Planet Money: "Can transforming neighborhoods help kids escape poverty?"

Host: NPR
Date: January 28, 2026

Episode Overview

This episode investigates whether transforming impoverished neighborhoods can provide a pathway out of poverty for low-income children. NPR’s Keith Romer and Greg Rosalski explore the federal Hope VI (Hope 6) program, which rebuilt public housing projects around the country, and discuss new research led by Harvard economist Raj Chetty. The episode interrogates whether revitalized, mixed-income neighborhoods help lift children out of poverty—and if so, why.

Key Discussion Points & Insights

1. The Hope VI Program: Background and Legacy

• Personal Narrative Start [00:43]: Ysena Williams recounts witnessing the demolition of Cambridge Plaza, a public housing tower in North Philadelphia.
• Lived Experience: Ysena describes her childhood in Richard Allen Homes as "depressing," unsafe, and plagued by environmental hazards such as lead paint.
  ↳ “So we had lead, the paint was chipping… it just wasn’t bright. It wasn’t happy.” – Ysena Williams [02:25]
• Hope VI’s Purpose [01:29]: Initiated in the early 1990s, Hope VI sought to demolish and rebuild some of the nation’s worst public housing, creating mixed-income, safer, and better-integrated neighborhoods.

2. The “Neighborhood Experiment” [03:24–04:15]

• A Natural Experiment: Not enough funding for every project led to some old projects remaining and others being transformed, creating a large-scale, unintentional experiment in neighborhood effects.
• Crucial Question Raised: Can investing in neighborhoods and making them economically mixed actually help kids escape poverty?
• Study Introduction: Harvard economist Raj Chetty and his team gathered data on over a million families in public housing from the past three decades.

3. Raj Chetty’s Study & Findings [04:15–13:24]

• Key Paper: "Creating High Opportunity Neighborhoods: Evidence from the Hope 6 Program" – Raj Chetty [04:20]
  • Chetty describes the evidence as “very compelling.” [04:37]
• Data Access: More than a million families tracked over decades, assessing outcomes for adults and their children.
• Main Results [12:27]:
  • While adults saw little change, children benefited substantially from growing up in a revitalized, mixed-income Hope VI neighborhood.
  • “You ended up earning about 50% more if you grew up from birth in one of these places… than if you’d grown up in the exact same place pre-revitalization.” – Raj Chetty [12:56]
  • Other positive effects: higher college attendance, lower incarceration rates for boys.

4. Addressing Selection Bias and Causality [14:08–17:46]

• Potential Issues:
  • Critics suggest selection bias: were “revitalized” Hope VI residents systematically different (more motivated, etc.)?
• Methodology:
  • Used “dosage effect”: The longer a child spent in Hope VI, the higher their adult income. Each year in Hope VI increased adult earnings by ~3%. [16:18]
  • Sibling Comparison: Compared siblings who lived different durations in Hope VI—those who arrived younger fared best.
    ↳ “The younger sibling should earn more later in life compared to their older sibling… That’s exactly what we find in the data.” – Matt Stager [17:09]

5. The Mechanisms: Why Do Mixed-Income Neighborhoods Work? [17:48–22:35]

• Not All Hope VI Sites Worked: Kids only benefited if the development was near more affluent neighborhoods.
  • “If surrounding neighborhoods were poor…Kids in Hope 6 development saw no gains.” – Greg Rosalski [19:17]
• Social Integration is Key:
  • Evidence showed Hope VI kids were more likely to connect with higher-income peers on social media and in adulthood.
  • “It’s not the architecture…it’s like who you’re interacting with.” – Keith Romer [20:24]
• Why Do Connections Matter? Raj Chetty outlines three possible mechanisms:
  1. Job Networks: “If you’re connected to somebody who’s got a good job…you’re more likely to get that job.” – Raj Chetty [21:20]
  2. Information/Exposure: “If you live near somebody whose parents went to college, you might be more likely to think about applying…” [21:41]
  3. Aspirations (Most compelling to Chetty): “People’s aspirations…are greatly shaped by who they’re around.” [22:00]

6. Limitations and Policy Implications [25:13–27:55]

• Hope VI’s Controversial Legacy:
  • The program ended over a decade ago and drew criticism for destroying more units than it rebuilt—displacing many families.
  • “Our analysis definitely does not…endorse Hope 6 as a program. I think concerns around displacement should be taken very seriously.” – Matt Stager [26:01]
• Scalability & Next Steps:
  • Economic segregation is growing. Over half of low-income neighborhoods remain as isolated as the old pre-Hope VI projects.
  • “We could be spending the $70 billion a year on affordable housing programs more effectively.” – Raj Chetty [27:20]
  • Broader relevance: Schools, sports, and mass transit can also foster the crucial higher-income/low-income connections identified.

7. Voices from the Neighborhood: Ysena’s Perspective [28:03–29:59]

• Ysena’s Son: Grew up in a revitalized Hope VI development; attended Penn State, pursued trade school, and now has a steady job and future prospects.
• Neighborhood Impact:
  ↳ “Well yes, they will [succeed] because…you’re coming from a mentality where you’re caged in, where now you’re not. So, yes, I do agree, yes, they will make more. They will succeed. Yes.” – Ysena Williams [29:45]

Notable Quotes & Moments

• “If you have more high income connections as you’re growing up…you yourself are more likely to rise out of poverty.”
  – Raj Chetty [07:57]
• “You can’t move everyone to a different neighborhood.”
  – Raj Chetty [08:34]
• “It’s not the architecture per se that generated these gains.”
  – Matt Stager [20:29]
• “People’s aspirations and what they try to achieve…are greatly shaped by who they’re around.”
  – Raj Chetty [22:00]
• “Concerns around displacement should be taken very seriously.”
  – Matt Stager [26:01]
• Personal Touch: Referring to Raj Chetty as “the Beyoncé of economics.” – Greg Rosalski [07:06]

Conclusion

Planet Money’s episode provides compelling evidence that transforming poor neighborhoods into mixed-income communities can substantially improve life outcomes for children, but the benefits crucially depend on true economic integration and social connectivity. The findings suggest that policy makers should focus on reducing economic segregation and fostering meaningful, cross-class interactions—whether through housing, schools, or other avenues—while remaining mindful of the risks of displacement and exclusion in revitalization efforts.
