Patterns of diversity in age at death are examined using e†, a dispersion measure that also equals the average expected lifetime lost at death. We apply two methods for decomposing differences in e†. The first method estimates the contributions of average levels of mortality and mortality...

Maternity leave policies are designed to ease the tension between women’s employment and fertility, but whether they actually play such a role remains unclear. We analyze the individual-level effects of maternity leave on employment outcomes and on second conception rates among Russian...

This paper is concerned with sensitivity analysis of life disparity with respect to changes in mortality rates. Recently Zhang and Vaupel introduced a ”threshold age”, such that averting deaths before that age reduces disparity, while averting deaths after that age increases disparity. We...

The conception of the cost of reproduction provides an important insight on connection between fertility and life span in living organisms. Despite substantial progress in understanding this connection many important features of fertility-longevity trade-off are masked by confounding factors,...

The main purpose of this paper is to report on an initial validation of methods for dealing with micro-census data with no delineated households. After describing the 1819 census of Rostock we test the possibilities of using an algorithm that creates households according to a strictly defined...

The view of Eastern Europe as a locus of complex family organisation and familistic societal values has reached the status of general dogma in Western social sciences and demography. By offering an overview of almost entirely unknown scholarly achievements of Eastern Europeanists, this essay...

In the twenty years since the reunification of Germany, we have seen a convergence of total fertility rates in the eastern and western parts of the country, but differences remain in the timing, number and spacing of births. Our aim in this paper is to better understand the persistence of these...

The tendency of women to outlive their own fertility has been explained allometrically, with age at reproductive cessation attributed to ovarian follicle depletion in allometrically appropriate ovaries, and longevity related to brain and body scaling. However, because women's age at reproductive...

Females in all mammalian species care for their offspring, while most mammalian males do not. This failure of paternal investment is generally explained in terms of a trade-off between paternal care and mating competition. While there has been great interest in the optimal pattern of investment...
