PIONEER NORWEGIAN SETTLEMENT IN MINNESOTA (PDF) See page 21 of 35(PDF) for distribution of Norwegian settlement. According to the monograph, Norwegians skipped the areas east of the Mississippi as less fertile (and more trees).
In 1940, the foreign stock (foreign born and children with at least one foreign-born parent) was:
Germany: 266,707
Sweden: 229,121
Norway: 228,965
Given this reality, why is there a perception (among some) that Minnesota is Norwegian?
I think the link is wrong; it appears to be some community paper in Texas.
Interesting thread, btw.
