The great majority of Baghdad is a slum - a lot of it's new, but it's still slum. It's usually this concrete-block, one-room design with a door and a window, arranged one-up, one-down, often with a shop with nothing in it on the first floor, and then a one-room apartment above it. There's street after street after street of that stuff.
