And this is a big concern for urban planners -- so big, there's a term for it. The "missing middle." That moniker can be confusing, because it's not directly about middle class housing -- rather, it's about a specific range of building sizes and typologies, including: duplexes, triplexes, courtyard buildings, multi-story apartment complexes, the list goes on.
