Methodology

To determine the counties where people live the longest, 24/7 Tempo reviewed 2014 county-level life expectancy at birth figures provided by the Institute for Health Metrics and Evaluation (IHME), a global research center affiliated with the University of Washington. Data came from the report, “United States Life Expectancy Estimates by County 1980-2014.” Using death records data from the National Center for Health Statistics, researchers estimated age-specific mortality rates for U.S. counties from 1980 to 2014.

County-level poverty rates came from the U.S. Census Bureau’s 2017 American Community Survey. Obesity rates came from The 2019 County Health Rankings & Roadmaps program, a collaboration between the Robert Wood Johnson Foundation and the University of Wisconsin Population Health Institute.
