What is the rust belt in your country? These are areas once very prosperous now in a precipitous decline. These days, it is often areas of heavy industrial production that have moved away and with it the jobs and people. In Canada, it's mostly in the Southern Ontario (like Windsor, Hamilton, Oshwa, etc.) where much the auto industry is located, and it contiguous with the rust belt of the United States (Michigan, Upstate New York, Ohio, etc.).
I'm a little uncertain about the rest of the world. Since the 1980's the old industrial heartland of England has fallen on rough times. I've heard Walloon was heavily industrial and fallen on hard times. I've remember reading about how much of former East Germany is falling into decay. Even though China is growing economically, much the North could described as a rust belt, where the government has set up plans to try and kick start its economy. Correct me if I am wrong.
