How does that make it meaningless? Yes, certain segments of the population are even more underserved than others, but that’s just more evidence for the fact that we’re doing a crap job of keeping people healthy.
None of the top 5 has any real correlation to a geographic area per se.
Thus "Depending on Where You Live" isn't really a great title.
Because by not breaking out the single largest compounding factor, it's masking the real problem underlying this issue: there's a massive disparity in outcomes for people of different races.
In Washington state, the counties with the worst mortality are 95% white, with 5% native (Grays Harbor and Okanagan)
(poverty, education, race are of course very correlated)
You're asking if I have evidence that the IHS is an absolute disaster, which impacts mortality rates and life expectancy?
Yes, that's a problem that's been very well-documented for the past seventy years.
And it's not just because minority populations have worse access to healthcare. There are in fact genetic components that predispose different races to different diseases.
Japanese people, Glaucoma. AA, heart disease. White people, Celiac.
Basically there's multiple components: Race, Healthcare access, Poverty, Education, Local Cultural proclivities for: diet, exercise, etc.
