📄 New paper in PNAS! Using data from ~40,000 Norwegian trios, we extend evocative gene–environment correlation to family demography. Accounting for parental PGIs, most traits showed no associations, but children's ADHD PGI predicted parental separation. www.pnas.org/doi/10.1073/...

Did the iPhone *really* cause the baby bust? A more skeptical reading of the new viral study from LCDS Deputy Director @drjenndowd.bsky.social jenndowd.substack.com/p/did-the-ip...? #demography #econsky #causalsky @nuffieldcollege.bsky.social @oxpop.bsky.social

Did the iPhone Cause the Baby Bust?

I'm not so convinced. An interesting new paper highlights the power and pitfalls of simple stories

What’s happened to income-group gaps in parental spending on children in the U.S.? For the last 45 years, they just. keep. getting. wider. In a new @socarxiv.bsky.social working paper, I present updated evidence on trends in spending on childcare, education, and extracurricular activities.

A new Annual Review article by @arnoutvanderijt.bsky.social and colleagues worth a read. Don't let the formal modeling of luck fool you. This is one of the more interesting, and all around crazier, articles I've read recently. Super cool. www.annualreviews.org/content/jour...

Luck and Predictability in the Life Course

There is an emerging recognition among sociological theorists that luck may play a substantial role in life course achievement. There is also a nascent empirical literature that finds life outcomes to...

New paper, open access in EJP We link the Danish GGS to administrative records and find recall error in cohabitation histories grows ~0.5–0.6pp/year — ~12pp over 20 years. We also show how to correct it with regression calibration using a small validation subset. link.springer.com/article/10.1...

🚨I’m Hiring!: Postdoc in Social Epidemiology (REMOTE) I'm seeking to hire a postdoc with research interests in the social determinants of health with a focus on dementia and methods to strengthen causal inference. This is a great opportunity to contribute to research to inform public health policy.

Very happy about this publication. We managed to pool two unique data sources: Behavioral reading data from the reading app Bookbites (used in many schools in DK) and population level data on library-loans. Both sources of data confirmed the same trend regarding gender differences in reading.

Ea Blaabæk@blaabaek.bsky.social · 4mo ago

When schools close, due to COVID-19 lockdown or holidays, the gender gap in reading increases. This is a challenge as boys already struggle more with reading skills than girls. New paper in @pnas.org with Emil Smith, @davidreimer.bsky.social & @madsjaeger.bsky.social www.pnas.org/doi/10.1073/...

Can a digital intervention buffer the long-term health costs of divorce? In our new JMIR paper, we link an RCT of 1,856 Danish divorcees to national registers over 5 years. Result: 28% fewer filled psych prescriptions + delayed reductions in GP visits and hospitalizations. jmir.org/2025/1/e69387

Digital Health Intervention for and Long-Term Health Outcomes of a Divorce Cohort With Linked Danish Data: 5-Year Posttrial Follow-Up of a Randomized Controlled Trial

Background: Digital health interventions are increasingly promoted as scalable and cost-effective approaches to support mental health and resilience. Short-term benefits are well documented, but evide...

JOB! I'm hiring a postdoc for 2 years on my ERC MaMo project. Looking for someone with strong quant methods, ongoing work close to the project's aims, and a desire to publish in sociology. Start flexible in the next 12 months. Formal call out shortly, but contact me first.

Markets and Mobility: How Employers Structure Economic OpportunityIntergenerational mobility, measuring the ability to achieve economic success regardless of family background, is a critical reflection of a society’s commitment to equality of opportunity. Rising income inequality has raised concerns about the potential erosion of upward mobility. While education has traditionally been viewed as the path to mobility, its transformative power is facing challenges in a rapidly evolving job market. This project reorients the focus of intergenerational mobility research by highlighting the labor market as an arena for the reproduction of advantage. It employs a comparative approach, using administrative data from four countries: Sweden, Austria, England, and the United States. It also incorporates evidence from a broader set of nations through cross-national surveys, longitudinal household surveys, labor force surveys, secondary data, and digital trace data. The project employs cutting-edge empirical methods, including quasi- experimental designs, event studies, within-family comparisons, decomposition analyses, counterfactual simulations, and diagnostic checks to rigorously assess the extent of inequalities in the labor market. The research investigates how family background influences the sorting of individuals to employers and workplaces, accounting for education and occupation, and explores variations in career progression within and between employers. It comprehensively catalogues and assesses mechanisms shaping workplace inequality, contributing to the development of social closure theory. Additionally, the project evaluates intervention strategies, encompassing both employer practices and government actions, to promote fair opportunity in the labor market.

New paper finally published! Using data on 78 million births from 15 countries, we found that babies conceived during the COVID-19 pandemic have a different parental socioeconomic composition than expected had the pandemic not occurred. doi.org/10.1038/s414... @natcomms.nature.com @helsinki.fi

Screenshot of the title and abstract: Parental socioeconomic composition of birth cohorts changed during the COVID-19 pandemic. The COVID-19 pandemic offers opportunities to study effects of in-utero and early life exposure to environmental changes. However, inferences from such studies may be flawed if the pandemic has changed the socioeconomic composition of parents. Analysing over 77.9 million live births from 15 countries, we estimate changes in the socioeconomic composition of the cohort born between December 2020 and December 2021 using interrupted time series analysis. We find that, compared with their counterfactual compositions, the December 2020-December 2021 birth cohort has a higher proportion of babies born to socioeconomically advantaged parents in Austria, England, Finland, the Netherlands, Scotland, Spain, Wales, and the United States while we observe the opposite change for Brazil, Colombia, Ecuador, and Mexico. These changes in cohort composition may cause between-cohort differences in life course outcomes that are influenced by parental socioeconomic circumstances even if early life exposure to the pandemic had no direct effect on this birth cohort.
