"...socially organized or cohesive communities are better able to engage in informal social control that can lead to lower levels of crime than communities that are not cohesive..."

I live in the East End of Pittsburgh, and have also lived in DC and downtown in other cities, and I taught HS in Charm City. Other than recent immigrant communities, no other community is as cohesive as the black community. I don't know of a single person in the Pittsburgh suburb I grew up in that is still there. All the kids moved somewhere else, and the adults died. But families go on and on in urban communities, living in the same neighborhoods over generations because many people don't leave. Everyone knows everyone else from the public schools, church, and family relationships. If a lot of people don't have cars they will see each other on the street all the time. Everyone also knows everbody else's business too.

In safe suburban neighborhoods people live 50 feet from each other and it might as well be a river. If they're organized, it's one of those hateful HOAs that keeps an eye on your lawn. But mostly everyone is doing their own thing while keeping one eye open for each other's safety and property. They rely on law enforcement for that as well, which I understand is a problem in the urban black community. No one in the city is going to narc on their family, or someone they went to high school with or their cousin, and you can't blame them for that. If you know several people including family who are incarcerated, the police are not your friend and you're not going to help them in any way. In the suburbs if some neighbor disturbs the peace or messes with anyone's property, away with them.

Both communities are very difficult to organize by the way. Political organization in the black community has historically been done by the black churches, and I guess we will see if they can be replaced because not everybody likes church. They have buses.
