To clarify, I meant 80s and 90s suburbs, not the godawful European-looking Stepford-wife monstrosities they build now. Suburbs with tree cover where you may or may not be able to even see the house next door. The kind where every house looks different because it was built by a different company and none of the lots are smaller than half an acre.

That's not very dense even for suburbia. There is a lot of suburban housing from that era that doesn't look like that at all.
