Historical Germany represents a perfect laboratory for studying interregional demographic differences, yet the historical family structures in this part of the European continent remain largely unexplored. This study documents the variability of living arrangements using an aggregate measure of...

This article explores whether this is predominantly a temporary phenomenon related to the post-communist transition crisis, or whether longstanding...

type="main" <p>This article contributes to the geographic analysis of fertility decline in the demographic transition in Europe. We reanalyze Galloway, Hammel, and Lee's (1994) Prussian data with spatial analysis methods. Our multivariate analysis provides evidence of the predictive effect of both...</p>

In this paper we establish the asymptotic distribution of DeFries-Fulker (1985) regression estimates for heritability and shared environmental influences with double-entry twin data. A simple formula to estimate the covariance matrix of the coefficients in DF-regressions is provided, and...

Demographers have increasingly argued that social interaction is an important mechanism for understanding fertility behavior. Yet, substantial uncertainty exists whether ´social learning´ or ´social influence´ constitutes the dominant mechanism through which social networks affect...

Bongaarts and Feeney (1998) have recently proposed an adjusted total fertility rate to disentangle tempo effects from changes in the quantum of fertility. We propose an extension to the Bongaarts and Feeney formula that includes variance effects, i.e., changes in the variance of the fertility...
