Episode: The link between immigration and longer life
Host: David Brancaccio
Guest: Brian McGarry, Faculty Research Fellow at the National Bureau of Economic Research
Air date: February 24, 2026

Episode Overview

This episode centers on new economic research revealing a compelling link between increased immigration—especially of healthcare workers—and longer lifespans for older Americans. Host David Brancaccio discusses this connection with Brian McGarry, co-author of a recent National Bureau of Economic Research paper, examining how a larger flow of immigrants can improve elder care and prevent thousands of premature deaths among seniors.

Key Discussion Points & Insights

AI-Induced Stock Market Panic

Segment begins at 01:31

• Recap of an unusual stock market selloff.

• A speculative analysis by Citrini Research about AI wiping out the economy by 2028 caused S&P and Nasdaq to tumble over 1%.

• Ben Kumar (Seven Investment Management) remarks on the viral effect of fear-driven scenarios in financial markets.

  “It hit a lot of, I don't know, emotional levers for people, things talking about companies that they use or that they might know. But the difficult thing with AI, with any technology is there historically...always been new jobs created by new technology.”
  — Ben Kumar [02:51]

  • The report offered no new hard data, only a scenario, but struck a nerve with investors.
  • Recent moves: Anthropic rolled out security-focused AI tools, affecting Microsoft’s stock, but Microsoft rebounded slightly.

Immigration and Elder Longevity

Main segment begins at 05:01

• Follow-up to a previous episode on immigrants’ net contributions to the US treasury.

• Today’s focus: Research indicating that higher levels of immigration result in longer lives among Americans aged 65+.

  “What we find is that roughly a 25% increase in the flow of immigrants into the US we estimate would prevent about 5,000 deaths among our nation's older adults.”
  — Brian McGarry [05:38]

• Healthcare System Reliance:

  • US elder care heavily depends on immigrant workers, especially in support roles.

• Job Creation ("Crowd-In" Effect):

  “For roughly about 1,000 new immigrants coming into the US leads to about 173 more healthcare workers, both foreign and domestic...we find actually some, some slight sort of what we call crowd in...”
  — Brian McGarry [06:14]

  • Immigration doesn't displace domestic healthcare workers; instead, an influx increases demand for both immigrant and domestic workers.

• Role of Support Staff in Elder Care:

  “A lot of the care that's delivered is done by what we refer to as low skilled—not to imply that they don't have really great skills, but they don't require the same levels of education. And so that turns out to be a really important part of the health effects.”
  — Brian McGarry [06:59]

  • The benefits largely come from home-based elder care and improved nursing home staffing, provided mostly by less formally educated workers.

• Impact on Nursing Homes and Aging in Place:

  • Increased immigration helps keep more seniors at home rather than in nursing homes, indirectly improving quality and lifespan.

  “Nursing homes are inherently congregate living settings. Those are sort of ripe for infectious disease outbreaks. But we also know that for the most part older adults prefer to age in place than to age at home.”
  — Brian McGarry [07:31]

  • Quality of life likely improves as more seniors remain in their own homes, supported by a robust healthcare workforce.

Notable Quotes & Memorable Moments

• On the Upside of Immigration for Elder Care:
  “By helping older adults age in place and stay in their preferred settings...”
  — Brian McGarry [07:31]

• Clarifying 'Prevented Deaths':
  “So we're showing the prolonged life benefits. But there's reason to suspect that there's also some quality of life benefits at play here as well.”
  — Brian McGarry [07:31]
