scholars have also researched how cities outside of the united kingdom and the united states have developed, but only to a limited degree. urban history previously focused mostly on how european and american cities developed over time, instead of focusing on how non-european cities developed. additional geographic areas researched in this field include south africa, australia, latin america, and india. this is changing as more research is performed in developing economies, leading to more contextual urban and infrastructural development in various parts of the world.
