As momentum grows for immigration reform, Audie Cornish takes a look back in time at another moment when the country was grappling with its immigrant population. In the early 1900s, the Dillingham Commission was mandated by Congress to undertake a massive study of immigrants. We take a look at the 1911 report with Senate Associate Historian Betty Koed. Its conclusions led the country to prioritize certain immigrants over others. We explore how those findings still reverberate today with Richard Alba, a professor of sociology who has spent decades studying the immigrant experience.
