In my early "independent" years I lived in the heart of the city, right near downtown, because that's where the affordable housing was. Now I live in a suburb, because that's where the affordable (relatively) housing is. The in-city neighborhoods where I once resided are now gentrified. I have to resist rolling my eyes at the self-congratulatory newcomers to my old neighborhood who crow about how they "treasure the diversity" there. If by "diversity" they mean people of many racial and ethnic categories in significant numbers, well, the district is made all the less diverse by the newcomers' presence. There's more diversity in the suburb where I now live.
