Remember that the reverse would be true as well though. I could easily vet all the crazies out of a particular area. "This guy is a homophobe, this guy is racist, this guy a violent white supremacist as of July 15 2014. So I won't move into that neighborhood."
A person who fears for life due to their personal identity probably would be a bit adept at vetting potentially dangerous areas.
And if you're oh, say an atheist in a place like Pakistan, you do what exactly...look online to see that there's quite literally no where for you to go, have a nice glass of wine, and wait for your violent death?
For that matter, whatever gave you the idea that most people get to choose what neighborhood they're going to live in? Poor people pretty often live wherever fate deposited them. The whole idea reminds of a joke Bill Maher made during the Hurricane Katrina aftermath, the gist of which was George Bush saying something to Cheney like, "I don't understand what all those people are still doing in the Superdome. Why don't they get in their SUVs and drive to their summer homes?"
Atheism as such isn't usually such a big deal in Pakistan, what gets people's goat is the whole insulting Mohammad thing. In practice people usually leave atheists alone. But yes, I see your point.
