Immigration has been on the forefront of American policy issues for sometime now, and the foreign population in the United States is approaching historic levels. In March 2010, the Brookings Institution's Audrey Singer and John Mollenfkopf offered a presentation that examines this transformation. The presentation is focused on the "numerous affects of the country's changing demographics, from shifts in the job market to how second-generation immigrants will socially incorporate themselves into American society." Visitors will note that the presentation contains 31 separate slides including helpful graphs, charts, and policy suggestions for the future. One of Mollenfkopf and Singer's suggestions include "eliminating political gridlock on the federal level to help push through comprehensive reform."
