ujm, how are Jewish pattern different here? Are you claiming that Jews lives among Indian tribes first!?
During most migration, most Jews arrived to NY and other big NE ports. There were minor periods when there was migration to small NE towns, and eary on Reformim sponsored Eastern European plebeians to go to Texas not to embarrass them in from of the society. Then, they started moving out of big cities to suburbs and to the rest of America just like the goyim. True, Jews go to NYC for yeshivos and colleges, pick up cheap(er) kosher food, and on the way to EY, but this does not deny the main thread that they (or their parents) previously left the cities. This is _way_ different from Jews in Ukraine Pale who are moving to a big city.
