I call BS on this. Which neighborhood you live in or whether they are your “peeps” has nothing to do with whether you’ll get cancer. Nothing. What an incredibly stupid study.
One might have expected the opposite. The 99% black areas tend to be impoverished compared to the mixed areas. Think Anacostia vs. Prince Georges County, MD, for instance.
So maybe a strong social network is more important for maintaining health than a higher income? That is interesting.
Ah, but you have to understand the reasoning for it. It means now it's okay for hispanics and blacks to segregate themselves for their health. Whites will still be expected to "diversify".
