The 50 US states ranked from most to least healthy

Not all states are created equal when it comes to health.

To get a better sense of how healthy each state in the US is, for the 28th year in a row, the United Health Foundation has ranked America's states.

Massachusetts made the top of the list as America's healthiest state, while Mississippi was declared the unhealthiest.

Looking at data from the Centers for Disease Control and Prevention, the American Medical Association, and the Census bureau, the rankings took into account everything from obesity and smoking to community and environmental factors, such as child poverty and air pollution, to public policies like immunizations, and health outcomes like cancer deaths and diabetes.

At the same time, the UHF noted some troubling trends: premature death (that is, deaths that occur before an older age) rate and the drug death rate have both been increasing.

Here's are all 50 states, ranked from healthiest to least healthy.
