The ability to survive doesn't seem tied to anything you mentioned except maybe to working genitalia, for example if you are born in a country with good health care (e.g. Canada) you are more likely to survive than a country with bad or mediocre health care -regardless of any other criteria-; wanting kids and having kids are not as correlated as expected, is easy to see that in the tons of unwanted teenage pregnancies, "attract a partner" is so subjective that it doesn't lean to any population in particular, you can see that when even male meth-heads living in SUVs have a girlfriend with similar issues; in general healthcare has improved so much that now lifespans are pretty much leveraged regardless of most other variables meaning is likely natural selection no longer plays such a major role as it did in previous generations.
