Yes a bit biased, but fascinating and telling. The researchers rearranged the richest and poorest counties into "states" and then analyzed these new "states".
The rich outlive the poor by up to 9.5 years in the United States, study says | News & Observer:
"The poorest “state” was made up of actual counties from Alabama, Arkansas, Georgia, Illinois, Kentucky, Louisiana, Mississippi, Oklahoma, South Carolina, South Dakota, Tennessee, Texas and West Virginia.
The richest “state” included real counties from Alaska, California, Colorado, Connecticut, Georgia, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Minnesota, Ohio, New Jersey, New Mexico, New York, Pennsylvania, Utah, Tennessee, Texas and Virginia. (It’s worth mentioning that five real states contributed counties to both the poorest and richest “states.” This shows that “some of the challenges associated with poverty in the United States are related to factors associated with unequal distribution of resources within states, as opposed to simple lack of resources,” the researchers wrote.)"
"In other words, they wrote, “the poorest ‘state’ is between 40 and 50 years behind the life expectancy achieved by the wealthiest ‘state.’ ”The study authors also compared the richest and poorest “states” to 222 actual countries with reliable data on life expectancy. They found that if the richest “state” were an independent country, it would rank eighth in the world in life expectancy for men and 25th for women. The poorest “state,” on the other hand, would rank 123rd for men and 116th for women."
