Guadaloupe (a French island dominion in the Caribbean) has neighborhoods like this (black communities -- most of the black people descend from former slaves and have been there for generations). I heard about this on a podcast discussing a recent finding that the Guadaloupe Raccoon was actually the same species as the common North American raccoon and was hence subject to EU pest control regulations. The Guadaloupe raccoon had been a common pet up to then -- and police began raiding neighborhoods with large teams to take people's pet raccoons into custody. These raids were often quite tense and dangerous. I mention this to provide a case which demonstrates 'no go zones' that do not involve immigration. Its my guess that immigration is almost never the cause of a no-go-zone neighborhood -- I think such neighborhoods are almost always the result of real systemic social biases that cause socio-economic problems.
