if you have a substantial number of people whose lives are curtailed below the national average lifespan due to causes associated with deprivation -- malnutrition, exposure, life in insecure "war zones" rife with violence and virtually unpoliced, arbitrary violence from whatever police presence there is -- then I think it is safe to say that you have substantial poverty.
it is possible to be "wealthier" in terms of good diet, personal security, health and longevity as a cash-poor peasant in a supportive cultural matrix than as a working-poor American through whose hands more dollars flow each year. so I would stick to actuarial stats if I were trying to figure this out.

As to the part about "life in insecure war zones" (and I'll have to find the link) a study came out not too long ago showing that children in some areas of our inner-cities do suffer ptsd and all the associated problems of living in this way.
Honestly, we can talk about jobs and the economy and education -- and those are all good things -- but I think if I could choose just two things to change that I believe would help the most, I'd choose national healthcare and ending the drug "war." Maybe we can eventually make language a complete impediment to understanding. -Hobbes
