Why Is This Important?Life expectancy is a summary mortality measure often used to describe the overall health status of a population.
How Are We Doing?Life expectancy is slowly increasing among all racial and ethnic groups as well as among both males and females, although the increase has mostly stalled in the period 2012-2014. As of 2014, the average life expectancy among New Jersey residents was 80.9 years. Life expectancy among females (83.2 years) remains about 5 years greater than among males (78.5). Among New Jersey residents, life expectancy is highest among Asians (90 years), followed by Hispanics (84), Whites (81), and Blacks (77).
To compare life expectancy geographically, visit the RWJF's [https://www.rwjf.org/en/library/interactives/whereyouliveaffectshowlongyoulive.html data interactive] to compare a neighborhood to its corresponding county, the state, and the U.S.
How Do We Compare With the U.S.?Life expectancy among New Jersey residents is slightly greater than that of the nation as a whole.
