The average life expectancy is the longest for people fortunate to be born in these 25 places in the USA, according to a new report from US News & World Report. 

Location and Life Expectancy

Social factors associated with where people live can play a crucial role in shaping their health and well-being. Wealthier and more educated people, for example, tend to live longer than those who are poorer or less educated.

The 2021 Healthiest Communities rankings assess nearly 3,000 U.S. counties and county-equivalents across 84 factors that shape and show the health of a community and its residents, in categories including the economy, equity, public safety, food and nutrition, and housing. The fourth annual project from U.S. News also allows comparisons between communities across these dozens of metrics, which include life expectancy.

These are the counties with the longest average life expectancies at birth for the period 2016-2018, based on data obtained from the University of Wisconsin Population Health Institute’s County Health Rankings & Roadmaps program and incorporated into the Healthiest Communities analysis. Also included are the margin of error for the life expectancy measurements, as well as communities’ overall Healthiest Communities scores, rankings, and population health category scores. The population figures listed are taken from 2019 Census Bureau estimates.

Scores are out of 100 points, and you can learn more about how communities were ranked and scored in their methodology by clicking here.
