The data you've presented just don't allow us to make those claims, and fall apart at the gentlest interrogation:

- much doesn't relate to hunter-gatherers at all - some is a tiny sample size (in the only case I dug into, n<=1!) - the bulk of it involves peoples under pressure from encroachment (and worse) - by its nature it's woefully incomplete, some of it cherry-picked, and ignores the majority of hunter-gatherer peoples

It's a fascinating and important question, though.
