The practice of women eating after men is a common gender-inequitable food allocation mechanism among adults in Indian households and has been associated with poor health and nutritional outcomes for women. However, empirical evidence on whether a similar practice of girls eating after boys is prevalent among children is scarce. Using primary data from a household survey conducted in educationally backward areas of four Indian states, we provide new evidence of this practice among children. Almost 28 per cent of the sample households follow the mealtime custom of girls eating after boys. Scheduled Tribes and households with higher incomes are less likely to follow this practice. Other relevant factors include children's relative ages by sex and an interplay between family size and children's sex composition. While our findings may not be generalizable, they suggest an intersectionality between gender and other dimensions of inequality, namely social identity and economic class.

We know little about the effects of the reproductive health burden in contexts where unsafe abortions, miscarriages, stillbirths, and low-quality maternal care are common. The aim of this study is to investigate the use of allostatic load to understand the impact of reproductive histories on later-life health. We applied path models to the Indonesian Family Life Survey with a sample of 2,001 women aged 40+. Although number of children was not associated with allostatic load, pregnancies not ending in live birth and parenthood before age 18 were both negatively associated with health. We also identified clear cohort and educational effects and a possible rural advantage. Our contribution is twofold: we highlight the importance of reproductive histories beyond live births on women's later-life health in a context of increasing population ageing, and we demonstrate the applicability of using allostatic load to measure health outside the Global North.

While extensive literature documents the massive fertility delay of recent decades, knowledge about whether and how attitudes towards the timing of births have changed in Europe remains limited. Using data from two rounds of the European Social Survey, we investigate these changes and their association with macro-level fertility indicators in 21 countries. Between 2006-07 and 2018-19, societal consensus regarding the existence of optimal childbearing ages remained strong and became more in favour of later parenthood. Decomposition analyses show that these shifts were driven only partially by changes in population composition, supporting the idea that a general attitudinal change in favour of later childbearing is underway. We also find a trend towards gender convergence in upper age limits driven by the increasing social recognition of an age deadline for men's childbearing. Although shifts in perceived reproductive age windows occurred during periods of birth postponement, they corresponded only loosely to country-level changes in fertility.

This paper investigates the biological, socio-economic, and institutional factors shaping the individual risk of death during a major pre-industrial epidemic. We use a micro-demographic database for an Italian city (Carmagnola) during the 1630 plague to explore in detail the survival dynamics of the population admitted to the isolation hospital (lazzaretto). We develop a theoretical model of admissions to the lazzaretto, for better interpretation of the observational data. We explore how age and sex shaped the individual risk of death, and we provide a one-of-a-kind study of the impact of socio-economic status. We report an inversion of the normal mortality gradient by status for those interned at the lazzaretto. The rich enjoyed a greater ability to make decisions about their hospitalization, but this backfired. Instead, the poor sent to the lazzaretto faced a relatively low risk of death because they enjoyed better conditions than they would have experienced outside the hospital.

Effective government services rely on accurate population numbers to allocate resources. In Colombia and globally, census enumeration is challenging in remote regions and where armed conflict is occurring. During census preparations, the Colombian National Administrative Department of Statistics conducted social cartography workshops, where community representatives estimated numbers of dwellings and people throughout their regions. We repurposed this information, combining it with remotely sensed buildings data and other geospatial data. To estimate building counts and population sizes, we developed hierarchical Bayesian models, trained using nearby full-coverage census enumerations and assessed using 10-fold cross-validation. We compared models to assess the relative contributions of community knowledge, remotely sensed buildings, and their combination to model fit. The Community model was unbiased but imprecise; the Satellite model was more precise but biased; and the Combination model was best for overall accuracy. Results reaffirmed the power of remotely sensed buildings data for population estimation and highlighted the value of incorporating local knowledge.

We interrogate the proposition that men's attitudes have constrained the fertility transition in Cameroon, where fertility remains high and contraceptive use low despite much socio-economic progress. We use five Demographic and Health Surveys to compare trends in desired family size among young women and men and analyse matched monogamous couple data from the two most recent surveys to examine wives' and husbands' desires to stop childbearing and their relative influence on current contraceptive use. In 2018, average desired family size was 5.6 and 5.1, for young men and women respectively, and this difference (half a child) has not changed since 1998. Among matched couples, the proportions wanting to stop childbearing were similar in wives and their husbands, but wives perceived husbands to be much more pronatalist than themselves. Surprisingly, men's own reported preferences were more closely associated with contraceptive use than wives' perceptions of husbands' preferences. We discerned little evidence that men's attitudes have impeded reproductive change.

Chronic childhood undernutrition, known as stunting, is an important population health problem with short- and long-term adverse outcomes. Bangladesh has made strides to reduce chronic childhood undernutrition, yet progress is falling short of the 2030 Sustainable Development Goals targets. This study estimates trends in age-specific chronic childhood undernutrition in Bangladesh's 64 districts during 1997-2018, using underlying direct estimates extracted from seven Demographic and Health Surveys in the development of small area time-series models. These models combine cross-sectional, temporal, and spatial data to predict in all districts in both survey and non-survey years. Nationally, there has been a steep decline in stunting from about three in five to one in three children. However, our results highlight significant inequalities in chronic undernutrition, with several districts experiencing less pronounced declines. These differences are more nuanced at the district-by-age level, with only districts in more socio-economically advantaged areas of Bangladesh consistently reporting declines in stunting across all age groups.

Much less is known about the sex gap in lifespan variation, which reflects inequalities in the length of life, than about the sex gap in life expectancy (average length of life). We examined the contributions of age groups and causes of death to the sex gap in lifespan variation for 28 European countries, grouped into five European regions. In 2010-15, males in Europe displayed a 6.8-year-lower life expectancy and a 2.3-year-higher standard deviation in lifespan than females, with clear regional differences. Sex differences in lifespan variation are attributable largely to higher external mortality among males aged 30-39, whereas sex differences in life expectancy are due predominantly to higher smoking-related and cardiovascular disease mortality among males aged 60-69. The distinct findings for the sex gap in lifespan variation and the sex gap in life expectancy provide additional insights into the survival differences between the sexes.

Studies of childbearing across partnerships-having children with more than one partner-have generally focused on countries with relatively high separation rates. We complement this previous research with analyses for Italy using nationally representative, retrospective data and event-history techniques. This study offers three key findings. First, we detected a non-negligible share of childbearing across partnerships, although at substantially lower levels relative to other wealthy countries (5 per cent of parents aged 25-54 with at least two children). Second, multivariate analyses revealed an impressive similarity to the demographic correlates found elsewhere. Finally, we showed that childbearing across partnerships was initiated by the 'social vanguard' of new family behaviours but then diffused among the least well-off. Overall, this paper adds to the growing literature on childbearing across partnerships by showing the phenomenon to be demographically and sociologically relevant, even in countries with strong family ties and a limited diffusion of union dissolution.

The balance of men and women in society, captured by sex ratios, determines key social and demographic phenomena. Previous research has explored sex ratios mainly at birth and up to age five at national level, whereas we address rural-urban gaps in sex ratios for all ages. Our measures are based on the United Nations data on rural and urban populations by age and sex for 112 low- and middle-income countries in 2015. We show that rural sex ratios are higher than urban sex ratios among children and older people, whereas at working ages, urban areas are dominated by males. Our analysis suggests that the urban transition itself is not driving the gap in rural-urban sex ratios. Rather, internal migration seems to be key in shaping rural-urban sex ratio divergence in sub-Saharan Africa, while both internal migration and mortality differentials appear to be the predominant mechanisms driving sex ratio gaps in Latin America.
