Probably, no doubt, madam, there were more Norwegians in New York City, than in other parts of the country--one has to remember that New York City has more people, period, than many states--the whole of Nebraska could not even populate mere Brooklyn.
But one wonders what Norwegians did in New York City, since they were culturally-inclined towards (a) farming and (b) fishing, which led most of them to Minnesota, Iowa, and Wisconsin. Surely they were not temperamentally suited for urban factory and service jobs, being too independent for such industrial-revolution servitude.
The Jungle, by Upton Sinclair, tells the "story" of a Lithuanian--which one assumes is "sort of" Scandinavian--in a meat-packing plant in Chicago, and the biggest impression one gets out of that is how such people (Norwegians, etc.) were distorted, contorted, maladjusted, to such work; how it destroyed both their personal and cultural characters.
BTW: I carry a Y-Chromosome, so I am not a madam. :-)
