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...

Some 20 years after unification, the contrast between East and West Germany provides a unique natural experiment for studying the persistence of communist-era family patterns, the effects of economic change, and the complexities of the process of fertility postponement. After unification,...

At the 70th 'anniversary' of Münzer’s death, ancient history ‘celebrates’ a more than twice long history of debate on population matters in the Roman Republic and early Empire. More than 170 years of discussion have hitherto not led to any conclusive answer on the basic question against...

This paper studies the short-term fertility intentions of women and men and their subsequent behavior. On the one hand, the predictive strength of fertility intentions is of interest. On the other hand, the most important determinants that inhibit or enable the realization of fertility...

The demographic transition is a universal phenomenon. All regions of the world experience a change from high levels of mortality and fertility to low levels. The onset and pace of the demographic transition vary between regions and countries because of differences in timing of events and...
