It might be great to live in Thailand where you have to spent just a little for living but what happens if we compare this with their healthcare system?
After all, if you don't like it in a place (or you're not happy with the public services) you can just up and leave.
Having said that, it'd still be nice and make the data inherently more useful to have additional data such as the quality of/access to healthcare (though I'm not sure how easy it is to quantify that) or crime rates.
None of the cities on the list so far are anywhere I'd be desperately worried about being sick.
That's probably true for most major cities outside of the US.
