Foreign-Born Population

1850-2010

About the Project

At all points in its history, a significant proportion of the population of the United States had been born in other countries and regions. This being the case, American history can never be understood by just looking within its borders. The culture and politics of the US have always been profoundly shaped by the material and emotional ties many of its residents have had to the places where they were born. This map will allow you to begin to explore those connections at the basic level of demographic statistics.
