The mission of the Center for the Study of Immigrant Integration (CSII) is to remake the narrative for understanding, and to shape the dialogue, on immigrant integration in America.

Our intent is to identify and evaluate the mutual benefits of immigrant integration for the native-born and for immigrants, and to study the pace of the ongoing transformation in different locations, not only in the past and present but projected into the future.

 CSII's research brings together three emphases:

  • scholarship that draws on academic theory and rigorous research;
  • data that provides information structured to highlight the process of immigrant integration over time;
  • and engagement that seeks to create new dialogues with government, community organizers, business and civic leaders, immigrants and the voting public.


What is immigrant integration?

CSII defines immigrant integration as improved economic mobility for, enhanced civic participation by, and receiving society openness to immigrants. CSII identifies and evaluates the mutual benefits for the native born and immigrants and study the pace of change in different locations, not only in the past and present but the future as well.
