Reality is what removes the bias more than anecdote, and statistics is what tracks these facts.
It would negatively biased if it was more of corner cases than not.
Meanwhile, the more wealthy neighborhoods are full of busybodies sniffing around for the slightest HOA infraction, and high-anxiety individuals reflecting and amplifying each other's tensions. Each home is a fortress unto itself. I feel pretty lucky to be in the middle, where we don't have as much crime as the poorer areas, but we still know one another, and still trade food on the holidays.
Wealthier neighborhoods tend to have massive buy-in from the residents, because who wants to lose something that nice?
Point being: the experience is best when avoiding extremes. Poverty and incredible wealth both lead to issues in a neighborhood.
Wealthy white collar suburbs almost universally suck because people don't really miss out on much by not interacting with each other and people have no real problems so they tend to make each other their problems and not like what their neighbors do.
You go down the economic ladder and things get a lot better because people have enough real problems they don't give a shit about whether their other neighbor pulled permits or what the setbacks are or how long their project car/boat has sat on blocks, and they interact with each other because being friends with your neighbors well enough to share tools and trade favors is worth it.
