Dillingham Commission Summary

  • Last updated on November 10, 2022

The forty-one volumes of statistical material on immigration eventually published by the Dillingham Commission contained a wealth of information that provided support for limiting immigration, thereby helping lead to passage of the Emergency Immigration Act of 1921 and the Immigration Act of 1924.

During the late nineteenth century, the United States underwent a period of rapid industrialization that required an expanding work force. Immigration supplied much of the new labor needs, and the country’s foreign-born population grew rapidly between 1880 and 1914. Although most Americans thought of themselves as belonging to a nation of farms and small towns, the newest arrivals were predominantly big-city dwellers. New York, Boston, Pittsburgh, and Chicago held the largest immigrant settlements in the United States. By 1910, 79 percent of immigrants from southern and eastern Europe and 68 percent of those from northern and western Europe lived in American cities. The numbers of immigrants from southern and eastern Europe had also been increasing most rapidly, a matter of concern to some native-born Americans. In 1860, only 1.2 percent of foreign-born residents of the United States had come from the southern and eastern countries; by 1910, that proportion had grown to 37.5 percent of the foreign-born.[a]Immigration Act of 1907;and Dillingham Commission[Dillingham Commission]Dillingham Commission[a]Immigration Act of 1921;and Dillingham Commission[DillinghamCommission][a]Immigration Act of 1921[a]Immigration Act of 1924;and Dillingham Commission[Dillingham Commission][a]Immigration Act of 1907;and Dillingham Commission[Dillingham Commission]Dillingham Commission[cat]LAWS;Dillingham Commission[01400][cat]RESEARCH;Dillingham Commission[01400][cat]ANTI-IMMIGRANT MOVEMENTS AND POLICIES;Dillingham Commission[01400][cat]GOVERNMENT AGENCIES AND COMMISSIONS;Dillingham Commission[01400][a]Immigration Act of 1921;and Dillingham Commission[Dillingham Commission][a]Immigration Act of 1921[a]Immigration Act of 1924;and Dillingham Commission[Dillingham Commission]

Background to the Commission

Densely concentrated in the growing cities and distinctly alien in the eyes of many American officials and older American citizens, the new immigrants seemed to represent a problem to groups such as the Immigration Restriction LeagueBoston;Immigration Restriction LeagueImmigration Restriction League of Boston. The trend in political and social thinking known as Progressivism;and assimilation[assimilation]Progressivism contributed to concerns over immigration, because many Progressives believed that solving social problems such as alcoholism, poverty, urban slums, and poor education required improving the human stock of the United States, and they saw continuing immigration as contributing to civic decay. Creating a culturally more unified nation was part of the Progressive ideology. Some political leaders argued that immigrants were flooding into the country in such great numbers that the newcomers could not be assimilated. Progressives also believed that social problems could be solved by the careful scientific analysis of experts.

The desire to bring immigration under control led the U.S. Congress to pass the Immigration Act of 1907. This legislation updated earlier immigration laws and–consistent with Progressive goals ofimproving the American population–excluded persons classified as physically and mentally defective. Section 39 of the 1907 law established a nine-member commission, made up equally of members of the Senate, members of the House of Representatives, and presidential appointees. The task of the commission was to undertake a full examination of the issue of immigration and to prepare a detailed report of its findings, with recommendations for future action, for the U.S. Congress.

Makeup and Mission of the Commission

The U.S. senators on the U.S. Immigration Commission established in 1907 were Republican Dillingham, William P.William P. Dillingham of Vermont, Republican Lodge, Henry CabotHenry Cabot Lodge of Massachusetts, and Democrat Latimer, AsburyAsbury Latimer of South Carolina. After Latimer died in 1908, he was replaced by Mississippi Democratic senator Percy, LeRoyLeRoy Percy. Dillingham chaired the commission, which became known by his name. New Jersey Republican Howell, Benjamin F.Benjamin F. Howell, New York Republican Bennet, William S.William S. Bennet, and Alabama Democrat Burnett, John L.John L. Burnett made up the trio of members from the House of Representatives.

President Roosevelt, Theodore[p]Roosevelt, Theodore;and Dillingham Commission[Dillingham Commission]Theodore Roosevelt appointed three experts to guide the investigation. Jenks, JeremiahJeremiah Jenks, who later summarized the commission’s findings in a book he coauthored with Lauck, W. JettW. Jett Lauck, was a professor, academic researcher, attorney, and respected writer on social and political issues. Neill, Charles P.Charles P. Neill was a former professor of political economy who had entered into public administration. The president’s third appointee, Wheeler, WilliamWilliam Wheeler, was a prominent California businessman.

Members of the commission were generally suspicious of immigration from the beginning, and their preconceptions guided their investigations. Nevertheless, they engaged in detailed and intensive research. In May, 1907, Dillingham, Bennet, Burnett, Howell, Latimer, and Wheeler went to Europe with a commission staff to study the sources of European immigration to the United States. They visited most of the countries that had sent immigrants to the United States and interviewed 108 former immigrants who had returned to their home countries. Within the United States, the commission amassed and organized a vast range of statistics on immigration and immigrants under the direction of Neill and Jenks. The commission also sponsored the research of anthropologist Boas, FranzFranz Boas, who looked at the changes thought to have occurred in the bodies of immigrants and their children. Boas argued that these changes could be taken as physical evidence of the degree of assimilation of immigrants in American society.

Findings of the Commission

The Dillingham Commission concluded its work in 1911. Its official final report filled forty-one volumes and formed a virtual encyclopedia of immigration. The commission presented its conclusions and recommendations in the first volume. The most notable conclusion was that the heavy southern and eastern European immigration of recent years had posed a serious danger to American society by bringing in large numbers of people who were dramatically different from the Elderly immigrants;assimilation ofolder stock of European Americans and who could not be assimilated. The report recommended much more restrictive immigration policies. It also suggested literacy tests to raise the education levels of new settlers.

The Immigration Problem, Immigration Problem, The (Jenks and Lauk report)the summary book based on the report first published by Jenks and Lauck in 1911, is still available in many libraries. It offers an excellent portrait of immigration in the early twentieth century and an illuminating example of how American officials of that era saw immigration.

The findings of the Dillingham Commission helped steer American legislation. In 1917, Congress passed a new law that not only barred all immigrants from a vast zone in Asia but also expanded categories of admissible preexisting immigrant communities and made literacy a requirement for admission for all immigrants above the age of sixteen. In 1921, the Congress enacted the [a]Immigration Act of 1921Emergency Immigration Act, which attempted to limit numbers of southern and eastern Europeans by pegging the number of immigrants permitted from each country at 3 percent of the number of people from that country who had been living in the United States in 1910. The Immigration Act of 1924 made American policy even more restrictive by setting the national quotas at 2 percent of the number of people from each country living in the United States in 1890.[a]Immigration Act of 1907;and Dillingham Commission[Dillingham Commission]Dillingham Commission
