The Census Bureau has released a working paper written by me and my colleagues entitled The Size, Place of Birth, and Geographic Distribution of the Foreign-Born Population in the United States: 1960 to 2010.
This working paper summarizes many of the changes that have occurred over the last 50 years, as the foreign-born population has shifted from an older, predominantly European population settled in the Northeast and Midwest to a younger, predominantly Latin American and Asian population settled in the West and South.
The paper also includes several graphs and a set of maps — one for each decade from 1960 to 2010 — dramatically illustrating the change in size and distribution of the foreign-born population in the United States through time.
