A closer analysis of the tables of population reveals some further facts as to the distribution of the different nationalities. The Swedes are the most numerous in Minnesota, Illinois, Iowa, Michigan, Nebraska, and Kansas; the Norwegians predominate in Wisconsin, North Dakota, and South Dakota, and nearly equal the Swedes in Minnesota where each passes 200,000. The Danes are strongest--they can hardly be called a very important factor in any State--in Iowa, Minnesota, Wisconsin, Illinois, and Nebraska; in each State they have more than 25,000. Another feature of this varying density of the three groups has to do with the cities. Chicago, Rockford, Minneapolis, St. Paul, and Duluth account for a large proportion of the Swedes of Illinois and Minnesota, and represent the later rather than the earlier stages of distribution. Outside of the cities mentioned, the Norwegians in Minnesota outnumber the Swedes by some 52,000. In North Dakota, the Norwegians are 72% of the foreign-born Scandinavian population, in South Dakota, 56%, and in Wisconsin, 60%, while in Illinois the Swedes are about 70%, and in Michigan and Nebraska, 63% and 59% respectively. The Danes reach their highest percentages of the Scandinavian foreign-born in Utah, 50%, in Nebraska, 34%, and in Iowa, 23%. Large numbers of the later immigrants, especially of the skilled Swedish laborers, have found occupation in New York and Brooklyn, Boston and Worcester, Hartford and Providence. These have raised the proportion of the Swedes in the United States living in cities of more than 25,000, to 36%, while only 28% of the Danes, and 19% of the Norwegians were similarly located in 1900.[165] [165] _Census Reports, 1900, Population_, I, Tables 33 and 35. Climate, particularly the mean temperature, has also played considerable part in the choice by the immigrants from Northern Europe of the sites for their new homes, though it is an open question whether they would not have been established where they were and when they were even if the climate were different. Certain it is that the few Icelandic settlements are situated in the extreme northern part of Minnesota and North Dakota, and in Southern Manitoba.[166] South of them come, in order, the zones of densest Norwegian population, 49° to 42°, of the Swedish, 48° to 40°, and of Danish, 44° to 38°. The three nationalities thus occupy relatively the same latitudinal position in America as in their homes in the Old North.[167] [166] These are of course enumerated as Danes. Pembina County, in the extreme northeast corner of North Dakota had in 1900 1588 Danes (Icelanders). The movement from Iceland began about 1870. See R. B.
