I am interested in possibly going into urban planning but I am unsure of a few things. First, are there companies out there that's primary purpose is urban planning? Second, is urban planning mainly a localized job, meaning you work in one city or area, or can urban planners travel all over the country or even the world assisting cities in planning developments? Finally, is urban planning a dead end job or can you get a bigger and more high paying job the harder you work? Any response is appreciated.
