A child born in the United States in 2014 can expect to live 79.1 years, on average.
But that figure doesn’t apply equally to all kids across the country. For example, a baby boy born in South Dakota’s Oglala Lakota County that year has a life expectancy of just under 62.8 years. Meanwhile, a baby girl lucky enough to be born in Summit County, Colo., can plan to live to the ripe old age of 88.5.
That’s a difference of more than 25 years. Put another way, the girl in Colorado can expect to live 41% longer than the boy in South Dakota.
These figures come from a new analysis of life expectancies in more than 3,100 counties in the 50 states plus the District of Columbia....
