Immigrant groups in the United States cluster in specific business sectors. For example, Koreans are 34 times more concentrated in self-employment for dry cleaning than other immigrant groups, and Gujarati-speaking Indians are 84 times more concentrated in managing motels. We quantify that smaller and more socially isolated ethnic groups display higher rates of entrepreneurial concentration. This is consistent with a model of social interactions where nonwork relationships facilitate the acquisition of sector-specific skills and result in occupational stratification along ethnic lines via concentrated entrepreneurship.
