The Residential Segregation of Immigrants in the United States from 1850 to 1940

We provide the first estimates of immigrant residential segregation between 1850 and 1940 that cover the entire United States and are consistent across time and space. To do so, we adapt the Logan-Parman method to immigrants by measuring segregation based on the nativity of the next-door neighbor. In addition to providing a consistent measure of segregation, we also document new patterns such as high levels of segregation in rural areas, in small factory towns and for non-European sources. Early twentieth-century immigrants spatially assimilated at a slow rate, leaving immigrants' lived experience distinct from natives for decades after arrival.
