Researchers examined life expectancy statistics in the United States for 2010-2015 and found that more than 75% of the total variation in life expectancy was attributable to census tracts; census tract-level socioeconomic and demographic variables, such as age, income, and race/ethnicity, were highly associated with life expectancy, suggesting that longevity inequality has a strong local geographic aspect, according to the authors.
