A new study reveals that higher immigration levels significantly increase nursing home care hours and improve health outcomes for elderly patients across U.S. metropolitan areas. The research, led by MIT economist Jonathan Gruber and colleagues, found that a rise in immigrant workers correlates with more registered nurse and certified nurse assistant hours, as well as fewer hospitalizations for nursing home residents.
Immigration Increases Care Workforce and Patient Support
The study analyzed data spanning from 2000 to 2018, encompassing over 16 million Medicare beneficiaries in more than 13,000 nursing homes throughout metropolitan statistical areas in the United States. Using immigration data from the U.S. Census Bureau’s American Community Survey alongside detailed nursing home staffing and patient outcome reports, the researchers uncovered distinct patterns.
For every 10 percent increase in female immigrants in a metro area, registered nurse hours with elderly patients increased by 1.1 percent, while certified nurse assistant hours rose by 0.7 percent. These staffing increases occurred without displacing existing caregivers, indicating an overall expansion of the long-term care workforce.
Improved Patient Outcomes Linked to Immigrant Caregivers
Alongside increased staffing, patient outcomes showed measurable improvement. The study observed a 0.6 percent reduction in hospitalizations for patients on short-term nursing home stays of up to one month. Additional markers included fewer instances of physical restraints, reduced psychiatric medication prescriptions, and a decline in urinary tract infections among residents.
These findings suggest that additional labor supply through immigration directly supports enhanced quality of elder care. The study addresses prior uncertainties about whether immigrants, who may face language barriers or other challenges, would positively impact patient care—concluding that they do.
Why it matters
The study’s results arrive amid ongoing debates over U.S. immigration policy, providing a new perspective centered on public health and long-term care. As the American population ages and demand for eldercare rises, immigrant workers constitute an important component in addressing labor shortages intensified by the COVID-19 pandemic and beyond.
According to Gruber, this research adds a critical dimension to discussions typically focused on crime, taxation, or native employment—showing that increased immigration also improves the care available for older Americans.
Background
The research, published in the American Journal of Health Economics, was authored by Gruber, David C. Grabowski of Harvard Medical School, and Brian E. McGarry of the University of Rochester. Previous work from this team also suggests immigration may reduce elderly mortality rates by expanding access to home-based care.
Following a 10 percent drop in nursing home staffing after the onset of the COVID-19 pandemic, this study highlights the essential role immigrants play in stabilizing and enhancing long-term care capacity.
