It isn't cheap, and perhaps more importantly, it doesn't have the social life and other draws that Brooklyn does. Unless hipsters suddenly get into bachata and reggaetón, the Bronx largely lacks the sort of nightlife and businesses that might otherwise attract them in spite of the price.

Yeah, this was me when I moved to the Bronx. I was in the same apartment for 11 years, and the only other white people I saw in my neighborhood were police, the odd school teacher commuting and the Mormon kids that got sent to evangelize around Highbridge and Mount Eden instead of at least getting a trip overseas out of their mission.

I would also say this study conflates living in the same neighborhood with actual diversity and integration in the community. Sure, my neighborhood had Dominicans, Mexicans, Africans, Haitians, African Americans, etc. all living in the same buildings, but they largely maintained their own segregation. One thing I think gets overlooked by better off white people who never actually live in these neighborhoods and only speak English is the amount of flagrant racism between minority groups. Hispanic groups vs Black people, Africans versus African Americans, then disputes within those groups as well.

A lot of the Bronx "gentrifying" just seems to me to be the real estate industry trying to manufacture it and raising prices hoping to get some idiots who'll fall for it. When I worked in Mott Haven, there were already buildings going up trying to charge $2500/month for a studio to live 6 blocks away from the train in the hood. There have been some hip businesses that opened up on Alexander and Bruckner, but you have literally a single hipster block where you see white people, then they hop in their cars and disappear.
