Slightly below New Jersey average

Mercer County's 78.4-year life expectancy falls just short of New Jersey's state average of 78.5 years by 0.1 years, placing it in the middle tier statewide. The county's health challenges require targeted interventions in primary care and insurance access.

Higher uninsured rate than peers

Insurance barriers complicate care access

Mercer County's 8.7% uninsured rate means roughly 50,000 residents lack health coverage, making preventive care and emergency treatment unaffordable for many. With 90 primary care providers per 100K, supply meets demand, but uninsured residents struggle to utilize available providers.
