As the economic crisis builds, will we see mass migrations to cities in the US?  That is the phenomenon in other parts of the world:  people move to cities seeking opportunities that do not exist in the countryside.  Shanty towns are constructed on the outskirts, and people eke out a living one way or the other.  There have been reports of tent cities being built in some areas, which could be a harbinger of things to come.  The cities in warmer areas are the ones most likely to experience a massive influx, if it occurs.  They should be thinking about what to do.  These areas that may spring up around cities are termed “peri-urban” and our international aid agencies have experience in with them in other countries. Perhaps these agencies should be consulted.
