Data Story
About Health in Mercer County, New Jersey
Mercer County life expectancy near national average
Mercer County's 78.4-year life expectancy is roughly in line with the US average of 77.2 years, though the county's 14.8% poor or fair health rate exceeds the national average of 13.1%. This reflects mixed health outcomes across the population.
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
At 8.7% uninsured, Mercer County exceeds neighbors Middlesex (7.3%) and Monmouth (6.1%), though the county excels with 410 mental health providers per 100K—the highest ratio in the state. The 90 primary care providers per 100K suggest adequate capacity, but insurance coverage gaps persist.
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.
