After 1855, the tide of immigration began to decrease steadily. During the first two years of the Civil War, it was less than 100,000.[1] In 1863, an increase was noticeable again and 395,922[2] immigrants are recorded in 1869.
During all these years up to 1870, the great part of the immigration was from Northern Europe. The largest racial groups were composed of Irish, Germans, Scandinavians and French. About the middle of the nineteenth century French-speaking Canadians were attracted by the opportunities for employment in the mills and factories of New England.
The number of Irish coming here steadily decreased after 1880 until it has fallen far below that of other European peoples. Altogether, the total Irish immigration from 1820 to 1906 is placed at something over 4,000,000, thus giving the Irish second place as contributors to the foreign-born population of the United States. The Revolution of 1848 was the contributing cause of a large influx of Germans, many of whom were professional men and artisans. From 1873 to 1879 there was great industrial depression in Germany and consequently another large immigration to America took place. Since 1882, there has also been a noticeable decline in German immigrants. From 1820 to 1903, a total of over 5,000,000 Germans was recorded as coming to the United States.[3]
In the period from 1880 to 1910 immigration from Italy totaled 4,018,404. It will be remembered that the law requiring the registration of outgoing aliens was not passed until 1908, and it may, therefore, be estimated that
