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.
