It is difficult to measure incidence and prevalence rates for rare conditions.For very rare conditions, the sample size requirements begin to approach the total population size. However, there is a ...
Organized and funded by the IUSSP Scientific Committee on Historical Demography in collaboration with the Inter-university Consortium for Political and Social Research, University of Michigan, USA, an...
Background: The gamma-Gompertz model is a fixed frailty model in which baseline mortality increases exponentially with age, frailty has a proportional effect on mortality, and frailty at birth follows...
To develop a matrix model to compute all the statistical properties of longevity from the gamma-Gompertz and related models.
Spatio-demographic data sets are increasingly available worldwide, permitting ever more realistic modeling and analysis of social processes ranging from mobility to disease transmission. The informati...
Background: The present research evaluates the possibility of spatial heterogeneity in the effects on neighborhood crime rates of both traditional demographic indicators - immigrant concentration, rac...
In this article we propose to study occupational careers with historical data by using multilevel growth models. Historical career data are often characterized by a lack of information on the timing o...
Humans, and many other species, suffer senescence: mortality increases and fertility declines with adult age. Some species, however, enjoy sustenance: mortality and fertility remain constant. Here we ...
This study has two objectives: (1) to test a new version of the logistic model for the pattern of change over time in age-specific adult mortality rates, and (2) to develop a new method for projecting...
Probability Models of Migration: Complete and Incomplete Data .
Sri Lanka's multi-ethnic society provides a useful example of how fertility behaviour can be affected by ethnic differences. This article elaborates on the possible sources, extent and nature of the v...
The workshop brought together specialists in the theory and in different areas of application of age- and/or duration-structured dynamical systems. Among those areas are demography, population dyna...
Perturbation analysis examines the response of a model to changes in its parameters. It is commonly applied to population growth rates calculated from linear models, but there has been no general appr...
There is much interest these days in the importance of community institutions and resources for individual mortality and fertility. DHS data may seem to be a valuable source for such multilevel analys...
It has long been recognized that the patterns of growth play an important role in the evolution of age trajectories of fertility and mortality (Williams, 1957). Life history studies would benefit from...
