It's possible on the west coast that have older chinatowns, on the east coast chinatowns just followed the immigration trend. Most are based around where previous immigrant groups settled than moved away. Chinatown new york was an italian enclave, chinatown boston was an irish enclave. Newer ones formed because of racial and economic reasons. C-town brooklyn and queens are newer and the families that live around there are financially better and socially more integrated in the area. The story I was told is you land in Manhattan, buy your first apartment in brooklyn and buy your first house in New Jersey or Connecticut.
