Variance in age at death equals average squared remaining life expectancy at death
life disparity life table entropy remaining life expectancy variance in age at death
2014/11/26
Background: Variance in lifespan $\sigma^2$ and life expectancy lost due to death $e^{\dagger}$ are important demographic indicators of life disparity.Objective: I show that variance in age at death e...
How does education change the relationship between fertility and age-dependency under environmental constraints? A long-term simulation exercise
aging dependency human capital low fertility optimal fertility
2014/11/26
Background: When asked what a desirable fertility level for populations might be, most politicians, journalists, and even social scientists would say it is around two children per woman, a level that ...
Another 'futile quest'? A simulation study of Yang and Land's Hierarchical Age-Period-Cohort model
age period cohort models identification problem MCMC simulation Yang and Land
2014/11/26
Background: Whilst some argue that a solution to the age-period-cohort (APC) 'identification problem' is impossible, numerous methodological solutions have been proposed, including Yang and Land's Hie...
Heterogeneity's ruses: How hidden variation affects population trajectories of age-dependent fecundity in Drosophila melanogaster
Drosophila fecundity heterogeneity plateau reproductive life span senescence simulation
2014/11/26
Background: Progress in understanding senescence requires information about age-dependent changes in individual organisms. However, for experimental systems such as Drosophila melanogaster we usually ...
Lifetime income and old age mortality risk in Italy over two decades
free knots spline health inequalities Italy lifetime income mortality old age regional differences socioeconomic status

Age groups and the measure of population aging
age distribution aging indexes demographic measures old age optimal grouping population aging
2014/11/25
Background: Measures of population aging are important because they shape our perception of demographic trends. Indicators of aging based on fixed ages contributed to a dramatic portrayal of demograph...
An examination of black/white differences in the rate of age-related mortality increase
aging cross-over mortality senescence USA
2014/11/25
Background: The rate of mortality increase with age among adults is typically used as a measure of the rate of functional decline associated with aging or senescence. While black and white populations...

Background: A well-documented association exists between age at marriage and the risk of divorce. However, substantial gaps in our knowledge and understanding of ist origins, nature, and implications ...
Distortion of regional old-age mortality due to late-life migration in the Netherlands?
migration mortality old age regional differences
2014/11/25
Background: Regional mortality differences are an important public health indicator and can serve as the basis for population forecasts and local planning. Health-related migration at old age may dist...
