The “Voyage Database” for migration across the North Atlantic was constructed as part of the research for the book, The Business of Transatlantic Migration, between Europe and the United States, 1900-1914, and related articles. In its primary form, the Voyage Database includes:

a) rows for all voyages of regularly scheduled passenger liners between New York, Boston, Baltimore and Philadelphia and European ports, from July 1899 through June 1914.

b) columns of data, including, for every voyage, passenger totals in first, second and third class in each direction, and extensive vessel and shipping line data.

During 1900-14, the four ports of New York, Boston, Philadelphia, and Baltimore received 89% of all immigrants to the United States from anywhere, 93% of all U.S. immigrants from Europe, and about 60% of the entire transatlantic migration flow (across the North and South Atlantic) then.
