Twentieth-Century Change in the Educational Costs of Adolescent Childbearing.

Although studies observe heterogeneity in the effects of adolescent childbearing on schooling, little is currently known about when this pattern emerged or how it changed across cohorts of women who lived in distinct periods of US history. This article identifies the potential origins of effect heterogeneity in the educational costs of adolescent childbearing and extends recent advances in causal inference to detect group differences in heterogeneity. The analysis applies this approach to four cohorts of women from the National Longitudinal Surveys (NLS) who entered adolescence before, during, and after expansive economic, demographic, and cultural change in the twentieth century. Results suggest that the educational costs of adolescent childbearing, as well as heterogeneity in those costs, increased for women in the latter half of the twentieth century, especially for millennial women born 1980-84. The authors conclude that midcentury social changes fundamentally altered the educational costs of adolescent childbearing for women.

Occupations and careers within organizations: Do organizations facilitate unequal wage growth?

Recent research suggests that occupations and organizations intersect during the formation of wage inequality. Using administrative data from the Netherlands, I investigate whether workers who are employed in different occupations experience unequal wage growth when staying in an organization. Results reveal that workers in professional and managerial positions realize larger wage growth than workers who work initially in lower-status occupations. After six years of staying at the same organization, predicted wage growth rates vary between 5.44% for production workers and 10.18% for technical professionals. The findings indicate that occupations compound present and future wage advantages at the organizational level. I test whether occupational sorting across organizations with differing pay quality mediates part of the occupation-based heterogeneity in wage growth. The results show that occupational sorting is marked but that sorting explains only up to around 8% of inequality in firm-internal wage growth between different occupational classes in the Dutch labor market.

When the Penny Drops: Understanding how social class influences speciality careers in the UK medical profession.

In the UK, the medical profession is socially exclusive and socially stratified as doctors from more advantaged backgrounds are more likely to train for specialities with more competitive entry. However, in research to date the causes and consequences of social stratification have been overlooked. We explore this subject here, drawing on a qualitative study comprising in-depth interviews with 30 medical students and doctors from less advantaged socio-economic backgrounds negotiating medical school and early careers. Using Bourdieu's 'theory of practice' we show how socialisation in the family and at school influences how aspirant medics from less advantaged backgrounds view the world, suggesting some inclination towards more community orientated careers, which may be less competitive. However, these tendencies are encouraged as they lack stocks of social, economic and cultural capital, which are convertible to power and position in the field. While allowing for both choice and constraint our core argument is that speciality outcomes are sometimes inequitable and potentially inefficient, as doctors from more advantaged backgrounds have privileged access to more competitive careers for reasons not solely related to ability or skill. Our main theoretical contribution is to literature in the sociology of medical education where ours is the first study to open-up the 'black box' of causal factors connecting medical students' resources on entering the field of education and training with speciality outcomes, though our findings also have important implications for practitioners, the profession and for patients. We discuss the implications for safe and effective healthcare and how this informs directions for future research.

The impact of austerity on children: Uncovering effect heterogeneity by political, economic, and family factors in low- and middle-income countries.

Which children are most vulnerable when their government imposes austerity? Research tends to focus on either the political-economic level or the family level. Using a sample of nearly two million children in 67 countries, this study synthesizes theories from family sociology and political science to examine the heterogeneous effects on child poverty of economic shocks following the implementation of an International Monetary Fund (IMF) program. To discover effect heterogeneity, we apply machine learning to policy evaluation. We find that children's average probability of falling into poverty increases by 14 percentage points. We find substantial effect heterogeneity, with family wealth and governments' education spending as the two most important moderators. In contrast to studies that emphasize the vulnerability of low-income families, we find that middle-class children face an equally high risk of poverty. Our results show that synthesizing family and political factors yield deeper knowledge of how economic shocks affect children.

Best for Whom? Heterogeneous Treatment Effects of Breastfeeding on Child Development.

The slogan "Breast is Best" has been popularized by medical organizations and parenting networks to extoll the benefits of breastfeeding, yet the causal effects are widely debated. Our study contributes to the debate by examining whether breastfeeding has differential effects based on the propensity to breastfeed, which is also known as causal effect heterogeneity. Prior studies attempt to isolate the causal effect of breastfeeding by netting out confounding characteristics, but we argue that the effects of breastmilk are unlikely to operate in a vacuum. The social forces that promote or constrain breastfeeding among different populations in American society can also shape its effects. Using rich intergenerational panel data from the NLSY79 Child and Young Adult cohort (n = 7902), we evaluate heterogeneous treatment effects in the relationship between breastfeeding and child development from ages 4 to 14 using stratification-multilevel propensity score models. We find that breastfeeding is associated with small benefits for behavioral development, math scores, and academic ability among those with the highest propensities to breastfeed. By contrast, its small benefits for reading comprehension and vocabulary are concentrated among children with the lowest propensities to breastfeed. Our findings suggest that the social process of selection into breastfeeding cannot be fully disentangled from its estimated effects. The social context not only shapes who breastfeeds in American society, but also who benefits most.

Stratified pathways to Italy's "latest-late" transition to adulthood.

During the last few decades, Western societies have undergone substantial social and demographic changes, and the transition to adulthood progressively moved from an early, contracted, and simple pattern to a late, protracted, and complex one. These trends have been extensively analyzed under the Second Demographic Transition framework, emphasizing the role of individual agency and ideational change. A growing parallel literature underlines social stratification, the gender revolution, and contextual opportunities as driving forces. This paper builds on this emerging literature to analyze trends of the transition to adulthood in Italy, a salient social and demographic context among the "lowest-low" fertility countries. Drawing from the European Social Survey 2018 data, I use Sequence Analysis to compute a taxonomy of ideal types of transition to adulthood and analyze their evolution across cohorts. These analyses show that the emergence of a late and protracted transition to adulthood, associated with "lowest-low" fertility levels, is stratified by gender and socioeconomic background. This study contributes to the growing literature on the social stratification of life course trajectories and the relevance of contextual opportunities and constraints by analyzing the transition to adulthood in a low-opportunity context from a longitudinal, stratified perspective.

Racial, Ethnic, Nativity, and Educational Disparities in Cognitive Impairment and Activity Limitations in the United States, 1998-2016.

Despite extensive research on cognitive impairment and limitations in basic activities of daily living, no study has investigated the burden of their co-occurrence (co-impairment). Using the Health and Retirement Study data and incidence-based multistate models, we study the population burden of co-impairment using three key indicators: mean age at onset, lifetime risk, and health expectancy. We examine patterns by gender, race, ethnicity, nativity, education, and their interactions for U.S. residents aged 50-100. Furthermore, we analyze what fractions of racial, ethnic, and nativity disparities in co-impairment are attributable to inequalities in educational attainment. Results reveal that an estimated 56% of women and 41% of men aged 50 will experience co-impairment in their remaining life expectancy. Men experience an earlier onset of co-impairment than women (74 vs. 77 years), and women live longer in co-impairment than men (3.4 vs. 1.9 years). Individuals who are Black, Latinx, and lower educated, especially those experiencing intersecting disadvantages, have substantially higher lifetime risk of co-impairment, earlier co-impairment onset, and longer life in co-impairment than their counterparts. Up to 75% of racial, ethnic, and nativity disparity is attributable to inequality in educational attainment. This study provides novel insights into the burden of co-impairment and offers evidence of dramatic disparities in the older U.S. population.

The Impact of Social Well-Being on Population Diet Nutritional Value and Antiradical Status.

The paper presents the result of assessing the antiradical status of consumers (in the context of Russia) in connection with their well-being. This approach is based on a multistage study, in which the results of sociological surveys were applied, as well as estimates of the antiradical potential (ARP) of diets obtained using neural networks, bootstrapping the chemical composition of diets, and calculating reference values using mathematical models. The paper presents data collected from residents living in the territories of at least 21 regions and cities of Russia: Magadan, Saint Petersburg, Moscow, Krasnodar, Lipetsk, Vladivostok, Novosibirsk, Omsk, Voronezh, etc. A total of 1001 people were interviewed, which, according to our calculations, gives a margin of error in value of approximately 3.1%. To calculate the lack of vitamins in the diets of residents of the Russian Federation, data on the chemical composition of food products from the FNDDS database were used. The assessment of dietary habits showed a lack of vitamins below the recommended level in 73% of Russians for vitamin D, 59% for retinol, 38% for ß-carotenes, 13% for vitamin E, and 6% for ascorbic acid. The study showed that at least 36% of the Russian population has a low antiradical status, while it was found that "poor" consumers are more likely to consume economically more expensive foods (in terms of their nutritional value). The "poor" segments of the population consume 180-305% more canned food and 38-68% more sweet carbonated drinks than other social groups, but their consumption of vegetables is 23-48% lower. On the contrary, "wealthy" consumers consume 17-25% more complex (varied) dishes, 10-68% more fresh vegetables, and 8-39% more fish. From the obtained values it follows that consumers with low levels of ARP in their diets are in a group with an increased probability of a number of "excess" diseases (diseases of the cardiovascular system, obesity, etc.). In general, the ARP values of food consumed for low-income segments of the population were 2.3 times lower (the ratio was calculated as the percentage of consumers below the level of 11,067 equivalents necessary for the disposal of free radicals generated in the human body per day) than for those who can afford expensive food (consumers with high income). A simple increase in consumption of unbalanced foods, in our opinion, will only contribute to the entry of these consumers into the "average diet trap". All this makes it imperative to develop comprehensive measures to create a new concept of public catering; otherwise, we can expect a reduction in both the health of the population and the performance of the economy of the whole country.

Recovering the Vocational Self?: Service User Accounts of Barriers to Work and School and the Role of Early Psychosis Services in Supporting Career Development.

Vocational recovery is frequently identified as a primary goal of specialized early intervention in psychosis services (EIS). However, few studies have investigated the multi-level impacts of psychosis and its social sequelae on emerging vocational identities and mechanisms by which EIS may contribute to longer-term career development. The goal of this study was to deepen our understanding of the experiences of young adults with early psychosis during and following discharge from EIS as they relate to vocational derailment, identity and career development. We conducted in-depth interviews with 25 former EIS recipients and five family members (N = 30). Interviews were analyzed using modified grounded theory, with an orientation to generating a rich, theory informed understanding young people's experiences. Approximately half of the participants in our sample were not in employment, education, or training (NEET) and had applied for or were receiving disability benefits (SSI/SSDI). Among those participants who were working, the majority reported short-term, low-wage work. Thematic findings elucidate factors underlying the erosion of vocational identity, as well as ways in which both participant-reported vocational service characteristics and socioeconomic background shape different pathways to college, work and/or disability benefits both during and following discharge from EIS. Findings underscore the need for additional research on vocational identity among youth and young adults with early psychosis and the development and evaluation of interventions designed to support career development, address social and structural barriers to education and training, and foster long-term socioeconomic mobility.

Social stratification in networks: insights from co-authorship networks.

It has been observed that real-world social networks often exhibit stratification along economic or other lines, with consequences for class mobility and access to opportunities. With the rise in human interaction data and extensive use of online social networks, the structure of social networks (representing connections between individuals) can be used for measuring stratification. However, although stratification has been studied extensively in the social sciences, there is no single, generally applicable metric for measuring the level of stratification in a network. In this work, we first propose the novel Stratification Assortativity (StA) metric, which measures the extent to which a network is stratified into different tiers. Then, we use the StA metric to perform an in-depth analysis of the stratification of five co-authorship networks. We examine the evolution of these networks over 50 years and show that these fields demonstrate an increasing level of stratification over time, and, correspondingly, the trajectory of a researcher's career is increasingly correlated with her entry point into the network.

Socially stratified associations between self-employment and health among Chilean older people.

Non-standard forms of employment, such as self-employment, are among the most prevalent routes for older people to access the workforce. While the financial benefits of any form of self-employment in later life have been widely acknowledged, less is known about their impact on health. This study explores the association between self-employment and 16 health outcomes among older people with different social stratification characteristics in Chile, a developing country experiencing rapid population ageing. We rely on a rich representative life history survey of Chilean men and women between the ages 65 and 75 years (N = 802) living in the capital Santiago, weighted sequence analysis to reconstruct employment histories and weighted regression analysis to measure the association between self-employment and health in later life. All our analyses are adjusted by both individual lifetime health indicators and employment trajectories. Our results show that being self-employed relative to not working is positively associated with health in seven out of 16 outcomes. More surprisingly, those in a self-employment position seem to enjoy better health outcomes, particularly among the less educated and lower-income levels. These stratified associations raise questions about how these individuals enjoy better health despite facing adverse social conditions.

Scar effects of unemployment on generalised social trust: The joint impact of individual and contextual unemployment across Europe.

How does unemployment affect generalised social trust? A growing body of work has analysed the scar effects of unemployment on trust. However, this literature has not yet addressed the moderating role of contextual unemployment. In this article, we extend a theoretical framework positing that individual and contextual unemployment depress generalised social trust and formulate competing hypotheses on their interaction. We test these hypotheses relying on Rounds 4-9 (2008-2018) of the European Social Survey, for up to 29 countries and 227 regions. Results from three-level multilevel models indicate that individual and contextual unemployment are associated with lower trust, although at the macro-level this holds only for cross-sectional unemployment. At the macro-micro level, we find that lower cross-sectional unemployment rates powerfully exacerbate the individual association, while the latter becomes not significant at higher cross-sectional rates. These findings highlight that individual and contextual unemployment are central to illuminate social trust patterns.

Research on the healthy life expectancy of older adult individuals in China based on intrinsic capacity health standards and social stratification analysis.

Background: Based on the health standard of intrinsic capacity, this paper conducts an empirical study on the healthy life expectancy of older adult individuals aged 60 and older in China and analyzes the health inequities associated with different social characteristics to provide a reference for improving care for the older adult in China. Methods: Data from the China Health and Retirement Longitudinal Study from 2011 to 2015 were used to evaluate the intrinsic capacity level of older adult individuals, and the multistate life table method was used to measure the healthy life expectancy of older adult individuals in China with the help of IMaCH software. Based on the theory of social stratification, the health inequality between older adult individuals in different social classes was analyzed in three dimensions: residence, income and education level. Results: The calculation results show that the average life expectancy of the older adult in China at age 60 is 21.07 years, the healthy life expectancy is 16.89 years, and the healthy life expectancy accounts for 80.2% of the average life expectancy. The healthy life expectancy of older adult individuals with different social characteristics in China shows significant differences, and the healthy life expectancy of older adult individuals who are male, live in urban environments, have high levels of education and have middle- to high-income levels is significantly better than that of older adult individuals who are female, live in rural areas, have low levels of education and income. Conclusion: Healthy life expectancy measured by intrinsic capacity as the health standard has a certain reference value, which reflects the overall health level of older adult individuals in China and expands the transformation and multidimensional understanding of the healthy thinking of older adult individuals in China. The analysis by social stratification reflects the large health inequities that exist in the older adult population in China.

Secondary Education and Class Stratification: Understanding the Hierarchy of Sexuality Education in a Chinese Vocational High School.

The discussion of sexuality education has a long history in China since the onset of modernisation in the early 20th century. Sexuality education has also existed in China's educational system for a long time but in various forms. However, the discussions regarding students' experiences and the influence of social stratification in China's particular social context are still limited. From March to September 2019, the author visited an academic high school (pugao) and a vocational high school (zhigao) in Tianjin, China, to gain first-hand data to understand young people's sexuality education experiences. In this paper, the author specifically paid attention to China's social class, a rarely discussed topic in China's society. She also tried to listen to the voices of young people and schoolteachers and help them to be heard. By presenting the insights from schoolteachers, students, as well as the materials from a nationally approved textbook, the author conducted a thematic analysis about how social class influences young people's sexuality education experiences in secondary education in China.

Childhood disability, social class and social mobility: A neglected relationship.

Disability theorists have long highlighted the role of institutional, social, and environmental barriers in constructing disability, emphasizing its parallels with other socially constructed axes of stratification. However, despite theoretical developments toward sociological understandings of disability, social stratification and life-course research have largely neglected childhood disability as a social division. As a result, we still know little surrounding the socio-economic attainment of disabled children and young people. Drawing on Next Steps data, this research note highlights stark overlooked inequalities between disabled and non-disabled young people's activity status and social mobility in early adulthood. We specifically focus on the importance of social class for disabled young people's outcomes, emphasizing the need for intersectional analyses of disability inequalities. We also outline longitudinal survey data enhancements necessary for life-course research on childhood disability and its intersections.

Social Group Differences in Influencing Factors for Chinese Urban Residents' Subjective Well-Being: From the Perspective of Social Stratification.

With the great pressure of modern social life, the problem of residents' subjective well-being has attracted scholars' attention. Against the background of institutional transformation, China has a special social stratification structure. The socio-economic resources and living needs of different social classes are different, resulting in differences in the level of subjective well-being and the influencing factors for this. Taking Guangzhou as an example, based on the data of a household survey conducted in 2016, this paper obtains the social hierarchical structure through two-step clustering, and explores the differences between influencing factors for subjective well-being using multiple linear regression models. The clustering results divided Guangzhou urban residents into four classes: retirees, white-collar workers outside the system, manual workers and white-collar workers inside the system. The subjective well-being of white-collar workers inside the system and manual workers is high. The subjective well-being of white-collar workers outside the system is below the average value, and retirees have poor subjective well-being. The results of the regression analysis show that the subjective well-being of all social classes could be improved by active participation in fitness exercises, harmonious neighborhood relationships and a central residential location. Health-related factors such as physical health, sleeping time and density of neighborhood medical facilities, have a significant impact on manual workers' subjective well-being. An increase in the density of neighborhood leisure facilities could help to improve the subjective well-being of white-collar workers outside the system. However, this would inhibit the subjective well-being of white-collar workers within the system. By revealing the differences in influencing factors for different social groups' subjective well-being, the research conclusions could provide a reference for the formulation of targeted policies and measures to improve residents' subjective well-being in urban China.

Ethno-racial stratification in the mortgage market: The role of co-applicants.

Unequal access to homeownership is central to ethno-racial stratification. Ample research demonstrates large ethno-racial disparities that exist in access and outcomes throughout the mortgage process at both the individual and neighborhood levels. The underlying assumption in most of these studies is that the couples applying for a mortgage are ethno-racially homogenous. However, the ethno-racial stratification structure is unclear when examining interracial couples in the mortgage market. This paper draws on annual data from the Home Mortgage Disclosure Act (HMDA) from 2010 to 2017 to assess variation in ethno-racial disparities in loan outcomes associated with different ethno-racial couplings. I show that ethno-racial disparities in loan outcomes vary tremendously when factoring the ethno-racial identity of the co-applicant. Interracial couples involving a black or Latino co-applicant are more likely to experience a high-cost loan or be denied a mortgage than mono-racial white couples. The results for Asian co-applicants vary, depending on the adverse loan outcome. When comparing interracial couples to mono-racial couples, the observed lending pattern provides evidence of a tri-racial hierarchy in the mortgage market.

Economic inequalities in contemporary rural China: How does political capital matter?

To assess how the transition from state socialism to a market economy has impacted the social stratification order in China, some prior studies have debated whether the economic privileges of the political redistributors have declined relative to the emerging market elites, while others have examined the coevolution between the two in urban institutional contexts. This study provides new insights into how political capital influences economic inequalities in contemporary rural China by revisiting informal social institutions. Drawing upon a unique nationally representative household survey and using surname sharing with the village cadres to infer shared lineage membership, we find that lineage-based political ties help rural Chinese households to materialize income as well as asset advantages over fellow villagers bereft of such ties. Furthermore, the economic privileges of political connections are larger in villages with lineage groups than those without, and larger for villages of more frequent kin interactions than those of less frequent kin interactions. Our results extend prior findings on the coevolution between political and market elites by going beyond formal institutions and examining grassroots-level evidence in contemporary rural communities.

Social stratification in meaningful work: Occupational class disparities in the United Kingdom.

Sociologists have long been interested in the meaning workers derive from their jobs. The issue has garnered increasing academic and policy attention in recent years with the concept of "meaningful work," yet little is known about how social stratification relates to access to it. This paper addresses this issue by exploring how the meaningfulness of jobs-as rated by their incumbents-is stratified across classes and occupations in a national survey of 14,000 working adults in the United Kingdom. It finds modest differentials between classes, with those in routine and manual occupations reporting the lowest levels of meaningfulness and those in managerial and professional occupations and small employers and own account workers reporting the highest levels. Detailed job attributes (e.g., job complexity and development opportunities) explain much of the differences in meaningfulness between classes and occupations, and much of the overall variance in meaningfulness. The main exception is the specific case of how useful workers perceive their jobs to be for society: A handful of occupations relating to health, social care, and protective services which cut across classes stand out from all other occupations. The paper concludes that the modest stratification between classes and occupations in meaningful work is largely due to disparities in underlying job complexity and development opportunities. The extent to which these aspects of work can be improved, and so meaningfulness, especially in routine and manual occupations, is an open, yet urgent, question.

Heterogeneity in Family Life Course Patterns and Intra-Cohort Wealth Disparities in Late Working Age.

Considering soaring wealth inequalities in older age, this research addresses the relationship between family life courses and widening wealth differences between individuals as they age. We holistically examine how childbearing and marital histories are associated with personal wealth at ages 50-59 for Western Germans born between 1943 and 1967. We propose that deviations from culturally and institutionally-supported family patterns, or the stratified access to them, associate with differential wealth accumulation over time and can explain wealth inequalities at older ages. Using longitudinal data from the German Socio-Economic Panel Study (SOEP, v34, waves 2002-2017), we first identified typical family trajectory patterns between ages 16 and 50 with multichannel sequence analysis and cluster analysis. We then modelled personal wealth ranks at ages 50-59 as a function of family patterns. Results showed that deviations from the standard family pattern (i.e. stable marriage with, on average, two children) were mostly associated with lower wealth ranks at older age, controlling for childhood characteristics that partly predict selection into family patterns and baseline wealth. We found higher wealth penalties for greater deviation and lower penalties for moderate deviation from the standard family pattern. Addressing entire family trajectories, our research extended and nuanced our knowledge of the role of earlier family behaviour for later economic wellbeing. By using personal-level rather than household-level wealth data, we were able to identify substantial gender differences in the study associations. Our research also recognised the importance of combining marital and childbearing histories to assess wealth inequalities.
