Economic outcomes
Recent work consistently shows that states/regions with faster growth in college-educated shares (bachelor’s or higher among adults 25+) experience stronger income growth, GDP gains, innovation, and reduced inequality—while “brain drain” areas lag. Key mechanisms include higher local productivity, attraction of high-skill jobs, and spillovers to non-college workers.
- A 2023 Urban Institute analysis of state economic performance since 1970 finds that educational attainment is the single strongest predictor of long-run median income growth. States with larger gains in college shares saw the biggest inflation-adjusted income increases; the authors note this reflects both direct effects (higher-earning residents) and indirect ones (job markets pulling in more educated migrants).
- Analyses of long-run regional inequalities (e.g., 2021 work on U.S. economic development) highlight that human capital divergence—now tied to tech/service sectors rather than manufacturing—explains much of the gap in per capita income across states. College attainment shares vary dramatically (e.g., >20% in New England vs. ~10% in parts of Appalachia), driving persistent divides in growth.
- Brain-drain/gain studies quantify costs and benefits: A 2025 Common Sense Institute report on Iowa estimated a $96 billion cumulative earnings loss from out-migration of public university graduates over two decades, with ripple effects on state GDP (potentially $7 billion higher annually with better retention). Similar dynamics appear in broader JEC and Upjohn Institute work on skilled migration.
Health outcomes
Divergence in college attainment has also widened geographic and individual health gaps, especially via mortality, life expectancy, and behaviors (smoking, obesity). College-educated populations create positive spillovers for entire communities.
- NBER working paper (2024) by Bor et al. (“Human Capital Spillovers and Health”) finds that every 10 percentage-point increase in an area’s share of college-educated adults is associated with a 7% decline in all-cause mortality, even after controlling for individual education. The effect has strengthened since 1990, driven by lower smoking and obesity rates in high-attainment areas (via norms, information, and healthier environments). Spatial sorting of sicker people does not explain this—it's genuine spillover.
- Updates to Case-Deaton research (2024 paper on education, health-based selection, and the widening mortality gap) document that the life expectancy gap between those with vs. without a college degree grew from ~2.6 years (1992) to 6–8+ years by the early 2020s. This divergence interacts with geography: Non-college mortality has stagnated or risen in lower-attainment regions, while college graduates see steady gains almost everywhere.
- Related 2026 NBER digest work on midlife mortality shows geographic divergence in death rates (rural vs. urban, by education) is largely explained by smoking patterns, which track college attainment levels. College-heavy areas have converged on low mortality; non-college areas have diverged sharply.
Broader reviews (e.g., 2024 Annual Review of Sociology on widening educational disparities in health/longevity) confirm these patterns hold across causes of death and have accelerated in recent decades.
Overall takeaways and links to state divergence
These papers emphasize feedback loops: Migration-driven brain gain raises local college shares → better economic opportunities + healthier behaviors → further attraction of talent (and better outcomes for everyone). Conversely, brain-drain states see slower economic growth and worsening relative health, compounding inequality.
