I think the point was that the "urban area" definition in the census was quite broad. I live in an "urban area" on a decent plot of land with a Christmas tree farm on one side and a working farm/apple orchard on the other. Probably not what most people think of as urban.
My parent's house has an orange orchard in front of it, a wilderness area behind it, but Uber rides from downtown are still only $11, and everyone I know who lives in that town now uses Uber instead of driving. DUIs are way down. Nightlife is better, etc. etc. This is a very real 'urban' situation.
It is relatively broad, but the point is that it's based on population size and density. The fact that you live next to a farm and an orchard doesn't change the fact that you live near lots of other people.
I suppose it depends on your definition of near. I'm about an hour drive from a major city. Less so to smaller urban areas that have no significant public transit. No it's not the wilds of Wyoming but most people here probably wouldn't consider being on a 100 acres or so with a couple of other houses being near lots of other people.
