In 1907 the U.S. Congress created a joint commission to investigate what many Americans saw as a national crisis: an unprecedented number of immigrants flowing into the United States. Experts—women and men trained in the new field of social science—fanned out across the country to collect data on these fresh arrivals. The trove of information they amassed shaped how Americans thought about immigrants, themselves, and the nation’s place in the world. Katherine Benton-Cohen argues that the Dillingham Commission’s legacy continues to inform the ways that U.S. policy addresses questions raised by immigration, over a century later.

Within a decade of its launch, almost all of the commission’s recommendations—including a literacy test, a quota system based on national origin, the continuation of Asian exclusion, and greater federal oversight of immigration policy—were implemented into law. Inventing the Immigration Problem describes the labyrinthine bureaucracy, broad administrative authority, and quantitative record-keeping that followed in the wake of these regulations. Their implementation marks a final turn away from an immigration policy motivated by executive-branch concerns over foreign policy and toward one dictated by domestic labor politics.

The Dillingham Commission—which remains the largest immigration study ever conducted in the United States—reflects its particular moment in time when mass immigration, the birth of modern social science, and an aggressive foreign policy fostered a newly robust and optimistic notion of federal power. Its quintessentially Progressive formulation of America’s immigration problem, and its recommendations, endure today in almost every component of immigration policy, control, and enforcement.

"These days virtually all historians revile and reject the Dillingham Commission. Benton-Cohen reveals, however, that the Dillingham reports, which did not always support the Commission’s recommendations, tell us a lot about a time, not unlike our own, of ‘simultaneous suspicion and celebration of immigrants, fear of government power and confidence in public policy, need for manual labor’ and concern about wages and jobs for so-called Anglo-Saxon Americans." - Forward

"In 1907, Congress authorized the largest study of immigrants in American history. Though many may not know of the Dillingham Commission, Benton-Cohen ably examines the bipartisan special committee and its abstract purpose…Benton-Cohen places the committee in its historical context, demonstrates the emergence of the social norms during the Progressive Era, and successfully relays how immigration policies of the early 1900s still resonate today." - Library Journal (starred review)

"With thorough research and compelling evidence, Benton-Cohen’s book is not only an essential read for immigration historians but also an invaluable addition to a growing literature on the Progressive Era. As questions about the ‘immigration problem’ are intensely debated in the U.S. today, this book will help us reflect on its origins." - H-Net Reviews

"Important and timely…Contains a fascinating discussion of the categories developed for ‘race’ and ‘nationality’ among immigrants…Of particular interest is [Benton-Cohen’s] finding that the commission motivated its recommendations for restriction through defense of an ‘American standard of living.’" - Choice
