An analysis of data from the past decade and a half show that in the 25 largest metropolitan areas, immigration and economic growth go hand in hand. That’s easily understandable: Economic growth and labor force growth are closely connected, and immigrants are likely to move to areas where there are jobs, and not to areas where there are not.

Between 1990 and 2006, the metropolitan areas with the fastest economic growth were also the areas with the greatest increase in immigrant share of the labor force. The economies of Phoenix; Houston, TX and Dallas ,TX saw the fastest growth in immigrant share of labor force, while all showed well above average economic growth in these years and Phoenix experienced the fastest growth of all metro areas. By contrast, Cleveland, Pittsburgh and Detroit metro areas experienced the slowest economic growth and among the smallest increases in immigrant share of labor force. compare with the economy growth of Austin, TX.

Economic growth does not guarantee, however, that pay and other conditions of employment improve significantly for all workers. The challenge is to make sure that immigrants and U.S.-born workers struggling in low-wage jobs share in the benefits of economic growth.
