Poor die younger than rich in NJ. Here's where the gaps are the biggest.

Only the good die young. Or so says Billy Joel.

But poor New Jerseyans also die younger than rich residents — in some cases by as much as a decade in some parts of the Garden State, according to a study published in the Journal of the American Medical Association.

The study found that from 2001 to 2014 life expectancies increased by about three years for the richest Americans while the poorest Americans saw no change.

The study authors emphasize that the findings don't necessarily mean giving people more money will increase their lifespans. They say the correlation between income and life expectancies may factor in other differences such as education and health behaviors.

Here's a look at the longevity gaps in men and women in all 21 New Jersey counties based on the JAMA data. The life expectancy for the richest New Jerseyans include people who earn in the top 25 percent of income while the poorest New Jerseyans earned incomes in the bottom 25 percent.
