Moving to the American dream? (update)

Episode Summary

Executive Summary: The episode revisits the Moving to Opportunity housing experiment, which initially seemed to show housing vouchers had no effect on income or education. New IRS tax-data analysis by Raj Chetty and Nathan Hendren later revealed a crucial hidden effect: moving young children to lower-poverty neighborhoods boosted adult earnings and mobility, while neighborhood opportunity is strongly shaped by social capital and local employment. Their latest research shows opportunity can rise or fall over time within places.

Main Topics: The original Moving to Opportunity housing experiment (Priority: 5/5): HUD randomized families into public housing, regular vouchers, or vouchers requiring moves to low-poverty neighborhoods to test whether changing neighborhoods could improve long-term outcomes. Initial findings: housing seemed not to change life outcomes (Priority: 5/5): After years of tracking families, the original report found no effect on children’s test scores, adult earnings, education, or income, leading many to conclude housing was not a path to mobility. Reanalysis with IRS tax data revealed age-dependent effects (Priority: 5/5): Raj Chetty and Nathan Hendren used larger tax records to show that moving to higher-opportunity neighborhoods improved outcomes for children under 13, explaining why the original study missed the effect. What makes a neighborhood high-opportunity (Priority: 5/5): The research shifted from housing itself to neighborhood social capital—especially interaction between low- and high-income residents—and the share of adults who are working. Rebooting mobility policy with support services (Priority: 4/5): A newer version of the program removed forced relocation and instead used housing counselors and assistance to help families voluntarily move to high-opportunity areas, significantly increasing take-up. Changing opportunity over time across groups and places (Priority: 4/5): Chetty’s latest paper finds mobility has changed unevenly: some poor Black communities improved while poor white communities worsened, with local employment rates strongly predicting the shift.

Key Arguments: The first HUD experiment failed to detect mobility gains because it measured outcomes too early; the benefits appeared later when children reached adulthood. Neighborhoods matter for long-term economic mobility, but the mechanism is not simply housing quality; social connections and access to working adults are major drivers. The impact of moving depends heavily on age: younger children benefit, while moves after age 13 can be slightly harmful. Policy works better when it reduces barriers rather than forcing choices; housing counselors and deposit help can materially increase successful moves. Opportunity is not fixed geographically; communities can become more or less upwardly mobile over time, suggesting policy can shape local economic trajectories.

Data Points: Families in original experiment: about 4,600 families - Participants across five cities in HUD’s Moving to Opportunity study Cities in original experiment: 5 - Baltimore, Boston, Chicago, Los Angeles, and New York Neighborhood poverty threshold for experimental vouchers: 10% or less poor neighbors - Families in the special voucher group had to move to low-poverty neighborhoods Typical poverty rate in families’ original neighborhoods: about 50% - Context for the relocation target in the experiment Year moving began: 1994 - Start of the randomized relocation experiment Data collection completion: 2008 - Original MTO data gathering finished before the later reanalysis Age cutoff for benefits: under 13 years old - Only children who moved before age 13 showed positive long-term effects Income effect for younger children: about 30% more earnings - Long-term adult earnings gain for children moved when young College effect: 4 percentage points more likely to go to college - Benefit associated with moving young children Teen pregnancy: less likely - Observed among children who moved at younger ages Supportive move success in Seattle: more than half - Families using vouchers in high-opportunity neighborhoods after receiving counselor support Increase in high-opportunity moves with counseling: more than 3x - Compared with families who received vouchers without support Study population in Chetty's new paper: 57 million people - People born between the late 1970s and early 1990s Black-white gap in economic mobility: fallen by one-third - Driven partly by improvements in some low-income Black communities and declines among poor white communities European comparison: twice as likely - Data point noting Americans at the bottom are about twice as likely to achieve the American dream in Europe

Pivotal Quotes: "Housing is just housing." — HUD researchers / original MTO interpretation: The original conclusion after the first wave of data suggested housing policy alone did not improve income, education, or employment "The answer to that question was no." — Narrator summarizing original MTO findings: Refers to whether changing a family’s address could change the course of economic life "Where you grow up plays an enormous role in shaping your long-term outcomes." — Raj Chetty: Summarizing the core finding of Opportunity Insights research on neighborhood effects

Implications: Neighborhood policy can meaningfully improve mobility, but effects are strongest for young children and depend on social connection and local employment. Future policy may focus less on forcing moves and more on removing barriers and strengthening opportunity within places.
