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 was slowly increasing among all racial and ethnic groups as well as among both males and females until 2015. Small declines in overall life expectancy have been experienced each year since then.
As of 2018, the average life expectancy among New Jersey residents was 80.4 years. Life expectancy among females (82.9 years) remains five years greater than among males (77.8). Among New Jersey residents, life expectancy is highest among Asians (92.2 years), followed by Hispanics (85.5), Whites (79.8), and Blacks (76.5).
By county, estimates range from 75.1 years in Cumberland to 84.0 years in Hunterdon.
How Do We Compare With the U.S.?Life expectancy among New Jersey residents is slightly greater than the U.S. estimate of 78.6 years. [https://www.cdc.gov/nchs/fastats/life-expectancy.htm ^1^]
