Here are the healthiest (and least healthy) counties in New Jersey

The healthiest counties in New Jersey in 2022 are also the wealthiest and, by chance, located in the state's pharmaceutical belt across Central Jersey.

Morris County again tops this year’s list of the healthiest of the Garden State’s 21 counties, followed by Hunterdon and Somerset, the same rankings as in 2020 and 2021.

Middlesex moved down one place to sixth — the same spot it held in 2020 — while Union stayed steady in eighth. Bergen came in fourth place and Sussex made an appearance into the top 5.

The annual rankings are compiled by the University of Wisconsin Population Health Institute with support provided by the Robert Wood Johnson Foundation.

Somerset has the highest median family income in the state, followed by Hunterdon and Morris. Middlesex ranks sixth while Union is 11th.

Five of the seven least healthy counties are in the southern part of the state, with Salem and Cumberland at the bottom of the rankings. Passaic and Essex, at 16th and 17th places, respectively, are the two North Jersey counties in the bottom third.

Unlike 2021, this year's study includes the impact of the COVID-19 pandemic. According to the study, the pandemic both revealed and worsened the burdens and barriers that women, people of color and low-income people face.

In addition to the toll the pandemic took on physical and mental health, COVID-19 occurred at the intersection of multiple national crises — from racism to climate change — and continues to have wide-ranging negative impacts on the social and economic health of the nation, the study concludes. COVID-19 was the third leading cause of death in 2020 and 2021.

Here are some key facts from the county rankings:
