If one factors out economic / wealth conditions are there any other patterns we can learn from?
Money and sunlight buy you years, all things being equal.
It’s amazing that the wealthier more educated demographic in the USA doesn’t fare so well against the same demographic in other first world countries when it comes to life expectancy. It seems that somehow the demographic shift in the USA didn’t include a cleaner safer environment with less adulterated food sources. An example would be south eastern Pennsylvania that has some of the worst air in the country. Yet, is very affluent. On the nutrition side of it, there is virtually no policing of sketchy food additives. In the USA the supposedly intelligent class is breathing the same raunchy air and eating the same raunchy food.
Is that the case though? Seems like more sunlight in the southern states in red bars vs the green bars with at least NY, MA, if not also D.C.
It appears we should be trying to move to Monaco

The infographic above seems to be inaccurate as China has a life expectancy that is currently higher than the USA and rising faster than the USA.
Can’t comment on the pace, but the many authorities cited here indicate that the US’ life expectancy is still higher than China’s.
Key Takeaways
- U.S. life expectancy at birth for men is about 74, versus 79 for women.
- However as Americans age, their potential lifespan increases as well.
- At 75, an American man can expect to live to 86, which is 12 years longer than the life expectancy at birth.
