Swedish study finds school breaks cut youth assault by nearly half
A new analysis of Sweden's staggered winter school holidays reveals that time away from school reduces violent assaults among children aged 7–14 by 46 percent, suggesting the school environment itself concentrates youth conflict. The finding has implications for how policymakers design school schedules and how businesses plan workforce demands around holiday periods.
Originaltitel: School Breaks and Crime: Quasi-Experimental Evidence from Sweden
<p>Objectives: We estimate the causal effect of school holidays on crime by exploiting thestaggered timing of the Swedish winter sports break (sportlov) across municipalities.Methods: We use a difference-in-differences design with municipality and year-by-weekfixed effects on panel data covering 290 municipalities over 208 weeks (2021–2024). Poisson pseudo-maximum-likelihood (PPML) is the primary specification, with county-levelcluster inference and Romano-Wolf step-down adjusted p-values for family-wise correction.Results: The break reduces recorded assault by about 13 percent (PPML), concentratedamong children of compulsory-school age (7–14: −46%; 15–17: −32%), with no effecton placebo groups (ages 0–6 or adults). Residential burglary increases by about 14 percent, consistent with empty homes during family travel, while crime rises at ski-destinationmunicipalities during the sportlov season, consistent with tourism-driven inflows. Eventstudy estimates show no pre-trends and no intertemporal displacement. Aggregate totalcrime and property-crime estimates point in the same direction but are smaller and notrobust to family-wise correction.Conclusions: The school environment concentrates youth in ways that produce interpersonal-conflict opportunities; the break disperses that concentration for one week andassault drops. Aggregate effects on total and property crime are suggestive but sensitive tospecification.</p>
