Which of the following best describes your neighborhood?

Just about every place that I have ever lived could plausibly be described as a "streetcar suburb", though there is significant variation on that. 

I grew up in a house from the late 1920s, but there's postwar development the next block over and I think it was designed for cars from the beginning.  But the yards are small and the architecture is two stories plus attic, not ranch-style or Cape Cod.  So, kind of transitional between streetcar and postwar.

College was in dorms, but the surroundings were very old suburb with Victorians and a train station.

Post-college (after some time at my parents) I moved to an apartment building in another very old suburb with Victorians and a train station, then I spent a year in Manayunk, which I guess is more urban core (it was all rowhomes, though it switched over to the duplexes of Roxborough not too far from me) except that it also had a sort of separate town feel far from the actual core of Philadelphia.

Then I went to grad school and lived in a Victorian two-family in West Philly.  About as streetcar suburb as you can get, complete with working streetcars.  Then I graduated and stayed there for a little longer.

Now I live in an apartment building in Brooklyn, but there are yet more old Victorians both across the street and down the block, and there's also a subway right nearby.

Europe definitely has "streetcar suburb"-style development as well, and I think that would definitely be a close analogue to the type of greenfield building that happens there, or at least closer than anything else on this list.

Take Milton Keynes for instance:

Milton Keynes is a New Town - a centrally planned settlement - and so has nothing in common with urban development in the U.S. It's grid-based layout is also (famously) unusual and distinctive.

Well, New Towns tend to take their inspiration from the sorts of building forms found in historical streetcar suburbs, so that's why I went with it as the closest analogue.  But yeah, MK is somewhat unique.

The centers of older small towns probably fall under the same banner as well, at least those which have grown to some size or have been swallowed up in some other metro area.
