Uptake of cash benefits among children with a disability in Norway: The role of parental socioeconomic characteristics and immigrant background

AbstractCaring for a disabled child involves both indirect and direct economic costs, which in turn may create a financial burden for the family. Using Norway as a case, we examine if public compensatory measures reach those most in need, by assessing whether socioeconomic disadvantages and immigrant background impact adversely on the uptake of a nationally available cash benefits eligible for parents caring for a child with a disability. We take advantage of national administrative register data on children with a selection of well‐defined diagnoses born between 2009 and 2017 (N = 14,469). Our results show nonnegligible, but relatively minor, social inequalities in the uptake of cash benefits related to socioeconomic and immigrant background. Our findings indicate that this state's financial support seems to reach those most in need. However, it is essential to deepen our understanding of how socioeconomic and immigrant backgrounds influence access to and utilization of municipal healthcare services. Notably, the application process for these services often involves a greater degree of discretion on the part of welfare professionals. Further research is needed to illuminate the nuanced dynamics of these factors in the context of accessing healthcare services at the local level.

School leadership and students’ decisions about further education: exploring the roles of goal setting and school socioeconomic composition

ABSTRACT This study focuses on the relationship between various leadership goal setting and students’ decisions about further education in the context of the Danish educational system. Furthermore, the potential of school leadership to reduce social disparities in such decisions is explored. The data set is based on repeated measurements of school leaders’ attitudes and practices from 819 schools over 4 years, merged with administrative register data. Multilevel multinomial logistic regression and two-way fixed effects multinomial regression were applied. We find no relationship between achievement goals and educational decisions. Depending on modeling choices, results indicate that leadership goal setting concerning transition is associated with a small increase in the chance of students choosing the academic track, and the goal of promoting citizenship among students was associated with a slightly higher probability of choosing the vocational track. Furthermore, transition goals moderate the relationship between school socioeconomic status and students’ probability of choosing the academic track.

Variation in Excess Mortality Across Nursing Homes in the Netherlands During the COVID-19 Pandemic

ObjectivesNursing home residents constituted a vulnerable population during the COVID-19 pandemic, and half of all cause-attributed COVID-19 deaths occurred within nursing homes. Yet, given the low life expectancy of nursing home residents, it is unclear to what extent COVID-19 mortality increased overall mortality within this population. Moreover, there might have been differences between nursing homes in their ability to protect residents against excess mortality. This article estimates the number of excess deaths among Dutch nursing home residents during the pandemic, the variation in excess deaths across nursing homes, and its relationship with nursing home characteristics. DesignRetrospective, use of administrative register data. Setting and ParticipantsAll residents (N = 194,432) of Dutch nursing homes (n = 1463) in 2016-2021. MethodsWe estimated the difference between actual and predicted mortality, pooled at the nursing home level, which provided an estimate of nursing home–specific excess mortality corrected for resident case-mix differences. We show the variation in excess mortality across nursing homes and relate this to nursing home characteristics. ResultsIn 2020 and 2021, the mortality probability among nursing home residents was 4.0 and 1.6 per 100 residents higher than expected. There was considerable variation in excess deaths across nursing homes, even after correcting for differences in resident case mix and regional factors. This variation was substantially larger than prepandemic mortality and was in 2020 related to prepandemic spending on external personnel and satisfaction with the building, and in 2021 to prepandemic staff absenteeism. Conclusions and ImplicationsThe variation in excess mortality across nursing homes was considerable during the COVID-19 pandemic, and larger compared with prepandemic years. The association of excess mortality with the quality of the building and spending on external personnel indicates the importance of considering differences across nursing home providers when designing policies and guidelines related to pandemic preparedness.

A Population-Based Matched Cohort Study of Digestive System Cancer Incidence and Mortality in Individuals With and Without Inflammatory Bowel Disease.

To study digestive system cancer risks in individuals with inflammatory bowel diseases (IBDs) in the biologic era. We used population-level administrative and cancer registry data from Ontario, Canada, (1994-2020) to compare people with IBD to matched controls (1:10 by sex and birth year) on trends in age-sex standardized cancer incidence and risk ratios of incident cancers and cancer-related deaths. Among 110,919 people with IBD and 1,109,190 controls, colorectal cancer incidence (per 100,000 person-years) declined similarly in people with ulcerative colitis (average annual percentage change [AAPC] -1.81; 95% confidence interval [CI] -2.48 to -1.156) and controls (AAPC -2.79; 95% CI -3.44 to -2.14), while small bowel cancer incidence rose faster in those with Crohn's disease (AAPC 9.68; 95% CI 2.51-17.3) than controls (AAPC 3.64; 95% CI 1.52-5.80). Extraintestinal digestive cancer incidence rose faster in people with IBD (AAPC 3.27; 95% CI 1.83-4.73) than controls (AAPC -1.87; 95% CI -2.33 to -1.42), particularly for liver (IBD AAPC 8.48; 95% CI 4.11-13.1) and bile duct (IBD AAPC 7.22; 95% CI 3.74-10.8) cancers. Beyond 2010, the incidences (and respective mortality rates) of colorectal (1.60; 95% CI 1.46-1.75), small bowel (4.10; 95% CI 3.37-4.99), bile duct (2.33; 95% CI 1.96-2.77), and pancreatic (1.19; 95% CI 1.00-1.40) cancers were higher in people with IBD. Cancer incidence is declining for colorectal cancer and rising for other digestive cancers in people with IBD. Incidence and mortality remain higher in people with IBD than controls for colorectal, small bowel, bile duct, and pancreatic cancers.

Implications of Childhood Autism Spectrum Disorder for Maternal Employment: United States vs. Norway

ObjectivesA country’s social welfare system may play an important role in maternal employment. This study compared the labor market participation of mothers of children within the United States (U.S.) and Norway to examine whether the child’s age and severity of the ASD affected mothers’ employment differently between the two countries.MethodsThe 2019 National Survey of Children’s Health was used for the U.S. analysis, and the 2019 administrative register data were used for the Norwegian analysis. A logit model was used to analyze the impact of a child’s age and ASD severity on maternal employment in the U.S. and Norway. We presented the results as average marginal effects obtained from the logistic regression analyses.ResultsAfter adjusting for mothers’ sociodemographic variables and the child’s age, U.S. mothers of children with mild ASD and moderate/severe ASD had respectively 12 and 25% points lower probability of being employed than U.S. mothers of children without special health care needs. In Norway, mothers of children with moderate/severe ASD had a 13% points lower probability of employment than mothers without special health care needs. The probability of being employed for mothers caring for a child with ASD was significantly greater as the child got older in both countries.Conclusions for PracticeThe employment gap was more substantial in the U.S. than in Norway. A general high employment participation rate among women and an elaborated welfare state and policy package seem to benefit employment among mothers of children with ASD in Norway.

Fertility Decline in Iceland, 2013-2022: Trends and Structures

Iceland is one of the Western countries that have experienced an unexpected fertility decrease in the 2010s. In this study, the aggregate Icelandic fertility decline is dissected to explore which fertility components are the main drivers behind the decline since 2010 in order to better understand whether the development is associated with compositional changes or linked to changes such as increased propensities of childlessness and decreased propensities to have another child. As such, it contributes empirical evidence to ongoing theorisation within current fertility debates. Official administrative register data are analysed by means of event-history analysis. Findings are presented as parity-specific birth risks and in the form of Kaplan-Meier estimates of synthetic period-based cohorts of women and men progressing to parity one over calendar years. In terms of results, we find that the fertility decline was concentrated around first births, and the decline can principally be attributed to women under the age of thirty. Propensities to remain childless have increased slightly since 2013, while there were no declines in the intensities to have a second and a third child. Hence, the development in Iceland appears to be driven by clear postponement of parenthood but not altered childbearing behaviour in terms of propensities to have a second and a third child. Results do not necessary contradict theories under the umbrella of the gender-relations framework, but they highlight the importance of exploring other factors impacting the transition to parenthood, such as perceived global and welfare uncertainties. Socioeconomic differentials in first-birth fertility and factors affecting postponement and ultimate childlessness should be explored further, as well as short-term developments in higher-order birth intensities during adverse circumstances, such as the 2008 economic crisis and the Covid-19 pandemic, during which periods the third-birth intensities increased.

Excess mortality in Denmark, Finland, Norway and Sweden during the COVID-19 pandemic 2020-2022.

The Nordic countries represent a unique case study for the COVID-19 pandemic due to socioeconomic and cultural similarities, high-quality comparable administrative register data and notable differences in mitigation policies during the pandemic. We aimed to compare weekly excess mortality in the Nordic countries across the three full pandemic years 2020-2022. Using data on weekly all-cause mortality from official administrative registers in Denmark, Finland, Norway and Sweden, we employed time series regression models to assess mortality developments within each pandemic year, with the period 2010-2019 used as reference period. We then compared excess mortality across the countries in 2020-2022, taking differences in population size and age- and sex-distribution into account. Results were age- and sex-standardized to the Danish population of 2020. Robustness was examined with a variety of sensitivity analyses. While Sweden experienced excess mortality in 2020 [75 excess deaths per 100 000 population (95% prediction interval 29-122)], Denmark, Finland and Norway experienced excess mortality in 2022 [52 (14-90), 130 (83-177) and 88 (48-128), respectively]. Weekly death data reveal how mortality started to increase in mid-2021 in Denmark, Finland and Norway, and continued above the expected level through 2022. Although the Nordic countries experienced relatively low pandemic excess mortality, the impact and timing of excess mortality differed substantially. These estimates-arguably the most accurate available for any region in capturing pandemic-related excess deaths-may inform future research and policy regarding the complex mortality dynamics in times of a health crisis such as the COVID-19 pandemic.

Is there a link between health care utilisation and subjective well-being? An exploratory study among older Danes.

While extensive research has explored the influence of traditional factors such as socioeconomic position on health care utilisation, the independent role of an individual's well-being in their health care seeking behaviour remains largely uncharted territory. In this study, we delve into the role of subjective well-being (SWB) in health care utilisation. We use a unique link between survey data from a representative group of Danish citizens aged 50-80 and administrative register data containing information on health care utilisation and sociodemographics. We explore whether SWB is a predictor of health care utilisation (general practice services) over and above health (as measured by health-related quality of life (HRQoL)). We find that the association between SWB and number of services provided in general practice differs across levels of HRQoL. Among those with lower HRQoL, we find a positive association between health care utilisation and SWB. Results hold true even when controlling for previous health care utilisation, suggesting that the mechanism is not driven by reverse causality. Our findings suggest that, in particular for vulnerable individuals in poor health and with poor SWB, the propensity to seek care is inappropriately low, and there is a need for more proactive supply-driven health care.

Marked by a Criminal Record? Socioeconomic Differences in the Relationship Between Early Criminal Justice Contacts and Adult Life Outcomes

AbstractThis paper combines life course theory and empirical research on the collateral consequences of punishment as a backdrop to exploring the relationship between both the presence of and seriousness of a criminal record measured in early adulthood (age 25) and later life outcomes (ages 41-49), both in total and by socioeconomic status. The analysis relies on a combination of longitudinal survey data and administrative register data for 2,022 individuals who were between 12 and 20 years old when the data collection started. Results show that the criminal record is linked to both labor market and social exclusion later in life, but most systematically to (worse) labor market outcomes. Somewhat surprisingly, low SES seems to “buffer” against some of the unwanted outcomes linked to having a more serious criminal record, while high SES seems to “boost” others. Implications for future research on both deviance and stratification are discussed.

Getting ahead in the social sciences: How parenthood and publishing contribute to gender gaps in academic career advancement.

How do parenthood and publishing contribute to gender gaps in academic career advancement? While extensive research examines the causes of gender disparities in science, technology, engineering, and mathematics (STEM) careers, we know much less about the factors that constrain women's advancement in the social sciences. Combining detailed career- and administrative register data on 976 Danish social scientists in Business and Management, Economics, Political Science, Psychology, and Sociology (5703 person-years) that obtained a PhD degree between 2000 and 2015, we estimate gender differences in attainment of senior research positions and parse out how publication outputs, parenthood and parental leave contribute to these differences. Our approach is advantageous over previous longitudinal studies in that we track the careers and publication outputs of graduates from the outset of their PhD education and match this data with time-sensitive information on each individual's publication activities and family situation. In discrete time-event history models, we observe a ∼24 per cent female disadvantage in advancement likelihoods within the first 7years after PhD graduation, with gender differences increasing over the observation period. A decomposition indicates that variations in publishing, parenthood and parental leave account for ∼ 40 per cent of the gender gap in career advancement, suggesting that other factors, including recruitment disparities, asymmetries in social capital and experiences of unequal treatment at work, may also constrain women's careers.

Acute health care use among children during the first 2.5 years of the COVID-19 pandemic in Ontario, Canada: a population-based repeated cross-sectional study.

The effects of the decline in health care use at the start of the COVID-19 pandemic on the health of children are unclear. We sought to estimate changes in rates of severe and potentially preventable health outcomes among children during the pandemic. We conducted a repeated cross-sectional study of children aged 0-17 years using linked population health administrative and disease registry data from January 2017 through August 2022 in Ontario, Canada. We compared observed rates of emergency department visits and hospital admissions during the pandemic to predicted rates based on the 3 years preceding the pandemic. We evaluated outcomes among children and neonates overall, among children with chronic health conditions and among children with specific diseases sensitive to delays in care. All acute care use for children decreased immediately at the onset of the pandemic, reaching its lowest rate in April 2020 for emergency department visits (adjusted relative rate [RR] 0.28, 95% confidence interval [CI] 0.28-0.29) and hospital admissions (adjusted RR 0.43, 95% CI 0.42-0.44). These decreases were sustained until September 2021 and May 2022, respectively. During the pandemic overall, rates of all-cause mortality, admissions for ambulatory care-sensitive conditions, newborn readmissions or emergency department visits or hospital admissions among children with chronic health conditions did not exceed predicted rates. However, after declining significantly between March and May 2020, new presentations of diabetes mellitus increased significantly during most of 2021 (peak adjusted RR 1.49, 95% CI 1.28-1.74 in July 2021) and much of 2022. Among these children, presentations for diabetic ketoacidosis were significantly higher than expected during the pandemic overall (adjusted RR 1.14, 95% CI 1.00-1.30). We observed similar time trends for new presentations of cancer, but we observed no excess presentations of severe cancer overall (adjusted RR 0.91, 95% CI 0.62-1.34). In the first 30 months of the pandemic, disruptions to care were associated with important delays in new diagnoses of diabetes but not with other acute presentations of select preventable conditions or with mortality. Mitigation strategies in future pandemics or other health system disruptions should include education campaigns around important symptoms in children that require medical attention.

Health-related exit from employment before and during the COVID-19 pandemic in Norway: Analysis of population-wide register data 2013–2021

People with health problems experience various labor market disadvantages, such as hiring discrimination and heightened risk of firing, but the impact of deteriorating economic conditions on health-related labor market mobility remains poorly understood. The strength of the downturn/crisis will most likely make a difference. During minor downturns, when few employees are made redundant, health-related exit may occur frequently since employers prefer to keep those with good health on the payroll. However, during major economic crises, when large-scale downsizing and firm closures abound, there will be less discretionary room for employers. Thus, some mechanisms that usually are damaging for people with health problems (e.g., seniority rules and negative connotations), can be neutralized, ultimately leading to smaller health differentials in labor market outcomes. The current study used population-wide administrative register data, covering the years 2013–2021, to examine health-related exit from employment (to unemployment/social assistance) before and during the COVID-19 pandemic in Norway. The pandemic spurred a major crisis on the Norwegian labor market and led to a record-high unemployment rate of 10.6 percent in March 2020. Restricting the analytical samples to labor market insiders, linear probability models showed that previous recipients of health-related benefits had a higher unemployment likelihood in the pre-crisis year 2019. The relative importance of poor health changed non-negligibly, however, during the COVID-19 pandemic. When identical statistical analyses were run on the crisis year 2020, health-related exit from employment was dampened. Yet, this labor market equalization was not followed by smaller health differentials in work income in 2021, mainly because people with good health retained or regained decent-paying jobs when the economic conditions improved again. In conclusion, major economic crises can lead to an equalization of labor market disadvantages for people with health problems, but health-related inequalities may reemerge when the economy recovers.

From unequal injuries to unequal learning? Socioeconomic gradients in childhood concussions and the impact on children's academic performance

Previous research identifies stark socioeconomic disparities in child injuries, yet research on the repercussions hereof on other aspects of children's lives remains sparse. This paper tests whether social gradients in minor traumatic brain injuries (mTBIs or concussions) contribute to corresponding inequalities in children's academic performance. Previous research on this topic is mostly based on small samples and confounded by non-random selection into experiencing mTBIs. We improve on prior research by using high quality, large N, administrative registry data. Further, we control for selection into having an mTBI via comparing the test score progression of children having an mTBI with children who experience an mTBI in later years (staggered difference-in-differences). Based on Danish ER/hospital records and national test score data, we find that children from families with lower earnings and less education are more likely to experience an mTBI and that having an mTBI negatively correlates with reading test scores. However, comparing present with future mTBI cases, we show that having an mTBI within a year before a test does not negatively affect children's reading scores. Our findings suggest that negative correlations between mTBIs and academic performance more likely reflect socioeconomic gradients in mTBI incidents rather than a direct causal effect. Further, socioeconomic gradients in mTBI incidents do not significantly contribute to corresponding disparities in academic performance.

Machine learning estimation of the resident population

In this paper, we formulate the problem of estimating the resident population, i.e. correcting for over-counts in administrative register data, as a binary classification problem. We propose a solution based on machine learning algorithms. The selection and the optimisation of the best algorithm is shown to depend on the goal of prediction. We illustrate this method for two important cases of official statistics, Census resident population and survey design with minimum non-response. The performance of the algorithms, the uncertainty of estimates and of the evaluation metrics are described in detail and implemented in shared, open source code. We exemplify with the results obtained by applying this method to Icelandic register and survey data.

Nation-builders and market architects: How social origins mold the careers of law graduates over 200years in Norway.

This paper examines the types of work that jurists have historically undertaken and maps how opportunities for legal practice have been shaped by social origins across three centuries: after constitutional independence in the mid-1800s, during industrial capitalism in the mid-1900s, and at present-day advanced capitalism. I analyze historical archive data on law graduates from the 19th and 20th centuries in combination with administrative registry data from the 1990s onwards and employ correspondence analysis to explore how social backgrounds shape careers, considering transformations in class structures and the changing significance of juridical expertise over time. Within each period, jurists have served in very different roles including those that craft and cater to the institutional make-up of the state and the markets. My analysis shows that the impact of social origin on occupational outcomes has undergone significant changes, mirroring shifts in the broader social structure; from the importance of legal and political capital (within regional jurisdictions) in the 19th century to the significance of economic capital as the main structuring principle, but also a greater significance of cultural capital, in contemporary times. The ability to reach the most powerful positions among law graduates-within the polity in the 19th century, and the economy in the 21st century-has been differently structured by origins. I argue that expansion of the student body, the declining standing of the university, and heightened differentiation of the social structure and the juridical field have made intimate familiarity with the business world pivotal for forging mutually beneficial alliances between jurists and the increasingly dominant capitalist class. Today, a select group of jurists have managed to connect with and contribute to the rising power of private capital. Thus, the historical tale of jurists cannot be accurately captured by notions of uniform descent from national power structures.

Parental job loss and the role of unemployment duration and income changes for children’s education

Abstract This article studies the impact of parental job loss, subsequent unemployment duration, and income changes on the results of the final exam in lower secondary education and on the decision to pursue an academic track in Denmark. Drawing on administrative register data we use sibling fixed effects models as well as a before-after-test design to investigate the shorter-term effects of parental job loss. The results show that there are hardly any effects of parental job losses on children’s exam results, while we find a reduction in the transition to the academic upper secondary track, both for maternal and paternal job losses. We find no systematic evidence that the negative effects would be larger if the job loss is followed by a longer period of unemployment or by a loss of income, and no evidence for a moderating role of parental education.

Identifying user profiles of healthcare, social and employment services in a working-age population: A cluster analysis with linked individual-level register data from Finland.

A thorough understanding of the use of services in the population is important in order to comprehend the varying service needs of different groups. This explorative study aimed to find distinct user profiles in a working-age population based on individuals' annual use of healthcare, social and employment services and to explore socio-demographic and morbidity-related predictors of the user groups. Administrative register data on the use of various services and individual-level covariates from year 2018 were linked for all residents aged 18-64 of the municipality of Oulu, Finland (N = 119,740). K-means cluster analysis was used to group the study subjects into clusters, based on their frequency of using 22 distinct healthcare, social and employment services during 2018. Multinomial logistic regression models were utilized to assess the associations of cluster assignment with socio-demographic and health-related covariates (sex, age, marital status, education, occupational class, income, days in employment, chronic disease and receipt of different social benefits). Five distinct clusters were identified in terms of service use, labelled low to moderate users of healthcare (82.0%), regular employment services users with moderate use of healthcare (9.6%), supported employment services users with moderate use of healthcare with an emphasis on preventive care (2.9%), frequent users of healthcare, social and employment services (2.9%), and rehabilitation, disability services and specialized healthcare users (2.6%). Each cluster not only showed different patterns of service use but were also differently associated with demographic, socio-economic and morbidity-related covariates, creating distinct service user types. Knowledge on the different user profiles and their determinants may help predict future need and use of services in a population, plan timely, coordinated and integrated services, and design early interventions and prevention measures. This is important in order to save costs and improve the effectiveness of services for groups with different care needs.

Sibling complexity and psychiatric disorders in late adolescence among the Finnish 2000 birth cohort

Abstract Background Due to the increasing family instability and multipartner fertility in Western countries, more children have half- and stepsiblings. While numerous studies link family instability and complexity with mental health problems, the focus has typically been on the parents while a small but growing literature suggest that sibling constellations with half- and stepsiblings may also be important for adolescent mental health. Methods This study is based on administrative register data of all children born in Finland in 2000 and residing there at ages 0 − 15 (n = 56,372). We identified the biological parents, their cohabiting partners, and any full, half and step siblings that the index child has from birth to age 15. We used Cox proportional-hazards models to compare differences in psychiatric disorders from age 16 to 19 for boys and girls by different sibling constellations. Psychiatric disorders were identified as any disorders treated in specialized outpatient or hospital care (n = 7,999). Results Almost one in five children in the birth cohort had a cohabiting half sibling and almost 4% had a step sibling. Psychiatric disorders in late adolescence were more prevalent among children in different sibling compositions with half or step siblings. For example, the preliminary results show that adjusting for confounders such as socioeconomic status and living with both biological parents or not, boys and girls with an older half sibling had a 44% (95% confidence interval 34-55) higher risk of psychiatric disorders when compared to children with biological siblings only. The corresponding difference in risk for those with younger half siblings was 24% (11-55). Conclusions Psychiatric disorders were more prevalent in late adolescence among children with half and/or step siblings. Future studies on family complexity are likely to benefit from including information on sibling characteristics in addition to those of the parents. Key messages • Adolescents growing up with half or stepsiblings had a higher prevalence of psychiatric disorders in late adolescence. • More studies on sibling composition and adolescent psychiatric disorders are needed to inform the type of supportive measures that may benefit children living with half and stepsiblings.

Correlation between cognitive ability and educational attainment weakens over birth cohorts

Educational attainment is a key indicator of status and opportunity in meritocratic societies. However, it is unclear how educational expansion has affected the link between cognitive abilities and educational attainment. As a result, this study examines the correlation between cognitive ability and educational attainment across male birth cohorts in Norway. Utilizing administrative register data covering more than four decades, we investigate multiple measures of educational attainment and their connection to cognitive abilities. Our findings reveal a consistent decline in the correlation over time. These findings question the assumed shift towards meritocracy in educational systems and highlight a more complex relationship between cognitive ability and educational attainment.

The Swedish Kinship Universe: A Demographic Account of the Number of Children, Parents, Siblings, Grandchildren, Grandparents, Aunts/Uncles, Nieces/Nephews, and Cousins Using National Population Registers

Given that surprisingly little is known about the demography of human kinship, we provide a demographic account of the kinship networks of individuals in Sweden in 2017 across sex and cohort between ages 0 and 102. We used administrative register data of the full population of Sweden to provide the first kinship enumeration for a complete population based on empirical data. We created ego-focused kinship networks of children, parents, siblings, grandchildren, grandparents, aunts and uncles, nieces and nephews, and cousins. We show the average number of kin of different types, the distribution of the number of kin, and changes in dispersion over time. A large share of all kin of an individual are horizontal kin, such as cousins. We observe the highest number of kin—on average, roughly 20—around age 35. We show differences between matrilineal and patrilineal kin and differences in the kinship structure arising from fertility with more than one childbearing partner, such as half-siblings. The results demonstrate substantial variability in kinship within a population. We discuss our findings in the context of other methods to estimate kinship.
