Einwanderung in die Vereinigten Staaten
Transpacific immigration then dried up while the American Civil War took place. It picked up during the period of Reconstruction, but faltered again when Australia was hit by an economic depression in the late 1890s. Immigration to the United States peaked in the years following World War II, due to America's increased economic activity, and the exodus of 15,000 Australian war brides who married U.S. servicemen. From 1971 to 1990, more than 86,400 Australians and New Zealanders immigrated to the United States.
