The evolution of different life history strategies and thus different ageing patterns essentially depends on the nature of the underlying trade-offs between survival and reproduction. To fully comprehend ageing, we need to understand these trade-offs.

Increasing proportions of couples are making childbearing decisions in stepfamilies but there has been no general comparative picture across European countries on stepfamily formation. The present paper aims to fill this gap and provides a comparison of European countries using macro-level...

There is a growing body of literature that looks at the causes of below-replacement fertility in developed countries. While the variation in childbearing patterns across countries and between socio-economic groups within a country has been studied in detail, little is known about the differences...

Previous analyses of period fertility suggest that the trends of the Nordic countries are sufficiently similar to speak of a common "Nordic fertility regime". We investigate whether this assumption can be corroborated by comparing cohort fertility patterns in the Nordic countries. We study...

Extending recent research on parental gender preferences in the Nordic countries, this study uses unique register data from Finland and Sweden (1971-1999) that provide us with the opportunity to compare childbearing dynamics and possible underlying sex preferences among natives and national...

Hamilton quantified the force of selection on an age-specific mutation. Hamilton’s indicators of the age-specific force of selection always decline with age. This result is of profound importance to the theory of the evolution of senescence. Here I derive alternative indicators within...

The relationship between increasing women’s earnings and rising divorce rates frequently has been explained by the so-called independence effect: If a wife enjoys a higher earning than her husband does, she gains less from marriage. It has also been argued that in a society with egalitarian...

This paper analyzes the impact of women’s economic activity, earnings and take-up of child home care allowance on childbearing, using a ten percent sample from a longitudinal register data set that covers the entire female population of reproductive age in Finland in 1988–2000. Results show...

It has been argued recently that a society’s ‘gender system’ influences parents’ sex preferences for children. If this was true, one should expect to find no evidence of such preferences in countries with a high level of gender equality. In this paper we exploit population register data...
