I don't even know, like, where I live is a bit of everything. We have tons of farms and ranches, but I like in a gated community that's like a suburb. So it's like rural and suburban at the same time? Hard to explain.
I guess it's kind of subjective. I think of population density and traffic as the main factors. Cities have their gated communities with large houses, but I'd say that if you live very close (like a 5-10 minute drive) to an area with a large population density, then I'd say you live in an urban area. If most of the houses in the town or city you live in are spread out, then I'd say you live in the suburbs.
I live in the most suburban place to ever suburb. Like, there are identical houses and townhouses for MILES. Also, my town is like, 95% white, which is really uncomfortable at school because, everyone's white and, I'm not.
