Insecurities and risks related to ageing in a foreign country could fuel return migration among international retirement migrants. The few studies examining retirement migrants' return have been small in scale and focused mainly on return intentions rather than return behaviour. In this paper, we examine the prevalence and predictors of return migration among retirement migrants and the discrepancy between return intentions and return behaviour. We collected survey data on a representative sample of 5,065 Dutch retirement migrants in 40 destinations and combined them with administrative data on return migration. Three years after data collection, almost 9 per cent had returned to the Netherlands, whereas less than 5 per cent had intended to return during this period. Our findings show how age-related changes and transnational ties to the country of origin increase the likelihood of return. Our results also suggest that retirement migrants may underestimate the long-term implications and social embeddedness of the return migration decision.

In the UK, cohabitation has become the normative type of first co-residential partnership. While some couples go on to marry, others increasingly continue to cohabit or break up. One possible explanation is the rise in young people's economic precariousness. However, few studies have analysed this hypothesis empirically for the UK. By analysing data on cohabiting couple dyads from 1991 to 2019, we explore how economic precariousness (measured by four traits: employment, labour income, savings, and financial perceptions) relates to marriage and to cohabitation dissolution. The types of precarious traits seen in couples, alongside their distribution between partners, are crucial for understanding socio-economic differences in cohabitation outcomes. Marriage is less likely among couples where the man is jobless or has no savings, suggesting that marriage is a financially committed relationship, more reliant on men's resources. Couples where women hold worse financial perceptions than men are most likely to separate, highlighting the importance of subjective measures.

In countries without adequate death registration systems, adult mortality is often estimated using orphanhood-based methods. The HIV pandemic breaches several assumptions of these methods, for example, by increasing the correlation between maternal and child survival. Using microsimulations we generated 1,152 populations facing HIV epidemics and evaluated different orphanhood-based estimates against the underlying mortality rates. We regressed survivorship probabilities on proportions of respondents with surviving mothers, adjusting for trends in seroprevalence and coverage of antiretroviral therapy, to obtain new coefficients. We tested the different methods on survey and census data from 16 African countries with high HIV prevalence. We found that the original orphanhood method underestimates mortality during an AIDS epidemic, but better estimates can be obtained using new coefficients applied to synthetic measures of maternal survival. The resulting estimates agree well with those of the United Nations Population Division. Orphanhood-based estimates can fill data gaps in adult mortality, including in countries with high HIV prevalence.

This paper presents approximate estimates of the size, growth, and changing demographic characteristics of Australia's lesbian, gay, and bisexual (LGB+) population. We used weighted data from a longitudinal panel survey at three time points to estimate the population by sex and age group in 2012, 2016, and 2020, and we applied cohort analysis to help understand the drivers of its growth. The LGB+ population aged 15 and above doubled in size over the eight-year period, increasing from 0.58 million in 2012 to 1.18 million in 2020. More men than women identified as LGB+ in 2012, but this had reversed by 2016. Our estimates show that the LGB+ population is young and becoming younger over time, with cohort analysis showing that its growth has been driven primarily by recent cohorts of young women with a bisexual identity. We discuss what might be driving this growth and whether our results suggest continued rapid LGB+ population growth in future.

Young adults moving between wealthy countries for work and adventure are an under-studied group of international migrants. We use a unique combination of full population register data from Sweden and Norway to explore the so-called 'Party Swedes': young Swedes who emigrated to Norway in 2010-12. We follow them and track their median incomes before they left Sweden, during their stay in Norway, and after their return to Sweden. Moreover, we model selection into migration and return, as well as individual income levels after return. Our results suggest that in economic terms, the 'party penalty' clearly seems larger than the 'party premium'. Even though the young Swedes earned well in Norway, this did not translate into higher incomes after returning to Sweden than among their non-migrating peers. These results add to the literature on migrants' income premiums after return, focusing on liquid youth migration.

This study investigates partnership changes and childbearing among immigrants and their descendants in the UK, France, and Germany. Our analysis of longitudinal data shows, first, significant diversity in family trajectories among immigrants and their descendants in Europe. Immigrants from other European countries and their descendants tend to cohabit prior to marriage, and their fertility in unions is often similar to that of the native population. In contrast, South Asians and Turkish populations exhibit marriage-centred family behaviour with elevated third-birth rates. Individuals of sub-Saharan African or Caribbean origin display higher rates of non-marital family transitions. Second, we observe some changes in partnership and childbearing patterns across migrant generations; these are stronger for fertility than for partnership patterns. Third, migration background is particularly associated with partnership patterns, whereas the destination country context influences childbearing patterns. We expect some patterns to persist across future migrant generations (e.g. preference for marriage vs cohabitation), whereas others are likely to vanish (e.g. large families).

Using census and survey microdata from 49 African countries across 415 subnational areas, we offer a comprehensive overview of household size and composition in Africa. The study emphasizes the potential of these data for understanding family dynamics through co-residential units. Clear regional patterns emerge, showcasing a wide range of household sizes across the continent. We find that household size is linked primarily to the number of children and secondarily to the presence of other family and non-family members beyond the nuclear household. The analysis of household composition also highlights the uneven influence of polygyny and extended families. This research is a first step in examining harmonized census and survey data to delve into the structure and dynamics of households across Africa from a demographic perspective.

In this paper, we combine administrative data for Spain from 2010 to 2018 with meteorological data, to identify the effect of daily mean temperature on fertility. We demonstrate for Spain that hot days (≥25°C) decrease the total fertility rate nine months after exposure. Moreover, we do not observe any substantial heterogeneities in the effect of heat by mother's age, mother's educational attainment, sex of the newborn, climatic area, or air conditioning penetration. Our results suggest that climate change may be altering the seasonal distribution of births and affect fertility rates in a context with low fertility and rapid population ageing.

Technological change and globalization have caused unprecedented transformations of labour markets, resulting in a growing division between workers who perform cognitive vs non-cognitive tasks. To date, only few studies have addressed the fertility effects of these long-term structural changes. This study fills that gap. We measure the cognitive task content of occupations using data from the Employment Survey of the German Federal Institute for Vocational Education and Training, which we link to individual histories from the German Socio-Economic Panel 1984-2018. We find that women and men with non-cognitive jobs are increasingly less likely to enter parenthood; this is reflected in lower first-birth intensities but also in higher probabilities of childlessness compared with workers in highly cognitive jobs. These findings imply that structural shifts in the labour market are exacerbating disparities between low-skilled and highly skilled individuals, not only within the labour market but also in the realm of family formation.

Strictly Orthodox Jews, otherwise known as Haredi, constitute about one-quarter of the total Jewish population of the UK. This population is growing very quickly. A religion question, first introduced into the census of England and Wales in 2001, is generally used to estimate the Haredi Jewish population. This paper claims that Haredi Jews have been severely and consistently undercounted in the census, leading to detrimental consequences for a proper understanding of the numerical dynamics of the UK's Jewish population as a whole and also compromised service provision. This paper develops an alternative estimation system that uses different types of administrative sources to quantify and correct for the census undercount of Haredi Jews. The paper proceeds to show that the undercount is not an exclusively 'Haredi problem': other ethnic and religious groups are also likely to be affected by it.
