[DC] do superheroes routinely check up on the suburbs surrounding cities, or have villains learned to move crime out of urban areas?

It's been seen on occasion. Spider-Man once had a very difficult time tracking down a criminal who commuted into NYC from the suburbs. (ASM 267, "The Commuter Cometh!", which was paid tribute to in Spider-Man Homecoming)

Supervillains are likely easier to spot and track in suburbs and unless they're in particularly wealthy areas then there isn't enough payoff to make it worth the risk.
