(originally published 9/27/13) The foreign-born population in America is over 13 percent of the total population, the largest share of immigrants since the 1920s. Over 40 million immigrants—documented and undocumented, young and old—live and work in towns and metropolitan areas throughout the country. In this podcast, Audrey Singer, a senior fellow in the Metropolitan Policy Program, puts today's immigrant population into historical context, explains where they live now and how they contribute to their communities, and looks ahead to the prospect for comprehensive immigration reform at the federal and local levels. Singer, an expert on immigrants and demographic change, says that one important issue on which emphasis should be placed is the social, economic, civic and political integration of immigrants into the places where they live.
