A County Health Rankings report finds a strong correlation between income and health, at least in New Jersey’s wealthiest and poorest counties, reports NJSpotlight.

Released today by the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute, the report found Hunterdon County, which has the highest median household income in the state, also ranked healthiest, while Cumberland, with the lowest income, ranked worst. The report scores counties based on health outcomes — such as premature death, low birth-weight babies, and poor health days — and the factors that influence them — including rates of smoking, obesity, and unemployment.
