The
author compares methods of analysis using data from a panel study of
the Federal Republic of Germany's Institute for Population Research.
"This does not only involve a comparison of the methods as such, but
above all also a comparison of the results (of these methods), of their
presentation and of the possibilities of interpreting them. The three
programmes selected for this paper represent methods for...so-called
multivariate analysis, in particular for the analysis of non-metric
data as they are included in the panel study...." Data are for a
sample of 1,868 women interviewed at least twice and concern women's
educational status and the qualities of
motherhood.

"In this paper, we investigate an extension
of the multistate stable population model, which makes allowances for
migration. The model is formulated as an inhomogeneous system of first
order partial differential equations with integral boundary conditions.
First, we construct its classical solution. Next, we reformulate the
system as an abstract inhomogeneous Cauchy problem on a Banach space,
and give its mild solution by using the population semigroup. Our main
purpose is to investigate the asymptotic behavior of the mild
solution."

analysis of mortality studies. Journal of Occupational Medicine,
Vol. 30, No. 1, 1988. 60-2 pp. Baltimore, Maryland. In Eng.
"In the
analysis of retrospective cohort mortality studies, persons lost to
follow-up are either withdrawn at the time of loss or are assumed to be
alive at the end of the study. It has been advocated that the former
method does not give a biased estimate of expected mortality in this
group, and is therefore the preferred method. In this paper, it is
argued that this approach is not always the best one, and that in
certain situations, depending on the method of follow-up used, assuming
that persons lost to follow-up are alive may give more accurate results
than withdrawing them at the time of loss." The data are from a recent
study concerning 28,901 workers in a meat cutters' union in Baltimore,
Maryland.

"Gingival emergence data for permanent teeth, obtained from an

years in Chandigarh, India, have been used to calculate the median age
and the 10th-90th percentile range of age, for a given number of teeth
present. From about 5 years (when the first tooth, on average,
emerges) up to the time of emergence of second molars (around 14
years), the total number of permanent teeth emerged can be used to
estimate the age of a child, with an error of about 13-34% of the
median age for males and about 11-35% for
females."

"It is known that there are pitfalls in the way of attempts to
construct an economic theory of population and growth based on formal
models of the family of the type developed by Becker. It is shown that
these pitfalls can be avoided by going slightly outside Becker's model,
modifying the typical family's budget constraint to allow explicitly
for the cost of raising children."

simple model of Malthusian population growth combined with
population-induced technological progress generates accelerating
growth. The model may be relevant for a first stage of growth in which
natural resource limitations can be overcome through technological
progress; it is not applicable to a later stage in which resource
constraints are more resistant. Parameter values are roughly inferred
from historical experience."

Two alternative ways of
distinguishing between the vital rates of two distinct populations are
introduced. In the first method, called direct standardization, the
effect of other factors is held constant when the effect of one factor
is estimated. The second method, indirect standardization, involves
choosing an approximate standard to estimate a specific rate. A method
of rate decomposition is also presented.

"A weighted
regression has been fitted to estimate the parameters of a model
involving functions of survivorship probability and age. Earlier, the
parameters were estimated by the method of ordinary least squares and
the results were very encouraging. However, a multiple regression
equation passing through the origin has been found appropriate for the
present model from statistical consideration. Fortunately, this
method, while methodologically more sophisticated, has a slight edge
over the former as evidenced by the respective measures of
reproducibility in the model and actual life tables selected for this
study."

The author seeks "to present a generalized illustration of changes
in the net maternity rates that can be incorporated in the so-called
integral equation of Lotka's stable population model and can still be
solved in the traditional way....As a result, the birth trajectory does
not necessarily attain a stable state. For certain patterns of
mathematical functions the trajectory eventually becomes stable while
for certain others it shows cyclical fluctuations....This information
is needed for deriving the long term solutions in addition to the
information about the intrinsic rate of growth which is obtained from
the traditional integral equation."

demographic behaviours in terms of hazard rates or transitional
intensities, this review paper shows that a framework of piecewise

both sexes, the multiregional stable population model is extended for
two-sex population."

This manual, intended for students and
researchers, is concerned with the methods used to study population
structure and change. The first part of the book "covers the topics
conventionally found in introductory textbooks of demographic
methods....These topics are the basic measures used in the analysis of
fertility, mortality, nuptiality and migration." The second part deals
with demographic models. "The models described are those which are in
common use for demographic estimation, and thus tend to describe the
patterns of mortality and fertility in terms of age. Models used for
more theoretical or explanatory purposes..., or the wide range of
models of human fecundability, are not covered. Nor is there any
mention of models of the migration process."

The
efficiency of Coulson's index and the median age in measuring the
intensity of demographic aging are examined using data concerning the
Canadian province of Quebec. The results suggest that Coulson's index
measures demographic aging much more precisely and corresponds
accurately to a regional model of aging dominated by the influence of
growth and the urbanization level of the municipalities
concerned.
