While the fertility levels of immigrants to Europe have been examined in the recent literature, the childbearing patterns among their descendants have received little attention. Using longitudinal data from eight European countries and applying Poisson regression models, the study shows that many descendants of immigrants exhibit first-birth levels that are similar to the 'native' population in their respective countries; however, first-birth levels are elevated among women of Pakistani and Bangladeshi origin in the UK and for those of Turkish descent in France and Belgium.

Some argue that this is a consequence of selection effects and that once these are controlled for premarital cohabitation has no effect on dissolution. We extend this research by examining whether the effects of premarital cohabitation on marital dissolution vary across settlements within a country. Using retrospective event-history data from Austria, we model equations for union formation and dissolution jointly to control for unobserved selectivity of cohabiters or noncohabiters. Our results show that those who cohabit prior to marriage have a higher risk of marital dissolution. However, once selection effects are controlled for, the risks of marital dissolution for those who cohabit prior to marriage are significantly lower than for those who marry directly. We show that strong selection effects relate to both cohabitation and direct marriage and these effects are consistent across all settlements.

While there is a growing literature on the health and mortality of international migrants, few studies have investigated the health of people moving within a country. We use individual-level data from the UK 1991 population census and apply the technique of logistic regression to analyse health differences between migrants and non-migrants. The analysis of the prevalence of a limiting long-term illness shows that on average migrants have better health than non-migrants. Scottish migrants are origin country selective by health, whereas English migrants are host country selective by health. English men in older working ages show significant health advantages over both origin and host populations. No evidence was found to support a Salmon Bias.

While there is a large, multi-disciplinary literature looking at the determinants of union dissolution in Europe and North America, the possible impact of geographical mobility has received little attention. This is despite the fact that moving is a stressful life event and

This advantage is often attributed to health selection processes in migration and to protective health behaviours. Little research has examined the role of data quality, especially the registration of moves. Registration errors relating to moves between origin and host countries can mismatch deaths and risk populations, leading to denominator bias and an under-estimation of migrant mortality (data artefact). The paper investigates the mortality of immigrants in England and Wales from 1971 to 2001 using the Office for National Statistics Longitudinal Study (ONS LS), a 1% sample of the population of England and Wales. We apply parametric survival models to study the mortality of 450,000 individuals. We conduct sensitivity analysis to assess the impact of entry and exit uncertainty on immigrant mortality rates. The analysis shows that most international migrants have lower mortality than natives in England and Wales. Differences largely persist when we adjust models to entry and exit uncertainty and they become pronounced once we control for individual socioeconomic characteristics. This study supports low mortality among immigrants and shows that results are not a data artefact.
