Wow, that's very interesting. That stat really separates Canada from the US. I wonder if the ratio was that high in the years leading up to the American Revolution? The melting pot was obviously a success as all Americans banded together to fight the Germans, despite the fact so many have a Germanic lineage.
As of the 1790 census, in the immediate aftermath of the American Revolution, 8.6% of all Americans were of German ancestry. The center of this population was in eastern and central Pennsylvania, with lesser centers in western Maryland, the Shenandoah Valley of Virginia, and the Hudson and Mohawk Valleys of New York. Many of these immigrants moved into the Midwest, following the same paths blazed by the less industrious but more belligerent Scotch-Irish. Interestingly, the German-American commanders in chief in World War I (Pershing) and World War II (Eisenhower) were descendants of colonial era German immigrants, who were raised in the rural Midwest (Missouri and Kansas, respectively) in largely non-German communities.
The political and economic turmoil of 19th Century Germany motivated mass migration to the United States. Additionally, the 19th Century immigration wave included large numbers of German Catholics, which had not been the case in colonial times. West of Chicago, the Catholic hierarchy, historically Irish from Chicago east, takes on a decidedly German flavor. Most of the German immigrants, whether Catholic, Lutheran, or Reformed, settled in the Upper Midwest. Almost one-half of Wisconsin residents have German roots. Except for Texas, this wave of German immigration had little effect on the South.
As for Canada, I thought significant numbers of Germans, Dutch, Scandinavians, and Slavs had migrated to the Prairie Provinces. Wasn't one of their Prime Ministers have the German or Dutch sounding name Diefenbaker?
