You realized you just dismissed GDP per capita, a quantitative metric, as too “flawed”, then instead relied on HDI which entirely a made up metric based on subjective measures?
You might not like the magic numbers in the formula or the things they choose to weigh, but GDP is much, much too coarse to evaluate anything about the greater well-being of a population, especially in developed countries.
In the very least you'd have to adjust for purchasing power parity and look at the median rather than the mean, to say anything useful about quality of life for normal people.
Yes, I agree. GDP is a very rough measure. I'd prefer PPP, but I couldn't find it for individual states after a cursory search. (I still think most readers will be surprised by Alabama's GDP, relative to wealthy European nations, so it's not totally useless.)
