Output of a group-based trajectory model. Panel A presents the yearly median values for the trajectories of exposure to affluence in the neighborhood, school, and workplace, broken down by the trajectory groups. Panel B displays the distribution for each of the GBTM
groups by the 1990 household income percentile.

Panel A presents the yearly median values for the trajectories of exposure to affluence in the neighborhood, school, and workplace, broken down by the trajectory groups. Panel B displays the distribution for each of the GBTM groups by the 1990 household income percentile.

While social exposure clearly follows a socioeconomic gradient, our trajectory clustering reveals that 17% of low-income origin individuals are highly exposed to affluence and show better outcomes than their lower-exposed peers (/!\ this is purely associational). (4/5)

Trajectories of exposure to affluence (top, Panel A) and poverty (bottom, Panel B) in the neighborhood, school, and workplace. The trajectories show the median value for a given year, broken down by the household income quintile in 1990 (yellow is first quintile, purple is last quintile) when the cohort was aged around 16.

Second, social exposure follows a clear U-shape over time, with initial increase in poverty exposure after leaving home followed by a convergence back to origin levels (with opposite trends for affluence, ↘️ then ↗️), especially among high-income individuals. (3/5)

Measures of cross-domain correlation for exposure to affluence for individuals registers in multiple domains in a given year. Levels of exposure to affluence are correlated across all life domains. 
Notation: Work = Workplace; Uni. = University; Upp. = Upper secondary school; Comp. = Compulsory school; Nbhd. = Neighborhood

Notation: Work = Workplace; Uni. = University; Upp. = Upper secondary school; Comp. = Compulsory school; Nbhd. = Neighborhood

We measure social exposure as the share of top- and bottom-income individuals in each domain at the individual level.

First, we find high levels of socioeconomic homogeneity across life domains, with strong cross-domain correlations at each point in time and over individuals' life course. (2/5)

Most segregation research examines neighborhoods, schools, or workplaces separately. But do individuals' exposure align across domains and persist over the life course? We fill this gap using 27 years of 🇸🇪 data.

📢 In this Social Forces article, I introduce occupational elitism as a novel measure of social closure: the share of upper-class background workers within an occupation.

Its consequences for earnings stratification can be examined using a social closure theory lens.

Parental education is still key, but proximity reduces the gap a little: kids from less educated families gain most from living close to a university.

👉 Bottom line: geography shapes aspirations and can reinforce inequality.

Excited to share this first article from my PhD 🎉

Why? Distance effects are often explained by exposure to the academic environment and by the costs of distance. We find that peer exposure explains part of the effect—but not all. Even after accounting for it, distance still matters, with costs reducing aspirations as early as age 15.

Line chart showing the probability of applying to an academic track by distance to the closest higher education institution (HEI) in kilometers. The baseline model (red line with squares) shows a sharp decline in probability from about 0.72 near universities to around 0.61 at 100 km, with the steepest drop between 5 and 20 km. When accounting for academic exposure (blue line with circles), the probability is consistently lower and flatter, around 0.65, with only a slight downward trend across distance. Shaded areas show confidence intervals.

Shaded areas show confidence intervals.

The effect is big: students furthest from a university are up to 12 percentage points less likely to apply for the academic track.

The effect is strongest between 5–20 km: even small differences in distance here can make a big impact. Beyond ~20 km, the effect levels off.

Together with Maria Brandén and Erik Rosenqvist, we show that distance to higher education shapes academic aspirations in Sweden—well before their university education begins. (1/4)
