To what extent do sociodemographic characteristics structure—or fail to structure—individual lifespans? Using U.S. Census data linked to administrative death records, we assess how well early‐adulthood social, economic, and demographic characteristics predict individual lifespan in a cohort of men born in 1910 and observed through their deaths between 1975 and 2005 ( <jats:italic>N</jats:italic> = 121,000). Despite large group‐level disparities, we find that sociodemographic characteristics measured in early adulthood explain less than two percent of the overall variation in individual lifespan. These findings reaffirm a central demographic regularity: variance in life expectancy between groups is small compared to variation in lifespan within groups. This highlights the fundamentally nondeterministic nature of how structural inequality shapes individual mortality.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"17 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147664019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider both weak and strong forms of social ties for both domestic and international trips. We also examine differences across male and female household members. Discrete time event history models reveal that migrant social ties predict making a first trip and are stronger for international versus domestic moves. Heat waves and storms/floods are positively associated with males making domestic trips and negatively associated with domestic trips among females. However, the effects are small and not moderated by social ties. In contrast, for male international moves, the effect of heat waves is conditional on the prevalence of ties to other international migrants. In communities with a strong history of international migration, the chance of making a first trip declines as heat waves intensify. Those from communities with a lower prevalence of international migration are more likely to make a first international trip as heat waves reach 15–25 days, after which the risk of migrating declines. Together, these results suggest that migrant networks attenuate, rather than amplify, the relationship between extreme weather and international migration.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"221 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147648948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a typology of displacement grounded in the tempo and form of conflict‐related insecurities—anticipatory, chronic, and imminent—and examines their consequences for women displaced from Myanmar to Thailand. Using survey data from 390 women, latent class analysis identified distinct pre‐displacement insecurity profiles and linked them to post‐displacement outcomes, including parallel insecurity profiles, mobility constraints, and labor exploitation. We also examined legal status and residence type as additional understudied yet policy‐relevant post‐displacement outcomes. Most respondents fled under anticipatory or chronic conditions rather than acute violence, underscoring that displacement from protracted conflict settings is often propelled by cumulative structural harm. Regression models showed that women who fled under chronic or imminent insecurity were substantially more likely to experience continued precarity after migration, including camp residence and insecure legal status. These findings highlight the need for temporal nuance in migration theory and humanitarian policy, recognizing conflict displacement as a prolonged process with enduring insecurities for women, families, and future generations, rather than a discrete event.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"119 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147617456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focusing on primary education, we demonstrate, first, that recent demographic trends have been highly polarizing for education systems worldwide. Persistent expansionary pressures burden some of the least‐resourced educational systems, whereas these pressures are reversing in wealthier countries with higher educational expenditures. Second, we document that global educational systems have adapted to narrow gaps in student‐ or child‐teacher ratios, despite polarizing demographic trends. Third, we show that system responses vary where school‐age cohorts are declining, although little is known about the impacts of system responses. And, finally, examining Korea, a case at the leading edge of the transition to population scarcity, we demonstrate that educational system consolidation can introduce new salience to geospatial hierarchies and the political economy of allocative decisions. Policy decentralization and popular resistance stymied a trend in which nonmetropolitan areas bore the brunt of primary school closures and teacher losses, while metropolitan areas saw increases in schools and teachers despite student declines. Research is sorely needed to understand how national educational systems are impacted by and adapting to the disparate forces of population growth and scarcity.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"19 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially a useful heuristic, the LLF concept now obscures more than it reveals, as it conflates vastly different demographic trajectories across an increasingly heterogeneous global landscape. We demonstrate that factors like international migration, mortality reduction, and human capital are powerful mediators of population futures, often more impactful than fertility rates alone. Using comparative cases, we show that similar LLF classifications can lead to starkly divergent outcomes. Consequently, we propose retiring the LLF framework in favor of a multidimensional demography that situates fertility within an integrated system of demographic and socioeconomic factors, enabling more nuanced and effective policy responses to contemporary population change.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"59 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147447242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This concept raises important demographic and sociological questions as to how this has happened, particularly in view of the long history of assimilation and integration theories, in which immigrant groups are hypothesized to become more similar to host society populations over time. In this study, we provide a demographic perspective, positioning immigration and integration as forces that influence population heterogeneity. We utilize a detailed dataset of population stocks and flows between 2011 and 2021 from Australia and develop a multiregional demographic model to quantify the contributions of immigration and integration to contemporary diversity. The results show how immigration drives diversification, giving rise to migrant and multidimensional diversity. Integration in terms of citizenship, language proficiency, occupational attainment, and homeownership is strongly evidenced and helps to shift the socioeconomic characteristics of foreign‐born populations and their children, though they do not have substantial impacts on measures of population diversity. These findings provide insights for theorizing and measuring the relationships between immigration and diversity, and their long‐term societal implications.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"81 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147447427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We discuss the particular characteristics of existing armed conflict datasets and the types of biases that may be present in data drawn from conflict‐affected areas. Further, we demonstrate how data and measurement choices can result in different conclusions and, if handled improperly, even spatial misclassification, bias, and spurious conclusions. Lastly, we illustrate some of these data and measurement choices in an empirical example where we assess the impact of conflict on women's contraceptive use in Nigeria. Using conflict event data from the Uppsala Conflict Data Program and health data from the Nigerian Demographic and Health Survey in 2018, we show how the relationship between exposure and outcomes varies across different spatiotemporal dimensions of conflict exposure measurement.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"9 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147447430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recognizing that delayed and declining marriage is the primary reason for low fertility in the region, we posit that marriage decisions are shaped by intentions or incentives (not) to have children. We evaluate this hypothesis using Japan as a case, a society where parenthood is an integral part of the “package” of normative family expectations accompanying marriage, especially for women. After confirming that attitudes toward marriage and fertility are strongly correlated, we estimate discrete‐time hazard models of first marriage using nationally representative longitudinal data. We find that, net of marriage desires, (1) women and men with no desire to have children marry significantly later than those who desire children, and (2) uncertain attitudes toward parenthood are also associated with later marriage for men, but not women. The link between negative or uncertain fertility desires and delayed marriage among men is partially explained by their lower engagement in efforts to find a marriage partner. These results provide insights for policy discussions about declining fertility in East Asia, especially concerns that pro‐natalist policies are mistargeted.","PeriodicalId":51372,"journal":{"name":"Population and Development Review","volume":"1 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147380784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
