancy, and to create a more restricted frame of reference for the race item."

Arguments both for and against the inclusion of an ethnicity question in the 1991 British census are presented. "The article focuses especially on the uses of such data in a local context, with particular reference to local-authority uses. It strongly favours an ethnicity question and considers the arguments against to be either unfounded or outweighed by the substantial benefits to be gained from such a question. Next, the article outlines the history of the development of the 1991 Census question and considers the results of the 1989 Census Test. It then goes on to consider what changes have occurred since 1979 to make an ethnicity question a practical possibility now compared with a decade ago. In conclusion, some issues for the future are identified."

The authors review some recent demographic surveys undertaken in Nigeria and evaluate the adequacy of their data concerning women. They first illustrate the inadequacy of some earlier data sources. The authors then look at three recent demographic surveys as possible sources for such data, including the Family, Fertility, and Family Planning Survey of 1971-1973, the Lagos Parity Study of 1976, and the Nigeria Fertility Survey of 1981-1982. Topics considered include maternal roles, conjugal roles, and women's employment. They conclude that the surveys provide detailed information on particular aspects of female roles as well as critical baseline data for the study of change.

"This report presents the initial results of the Kenya Community Survey in numerous descriptive tables. The objectives of the survey were to test several hypotheses about the relationship of demographic phenomena to community characteristics and to develop community survey methodology. The experience of the KCS shows that it is feasible to conduct a stand-alone community survey designed to be linked with a large-scale fertility survey." After an initial focus on questionnaire design and interviewing methods, chapters concern rural isolation, including access to family planning services; marriage and bride wealth; women's groups; and land tenure.

"The annual administrative survey of student registrations in [French] universities has been used to study the reliability of the standard classification by socio-occupational groups used. A cross-tabulation of groups for the occupations of heads of household of students first enrolled in 1975, and re-registered in 1976...showed changes of which only a small fraction could be ascribed to occupational mobility....These changes, which affect different groups in different ways are not random. An analysis of the size of these changes in different groups and of the relationship between groups, demonstrates the major mechanisms that underlie these changes, and the meaning that those involved in the classification attach to different groups."

"In this paper several examples of [French] surveys in which different sampling fractions were used for different sections of the populations are presented....Attempts to optimize the sample design may result in samples which are too specialized to meet the objectives of a demographic survey....Moreover, the use of different sampling fractions often leads to a compromise between attaining the overall objectives of a survey and estimates for different sub-groups of the population, rather than in a true optimization. This is also true of the use of panels for the determination of sampling errors, in surveys which are designed to measure change and deal with a situation at one point in time. Geographical overrepresentation...does not raise any specific problems....The problems raised are similar to those encountered in the study of very small populations."

The results of a fertility and mortality survey carried out in Maharashtra state, India, in 1980 are presented. This survey, which was one of a planned series of state-level surveys, covered a state-representative sample of some 7,500 families. The first chapter presents a summary of the main findings, methodological issues, and policy implications. Chapters are included on survey design, population characteristics, fertility and mortality rates and differentials, family formation and cumulative fertility, knowledge and use of family planning, indirect estimates of fertility and mortality, and data quality and response errors. The survey showed a preference for the two-child family in urban areas, greater preference for sons in rural areas, and an ideal age at marriage higher than actual age at marriage.

"This article tries to describe the prevailing public opinion about questions of demographic development in the Federal Republic of Germany in...light of the results of two representative demographic opinion polls carried out by the Federal Institute for Population Research in 1984 and 1989....The results give evidence of a relatively constant public opinion with regard to the general judgment of demographic development and the assessment of the reasons of the birth decline and its consequences for the social development. Changes are more evident, however, in the assessment of the immigration and integration of foreigners. Evaluation of some questions newly included in the 1989 poll shows that the German population clearly differentiates when assessing the consequences of the immigration of foreigners, Germans from the GDR and ethnic Germans from Eastern European countries."

"I will limit the discussion in this chapter to the principle of the multi-round survey, and its particular application in the IFORD surveys. I shall organize the comments in two parts: the weaknesses and strengths inherent in the study of a cohort of births, and those inherent in the particular IFORD application (i.e. the urban, hospital-based panel study). The chapter ends with a discussion of a few design changes that might be considered in future multi-round surveys." The article is based in large part on the author's experience with the survey of Bobo-Dioulasso, Burkina Faso. "The design of the surveys involved, in principle, the registration of all births occurring in the maternity hospitals of a city during a period of 12 months, and the interviewing of the mothers at the time of delivery; in several instances, a representative sample of these births was deemed sufficient to provide a significant number of cases."
