NYC is forever changing....
In my lifetime I can remember Astoria being pretty solid Irish. Then it was the Greeks that held sway. Now it appears to be the Chinese, although having left Fun City 20 years ago, I can only go by stories like this.
I was born in a Jewish neighborhood- the first gentiles!. By 1947, no Jewish families and it became a min-UN. By 1949, it was predominantly black and by 1951 it was mostly Puerto Ricans. Three turnovers in six years!
