Currently, over 15 percent of the U.S. workforce is foreign born, with those from Latin America and Asia accounting for more than three-fourths of the immigrant population. The large share of immigrant workers in the United States and other developed economies has potentially important implications for native workers and for the labor market performance of those economies.


  • What are the costs and benefits to the receiving countries and to the countries of origin of immigration?
  • Does immigration depress wages or wage growth?
  • Does an influx of immigration increase unemployment among native workers?
  • Is there a relationship between expanded trade and immigration?
