I think there's a been a substantial change in the kinds of suburban developments. I grew up in suburbia but it was still significantly more walkable than the sorts of developments I see today, especially in areas where housing is cheap and they're building a lot. My suburb growing up was grid based and you could bike to the grocery store. The part of Portland I live in is technically a suburb (started out that way, but eventually merged into the core). However, based off of historical records, the basic pattern of businesses has remained the same, so even when it was fully suburban, you could always walk to the park , coffee shop, bakery (some have even been here the full 100 years or so the neighborhood's been around). Whereas, due to zoning and HOAs, I just can't see where those would possibly develop in the example I gave above. It's illegal. I'm not an expert by any means, but I feel the pattern changed sometime in the 90s and aughts.
