Book excerpt: Dr Cohn provides an in-depth and comprehensive analysis of the economic history of European immigration to the antebellum United States, using and evaluating the available data as well as presenting fresh data. This analysis centers on immigration from the three most important source countries - Ireland, Germany, and Great Britain - and examines the volume of immigration, how many individuals came from each country during the antebellum period, and why those numbers increased. The book also analyzes where they came from within each country; who chose to immigrate; the immigrants' trip to the United States, including estimates of mortality on the Atlantic crossing; the jobs obtained in the United States by the immigrants, along with their geographic location; and the economic effects of immigration on both the immigrants and the antebellum United States. No other book examines so many different economic aspects of antebellum immigration.
