A Nation of Bastards? Registered Cohabitation, Childbearing, and First-Marriage Formation in Iceland, 1994-2013

Abstract

Nowhere in Europe is extramarital childbearing more pervasive than in Iceland. Roughly, 70% of children born in 2018 were conceived outside of marriage, thereof 83% of firstborn, which, on the surface, puts Iceland at the vanguard of a development often associated with a second demographic transition. In this study, we investigate the union formation behaviour of Icelandic women during a period of 20 years (1994–2013) with the objectives of gaining insight into the interplay of childbearing, registered cohabitation, and marriage and to enhance our understanding of the function of registered cohabitation in the family-building process. We use administrative population register data, covering the childbearing and marital history of the total female population born in Iceland during 1962–1997. The data are analysed by means of event history techniques and presented as annual indices of first-registered cohabitation and first-marriage formation, respectively. We find indications of forceful postponement of registering cohabitation over time, but a stable portion of around 80% of women registered cohabitation before any first marriage or age 46. Around 70% of women married before age 46, and the standardized marriage rates remained relatively stable during most of our study period. Our findings suggest that within a context such as the Icelandic one, most people tend to marry, regardless of the prevalence of cohabitation. We propose that registered cohabitation should be seen as providing a semi-regulated union status for prospective parents in relation to childbearing. Marriage on the other hand could be seen as providing an elevated union status to couples.
