Demographics drive everything we do; no one wants to be close to crime, you don't need a marketing for that: it advertises itself.

Sure but that presumes that where and how bad the crime is is an understood fact and people make decisions accordingly, when the evidence says the opposite. Over-policing in predominantly minority areas cases more crimes to be reported as occurring, even when the actual crime rates are more or less equal between those areas and predominantly white areas, simply because more police and police resources are allocated to those areas, and therefore, more crime is discovered and prosecuted. This becomes a death spiral for neighborhoods: more police presence equals higher crime statistics which in turn are used to justify increasing police budgets and police presence in those same areas, and, worst of all, those areas never actually become safer for the people who live there, often the exact opposite.
