Is Urban/Suburban/Rueal more about cencus area or lifestyle? I’d argue that there are plenty of North America cities with suburban population cores, because it’s all single-story buildings and parking lots until you hit the few ofice towers. Heck, the tallest building in my city might be a grain silo.
Also, looking around at the buildings near where you live is a lot easier than looking up census data, so you’d probably get more results that way.
On one hand, I’d argue it was the British who started that.
On the other hand, we definitely didn’t stop it.
