Research on the effects of school composition tends to focus on how it shapes school achievement. In this study, we instead examine how school composition shapes children's educational aspirations, given their achievement, and if children from different socio-economic backgrounds are affected differently. We apply school-fixed effects on Swedish register data, including all 9th-grade students from 2013 to 2017. Being exposed to a high share of low-achieving schoolmates increases the likelihood of applying for academics instead of vocational tracking across socio-economic backgrounds. In contrast, the share of high-achieving schoolmates is negatively associated with academic tracking only for high-SES children. Being exposed to peers with highly educated parents increases the likelihood of applying for academic tracking for low-SES children, whereas the effect is weaker or even negative for some of the high-SES groups. Together, our results suggest that the academic decisions of both high- and low-SES children could benefit from a less segregated school environment.

This study investigates the geographical distribution of highly educated individuals in Sweden, examining where they live and where they come from. The study utilises longitudinal individual data on individuals born between 1972 and 1984 and illustrates educational disparities between Swedish regions based on where the individuals lived at age 18 and at age 33. The geographical units are regions, allowing for a comprehensive analysis. We show that educational disparities are smaller when described using region of origin compared to region of residence. High levels of educational attainment in urban areas are thus largely due to the immigration of educated individuals. Conversely, rural regions experience brain drain, losing educated individuals to cities. By comparing the two perspectives, we can show that brain drain does not increase over time. Based on region of origin, higher education has become more geographically equitable over the period studied. Importantly, however, increasingly highly educated people have grown up in Stockholm. If that trend continues, it may become difficult in the future for highly educated people from the rest of Sweden to compete for jobs in Stockholm.

Older peoples ability to thrive independently of their adult children is an important feature of a universalistic welfare system. However, population ageing puts this notion under stress. In separate multinomial logistic regression models for older men and women, we examined whether adult childrens gender, number and proximity were associated with older parents relocations into residential care facilities, and whether the effects of these childrens characteristics on older parents institutionalisation vary by parents severe health problems, operationalised as closeness to death - specifically, dying within the two-year observation period. Analyses were based on the Swedish register data between 2014 and 2016 (N = 696,007 person-years). Older parents with at least one co-resident child were less likely to move or become institutionalised than those without a co-resident child. We did not find a relationship between older adults institutionalisation and the closest childs gender. The negative effect of having a non-resident child living nearby on the likelihood of becoming institutionalised was more pronounced for mothers than fathers. Having a child nearby decreased the likelihood of moving to an institution more for mothers who had severe health problems than for those in better health. We found no evidence of a relationship between number of children and likelihood of institutionalisation.

This study investigates if neighbourhoods can alter the strong relationship between parental background and childrens adult outcomes. In particular, we examine if neighbourhood effects are heterogeneous in such a way that they are particularly important for children from disadvantaged backgrounds, and if school quality has a mediating effect in this equation. Using register data and individualized neighbourhoods, we follow five full birth cohorts of individuals born from 1983 to 1987. We examine the interaction between social background and neighbourhoods in shaping (i) the risk of children relying on social welfare when they are aged 30, and (ii) the probability of belonging to the highest income decile at age 30-34. Growing up in a resource-rich neighbourhood is associated with better life outcomes. Contrary to what several neighbourhood theories predict, we find that neighbourhood effects operate similarly regardless of social background. Differences in peer composition of schools does not explain these local neighbourhood effects, whereas own school results attenuate neighbourhood effects substantially. Our findings are in contrast to results from the United States studies but are in line with historical Swedish studies; and contribute to further disentangling the various mechanisms through which the neighbourhood operates.

Background: Studies on risk factors for severe COVID-19 in people of working age have generally not included non-working persons or established population attributable fractions (PAFs) for occupational and other factors. Objectives: We describe the effect of job-related, sociodemographic, and other exposures on the incidence, relative risks and PAFs of severe COVID-19 in individuals aged 18–64. Methods: We conducted a registry-based study in Swedish citizens aged 18–64 from 1 January 2020 to 1 February 2021 with respect to COVID-19-related hospitalizations and death. Results: Of 6,205,459 persons, 272,043 (7.5%) were registered as infected, 3399 (0.05%) needed intensive care, and 620 (0.01%) died, with an estimated case fatality rate of 0.06% over the last 4-month period when testing was adequate. Non-Nordic origin was associated with a RR for need of intensive care of 3·13, 95%CI 2·91–3·36, and a PAF of 32·2% after adjustment for age, sex, work, region and comorbidities. In a second model with occupation as main exposure, and adjusted for age, sex, region, comorbidities and origin, essential workers had an RR of 1·51, 95%CI, 1·35–1·6, blue-collar workers 1·18, 95%CI 1·06–1·31, school staff 1·21, 95%CI 1·01–1·46, and health and social care workers 1·89, 95%CI 1·67–2·135) compared with people able to work from home, with altogether about 13% of the PAF associated with these occupations. Essential workers and blue-collar workers, but no other job categories had higher risk of death, adjusted RRs of 1·79, 95%CI 1·34–2·38 and 1·37, 95%CI 1·04–1·81, with adjusted PAFs of altogether 9%. Conclusion: Among people of working age in Sweden, overall mortality and case fatality were low. Occupations that require physical presence at work were associated with elevated risk of needing intensive care for COVID-19, with 14% cases attributable to this factor, and 9% of deaths. © 2022 The Authors

Objective This study examines the roles of commitment and gender equality for marriage formation in a highly individualized and gender-egalitarian context. Background Marriage is commonly perceived as a more committed form of union than cohabitation. Individualization perspectives propose that this discourages marriage formation, whereas gender perspectives suggest that this is only the case for couples living in egalitarian lives. Method The roles of marriage attitudes and gender equality for marriage formation are studied among 1085 cohabiting men and women born in Sweden in 1968-1980 using the 2003 wave of the Young Adult Panel Study, which is based on a stratified random sample. The authors examine how cohabitants perceive: (1) the level of commitment in cohabitation versus marriage and (2) the division of housework in their current relationship, and link these factors to population register data showing the individuals likelihood of marrying in 2004-2007. Results Cohabitants are more likely to marry if they believe that marriage indicates relationship seriousness, but less likely if they see a marriage as more difficult to leave than cohabitation. Gender equality, measured as satisfaction with the division of housework, appears to be positively related to marriage formation. Whether perceiving marriage as a particularly committed form of union is more positive for marriage formation among gender-equal couples remains unclear, as the direction of the findings varies and statistical power is low. Conclusion Even in a highly individualized context, cohabitants seek certain forms of commitment through marriage. Gender equality plays a role, but needs further investigation.

Educational gradients in parental leave length are opposite for women and men: highly educated women return to work faster than those with low education while highly educated men are absent longer than less educated men. Explanations for the opposite gradients are typically made at the individual- or couple-level. To date, no quantitative study has documented whether the opposite educational gradients hold also within workplaces. In this study, we use employer-employee matched Swedish register data with fixed-effects models to examine whether the educational gradient applies also among co-workers in the same workplace. The results show that three-quarters of the educational effect typically attributed to the individual father disappeared when comparing fathers within workplaces. The educational gradient of mothers remained largely unchanged. These findings provide the first population-level evidence for the primacy of the workplace in determining fathers care choices.

Background Exposure to many contacts is the main risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, while risk of serious disease and death is chiefly determined by old age and comorbidities. Relative and population-attributable fractions (PAFs) of multiple medical and social exposures for COVID-19 outcomes have not been evaluated among older adults. Objectives We describe the effect of multiple exposures on the odds of testing positive for the virus and of severe disease (hospital care or death) and PAFs in Swedish citizens aged 55 years and above. Methods We used national registers to follow all citizens aged 55 years and above with respect to (1) testing positive, (2) hospitalization, and (3) death between 31 January 2020 and 1 February 2021. Results Of 3,410,241 persons, 156,017 (4.6%, mean age 68.3 years) tested positive for SARS-CoV-2, while 35,999 (1.1%, mean age 76.7 years) were hospitalized or died (12,384 deaths, 0.4%, mean age 84.0 years). Among the total cohort, the proportion living without home care or long-term care was 98.8% among persons aged 55-64 and 22.1% of those aged 95 and above. After multiple adjustment, home care and long-term care were associated with odds ratios of 7.9 (95% confidence interval [CI] 6.8-9.1) and 22.5 (95% CI 19.6-25.7) for mortality, with PAFs of 21.9% (95% CI 20.9-22.9) and 33.3% (95% CI 32.4-34.3), respectively. Conclusion Among Swedish residents aged 55 years and above, those with home care or long-term care had markedly increased risk for COVID-19 death during the first year of the pandemic, with over 50% of deaths attributable to these factors.

It is a matter of debate whether free school choice should lead to higher or lower levels of school segregation. We investigate how school choice opportunities affect school segregation utilizing geocoded Swedish population register data with information on 13 cohorts of ninth graders. We find that local school choice opportunities strongly affect the sorting of students across schools based on the parents country of birth and level of education. An increase in the number of local schools leads to higher levels of local segregation net of stable area characteristics, and time-varying controls for population structure and local residential segregation. In particular, the local presence of private voucher schools pushes school segregation upwards. The segregating impact of school choice opportunities is notably stronger in native areas with high portions of highly educated parents, and in areas with low residential segregation. Our results point to the importance of embedding individual actors in relevant opportunity structures for understanding segregation processes.

Objectives To evaluate the role of language proficiency and institutional awareness in explaining excess COVID-19 mortality among immigrants. Design Cohort study with follow-up between 12 March 2020 and 23 February 2021. Setting Swedish register-based study on all residents in Sweden. Participants 3 963 356 Swedish residents in co-residential unions who were 30 years of age or older and alive on 12 March 2020 and living in Sweden in December 2019. Outcome measures Cox regression models were conducted to assess the association between different constellations of immigrant-native couples (proxy for language proficiency and institutional awareness) and COVID-19 mortality and all other causes of deaths (2019 and 2020). Models were adjusted for relevant confounders. Results Compared with Swedish-Swedish couples (1.18 deaths per thousand person-years), both immigrants partnered with another immigrant and a native showed excess mortality for COVID-19 (HR 1.43; 95% CI 1.29 to 1.58 and HR 1.24; 95% CI 1.10 to 1.40, respectively), which translates to 1.37 and 1.28 deaths per thousand person-years. Moreover, similar results are found for natives partnered with an immigrant (HR 1.15; 95% CI 1.02 to 1.29), which translates to 1.29 deaths per thousand person-years. Further analysis shows that immigrants from both high-income and low-income and middle-income countries (LMIC) experience excess mortality also when partnered with a Swede. However, having a Swedish-born partner is only partially protective against COVID-19 mortality among immigrants from LMIC origins. Conclusions Language barriers and/or poor institutional awareness are not major drivers for the excess mortality from COVID-19 among immigrants. Rather, our study provides suggestive evidence that excess mortality among immigrants is explained by differential exposure to the virus.
