If I'm reading the article correctly it's a rather misleading headline. When I see healthiest states I'm think physical health of the people that live there. Instead they have include multiple factors including financial. You can have a bunch of money and still be a fat slob. You can be in great shape and not be rich. Kind of a weird article.
I believe they are measuring overall health
"The research assessed the well-being across a range of individual health risk factors – their physical health, community and social bonds, ability to manage their finances to achieve their goals, and strength of purpose in daily life – and analyzed more than 600 elements of social determinants of health to identify those most associated with community health outcomes – healthcare access, food access, resource access, housing and transportation, and economic security"
