How well can we predict which children will end up poor adults or rich adults? Or how much education they'll earn? In a new working paper, @zparolin.bsky.social and I show the predictability of life outcomes depends on the country and outcome.

www.inet.ox.ac.uk/publications...

Highlights below! 🧵👇
Title: Rags or Riches? Predicting Life Outcomes from the Birth Lottery Across Five High-Income Countries Authors: Orestes P. Hastings and Zach Parolin Abstract: The stratification of life outcomes is a central concern of sociology, but to what extent can adult outcomes be predicted from childhood circumstances? Although decades of research have identified important family and socioeconomic factors associated with mobility and attainment, these models explain only a modest share of individual variation in outcomes. Using harmonized longitudinal data from the Cross-National Equivalent Files (CNEF) and an ensemble of machine-learning models, we estimate the predictability of adult outcomes in the United States, United Kingdom, Germany, Australia, and South Korea. Predictability varies substantially across outcomes and national contexts: educational attainment is more predictable than economic outcomes, poverty is far more predictable in the U.S., and income mobility is substantially less predictable than overall attainment outcomes. Additional U.S. analyses show that adding race, wealth, parental incarceration, and other variables improves predictions only slightly. We further show that predictability captures a distinct dimension of stratification not fully captured in other traditional measures of mobility, inequality, and opportunity. Together, these findings provide new insights into where and how the birth lottery most strongly shapes life chances.

new paper: we update risk estimates for child welfare system outcomes (investigation, confirmed, foster care, termination of rights) by race/ethnicity using 2016-2023 data. Black and AIAN kids still most likely to have system contact, but rates are down across the board compared to mid 2010s
A two panel plot showing estimates of lifetime risks of investigation and confirmed maltreatment for seven racial and ethnic groups. There is a slight downward trend over time A two panel plot showing risk estimates for foster care and termination of parental rights. Foster care rates have a noticeable downward slope. Termination rates have a smaller negative change over time.

New in @sfjournal.bsky.social, just in time for summer reading 📚☀️ Cohesive schools are widely thought to curb youth offending, but the evidence is quite mixed. I find that popular boys in such schools may experience more leeway to offend—what I call a "code of cohesion." doi.org/10.1093/sf/s...

Happy to share our new paper published in PNAS!

Using epigenetic clocks and egocentric network data, we find each additional "hassler" in your close social network is associated with ~9 months of extra biological age and 1.5% faster pace of aging.
