REPORT OF THE IMMIGRATION COMMISSION OF 1907
In point of fact, the only substantial body of statistical information about the naturalization of the foreign-born voter which hitherto has been even ostensibly sufficient for the student as a basis for any racial comparisons, is that gathered by the United States Immigration Commission of 1907. That body, created by an Act of Congress approved February 7, 1907, of which Senator William P. Dillingham of Vermont was chairman, consisted of three Senators, three members of the House of Representatives, and three other persons appointed by the President of the United States, and was directed by the statute to “make full inquiries, examination, and investigation, by sub-committee or otherwise, into the subject of immigration, ...” and to report such conclusions and recommendations as in its judgment might seem proper.
The information gathered by this Commission is very voluminous, and has been of great value to sociologists and others concerned with various aspects of the subject. Indeed, its report has come to be called “the bible of the immigration question.” Nearly all the modern writings on the subject have been based upon it in at least a general way, and their color taken largely from its conclusions and its point of view.
