Immigration and county employment growth

Prior literature has found that immigrants have no effect on the wages and employment of natives. However, this literature has not accounted for the possibility that immigrants contribute to employment growth in the areas where they locate. Research on internal migration has found that internal migrants contribute to local area employment growth. In this paper I compare the effects of natives and immigrants on county employment. Results show that the overall immigrant population contributes more to increases in employment than the overall native population. Recent immigrants and recent internal in-movers have similar effects on employment growth. The net contribution of immigrants to employment growth is confined to nonmanufacturing employment.
