These are the proceedings of a conference held in Chicago,
Illinois, in July 1988 concerning the responsible use of hospital
mortality data in the United States. The purpose of the conference was
to share among the groups participating what has been learned
concerning the past public release of hospital-specific mortality
statistics, and to make recommendations concerning the future release
of such data in order to improve the quality of health
care.

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."

such a question. Next, the article outlines the history of the

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.

often leads to a compromise between attaining the overall objectives of

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

survey showed a preference for the two-child family in urban areas,
greater preference for sons in rural areas, and an ideal age at

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

principle, the registration of all births occurring in the maternity
