I'm thinking interiors strictly. Specifically lower middle class or working class Kingston Jamaica, San Jose Costa Rica, Shubra/Cairo Egypt, Johannesberg South Africa, Kinshasa in Congo or Nairobi Kenya. All apartments in any city are different from each other but certainly from a single photo you can usually tell if an apartment is in Central America, the Middle East, Africa or the USA/Canada unless it is a very luxury style apartment. I guess Central American is most similar to US but Egyptian apartments for instance have consistently different living, cooking, washroom and sleeping set-ups then you ever see in the US in my experience at least at the working class income level of my relatives and their neighbors. The wall colors etc are very different too.

Really I would love a normal working class US apartment for Poser as well. In my experience living all over the North East US many working class apartment are very 50's era. Even when I lived in Boston and for many years in Manhattan my friends and I all lived in places from circa 1910-1950. I have used Mapp's WWS6 - The Hotel kit to make rural Vermont apartments although things like the doors had to be changed. The closest I have found to a New York or Montreal apartment is ockham's 50's kitchen. I have lived quite a few places in New England, the US South and even Alaska and they all had destinctive interior architecture and typical furnishings. I think there are far more European middle class interiors like greenpots' available for Poser then US style for some reason.
