"The present study is an attempt to identify some of [the]
extra-economic influences on demographic behaviour. It begins by
recognizing that region or culture is an important correlate of
demographic behaviour. Next, it tries to identify the attributes of a
region or culture which might be the actual determinant of such
behaviour and concludes that, in the Indian case at least, and possibly
in several other areas with cultural differences in demographic
indicators, the status of women is a prominent determining attribute.
The study then tries to make a more general argument in favour of a
significant connection between the status of women, as defined in
specific ways, and demographic behaviour, as measured by fertility,
child mortality, and gender differences in physical welfare. A
predominant feature is the attempt to identify the proximate
determinants in the observed connections between women's roles and
these measures of demographic behaviour."

The prospects for the French national retirement
pension scheme are reviewed in light of current demographic trends.
The authors note that the present scheme can only remain viable if the
population continues to grow. Since this scenario is unlikely, the
various alternatives that would keep the system financially solvent are
reviewed. The authors conclude that a postponement of the legal age
for retirement is preferable to a reduction in benefits or the
development of a pay-as-you-go system.

The authors examine
and compare changes in the populations of North and South Korea since
the post-World War II partition of the country, using data released in
1989 by the government of North Korea. "Korea's prolonged and
involuntary partition poses two basic questions. First, to what extent
have the social and economic characteristics of the separated
populations diverged during their decades under rival polities?
Second, if a collapse of Communist power were suddenly to occur in
Korea...what sorts of practical problems would the divergences
manifested during the separation pose to the reintegration of the
Korean nation?...[The] data permit reconstruction and projection of
some basic...social, demographic, and economic trends in North Korea
under Communist rule. They also provide a basis for some preliminary
comparisons of development in North and South Korea--and a starting
point for assessing some of the practical issues that might attend
their eventual reunification."

problems for statisticians. We describe some of these problems, how
they have been tackled so far and what remains to be done. The
discussion touches on topical statistical methods such as smoothing,

well as asking fundamental questions for frequentist statistics." The

models testing several measures of consumption consistently showed
moderate or regular drinkers to have lower risk of death than
teetotalers. Regular drinkers had lower overall and CHD mortality than
lifetime abstainers....These results lend support to the hypothesis of
the beneficial effect of moderate drinking, with respect to

of a variety of social roles among both men and women. The data are
from a large health maintenance organization (HMO) in Oregon. "The
findings show that for women, particular qualities of the marital and
work roles are predictive of subsequent morbidity and mortality. For
married women, equality in decision making and companionship in
marriage are protective against death. None of the marriage
characteristics are predictive of health outcomes among men. Work
support is protective against death, malignancy, and stroke among
employed women, and work stress increases the risk of ischemic heart
disease among employed men."

The
effect of family trauma experienced during childhood on the development
of health problems later in life is examined. The author finds that
"such traumas lead to an increase of between 16 and 48 per cent in the
average number of reported common illnesses, and to a general feeling
of malaise. In the case of 23 of the 28 illnesses listed in the
questionnaire, a statistically significant correlation was found
between repeated illness and family traumas experienced before the
eighteenth birthday. Women seem to be more sensitive to such
experiences than men." Data are from a survey of 4,650 French

"This article
describes the second stage of a research project on sexual networking
that aims to further understanding of the spread of sexually
transmitted diseases and HIV/AIDS in Ondo State, Nigeria. A sample of
488 males aged 15-50 were interviewed in depth to ascertain (1) the
numbers and characteristics of their sexual partners, (2) the numbers
and characteristics of the partners of those partners, and (3) the
extent to which these relationships were commercial. In addition, a
census was taken of all commercial sex establishments in order to
estimate the numbers of their clients. The results show that male (and
female) sexual networking is extensive, that in most nonmarital
relationships men do not have accurate knowledge of their partners'
partners, and that detailed questioning provides a reasonably accurate
picture of the number of these relationships that are commercial in
nature. The situation revealed was one of sexual diffusion rather than
one with a strong focus on commercial sex workers, which fits the model
of a slowly increasing HIV/AIDS epidemic rather than an explosive
one."

covered is from 1983 to 1989. "The Iraqi experience demonstrates how,
even in the midst of war, 80 percent of childhood diseases were
prevented and/or treated; how two-thirds of childbirths were safely
handled at the grassroots level by traditional birth attendants; and
how women community health motivators successfully raised mothers'
awareness of health problems and mobilized them to change their child
health care practices. These successful interventions saved the lives
of thousands of young children annually."

age in Sweden accounts for the decline in the twinning rate from the
19th century to the middle of the 20th century. The later decline in
twinning rate cannot be explained by changes in maternal age and
parity. Fecundity appears to be higher in mothers of twins than in
other mothers."

include the use of assisted pregnancy techniques, and the fact that

and who postponed their child bearing, have increased their
fertility."
