C) close to people of similar ethnicities, cultures, and religions
It has been suggested repeatedly that migrants to the United States chose areas that were environmentally similar to their European homes. The substantial Scandinavian settlement in Minnesota and the Dakotas is indicated as a case in point. There may be some small truth in this, but it was more important that those states represented the principal settlement frontier at the time of major Scandinavian immigration. For the most part, the mosaic of ethnic patterns in America is the result of a movement toward opportunity--opportunity first found most often on the agricultural settlement frontier and then in the cities.
