The relationship between inequality and social mobility has been studied primarily through the lens of income. The "Great Gatsby Curve"โ€”the empirical regularity that countries with higher income inequality tend to have lower intergenerational income mobilityโ€”is among the most cited findings in economics. But income is only part of the picture. Wealthโ€”encompassing housing, financial assets, business equity, and inheritancesโ€”is distributed far more unequally than income and may exert a stronger influence on whether children can surpass their parents' economic position. Recent research, enabled by newly available wealth data, is beginning to fill this gap.

The Research Landscape

Wealth Inequality and Upward Mobility in the United States

Schechtl (2025), publishing in Nature Communications, provides the most direct evidence on the wealth-mobility link. Using the GEOWEALTH-US databaseโ€”a recently published dataset of local wealth inequality estimates covering U.S. commuting zonesโ€”combined with upward mobility estimates from the Opportunity Insights project, the study examines whether childhood exposure to local wealth inequality is associated with later-life income mobility.

The findings are clear: local wealth inequality is negatively associated with upward income mobility. Children who grow up in commuting zones with higher wealth inequality are less likely to move up the income distribution as adults. Crucially, the study's static simulations show that wealth inequality has a stronger association with upward mobility than income inequality itselfโ€”suggesting that the Great Gatsby Curve may understate the relationship between inequality and immobility by focusing on income alone.

One proposed mechanism is educational: higher local wealth inequality is associated with lower educational attainment among children from low-income families. Wealthy communities may invest in high-quality schools and enrichment activities that are spatially concentrated, creating opportunity structures that are physically proximate but socially inaccessible.

The Geographic Dimension

Connor, Xie, and Jang (2025), publishing in PNAS Nexus examine how urbanization interacts with inequality and mobility. Their analysis addresses a longstanding tension: cities are engines of economic dynamism and wealth creation, but they are also sites of concentrated inequality and social stratification. The study finds that big cities fuel inequality both within and across generationsโ€”urban wealth premiums are substantial but accrue primarily to those who already own property, while urban wage premiums have diminished for low-skill workers.

This creates a geographic trap: the places with the most economic opportunity are also the places where the cost of entry (housing, education, social networks) is highest, and where inequality makes the rungs of the social ladder furthest apart.

Cross-National Evidence on Wealth Transmission

Dewilde (2024) examines the intergenerational transmission of financial disadvantage across European countries. The study finds that rising poverty risks among working-age households have consequences that extend into retirement, creating intergenerational chains of financial vulnerability. Notably, the transmission mechanisms differ across welfare state types: in liberal welfare states (UK, Ireland), asset poverty is transmitted primarily through low homeownership rates; in continental welfare states (Germany, France), occupational pension gaps play a larger role.

Wealth and Income Stratification by Class

Gil-Hernรกndez, Salas-Rojo, and Vidal (2025) analyze wealth and income stratification across five European countries, finding that social class differences in wealth are substantially larger than social class differences in income. The wealth gap between the professional-managerial class and the working class is approximately 3โ€“5 times the income gap, depending on the country. This matters because wealth provides security, opportunity, and intergenerational advantage in ways that income alone does notโ€”it funds education, buffers against unemployment, enables homeownership, and can be directly transferred to the next generation.

The GEOWEALTH-US Database

Suss, Kemeny, and Connor (2024) describe the construction of GEOWEALTH-US, the first subnational wealth inequality dataset for the United States covering 1960โ€“2020. The data reveal that spatial wealth inequality has increased substantially since the 1980s, with coastal metropolitan areas pulling away from the interior. This dataset enables the kind of analysis Schechtl (2025) conductsโ€”and its creation represents a methodological advance that should generate further research.

Open Questions

  • Policy implications: Should policy focus shift from income redistribution (progressive taxes, transfers) to wealth redistribution (inheritance taxes, baby bonds, universal asset-building programs)?
  • Housing as the key mechanism: Given that housing is the largest wealth component for most families, are housing policies the most effective lever for reducing wealth-based mobility barriers?
  • Racial wealth gaps: The racial wealth gap in the U.S. is substantially larger than the racial income gap. How does this interact with the geographic patterns identified by Schechtl and Connor et al.?
  • Measurement: Wealth is harder to measure than income. How sensitive are the findings to measurement approaches?
  • Where This Stands

    The emerging wealth-mobility literature suggests that decades of mobility research focused on income may have been looking at the smaller part of the problem. Wealth inequalityโ€”more extreme, more persistent, and more directly transmissible than income inequalityโ€”appears to be a stronger determinant of whether children can exceed their parents' economic position. The policy implications are substantial but politically challenging: interventions in wealth distribution touch property rights, inheritance norms, and housing markets in ways that income redistribution does not.
