Do you have any cites for that data? What is success defined as? I've heard that causation thrown around lately but have never seen the actual study.

I can see it at the extremes, meaning Martha's Vineyard and Compton perhaps as examples of positive and negative predictors. I haven't visited either, so I wouldn't know first hand. The vast, vast majority of zip codes aren't the extreme by definition. In my zip code, there are both wealthy people in million dollar properties as well as HUD housing and the majority somewhere in between.
