The United States is an immigrant country. Germany is not. This volume shatters this widely held myth and reveals the remarkable similarities (as well as the differences) between the two countries. Essays by leading German and American historians and demographers describe how these two countries have come to have the largest number of immigrants among the advanced industrial countries, how their conceptions of citizenship and nationality differ, and how their ethnic compositions are likely to be transformed in the next century as a consequence of migration, fertility trends, citizenship and naturalization laws, and public attitudes.
