 Life expectancy rates have been on the rise in the United States with an increase of nearly seven years over the past half century. The average lifespan was 70.8 years in 1970, documented as 77.5 in 2022. There also seems to be a variability depending on where you live. For example, in a list of places with the longest longevity, coming in at number five is Rutherford County, where life expectancy is 76.2 years.
