What Country Does Your State's Life Expectancy Resemble?
American life expectancy has leapt up some 30 years in the past century, and we now live roughly 79.8 years on average. That’s not terrible, but it’s not fantastic either: We rank 35th in the world as far as lifespan, nestled right between Costa Rica and Chile. But looking at life expectancy by state, it becomes clear that where you live in America, at least to some extent, determines when you’ll die.
Here, I’ve found the life expectancy for every state to the tenth of a year using the data and maps from the Measure of America, a nonprofit group that tracks human development. Then, I paired it up with the nearest country by life expectancy from the World Health Organization’s 2013 data. When there was no country with that state’s exact life expectancy, I paired it with the nearest matching country, which was always within two-tenths of a year.
There’s profound variation by state, from a low of 75 years in Mississippi to a high of 81.3 in Hawaii. Mostly, we resemble tiny, equatorial hamlets like Kuwait and Barbados. At our worst, we look more like Malaysia or Oman, and at our best, like the United Kingdom. No state approaches the life expectancies of most European countries or some Asian ones. Icelandic people can expect to live a long 83.3 years, and that’s nothing compared to the Japanese, who live well beyond 84.
Life expectancy can be causal, a factor of diet, environment, medical care, and education. But it can also be recursive: People who are chronically sick are less likely to become wealthy, and thus less likely to live in affluent areas and have access to the great doctors and Whole-Foods kale that would have helped them live longer.
It’s worth noting that the life expectancy for certain groups within the U.S. can be much higher—or lower—than the norm. The life expectancy for African Americans is, on average, 3.8 years shorter than that of whites. Detroit has a life expectancy of just 77.6 years, but that city’s Asian Americans can expect to live 89.3 years.
But overall, the map reflects what we’d expect: People in southern states, which generally have lower incomes and higher obesity rates, tend to die sooner, and healthier, richer states tend to foster longevity.
