The graphic shows you the places of origin of the five largest groups of immigrants arriving to the United States in 1910, namely: Germany, Ireland, Canada, Great Britain and Sweden. Among those groups, the one from Germany was clearly the largest, with 2,663,000 millions. Therefore, in 1910 more immigrants to America were born in Germany than in any other country.
