Using data from the 1960–2000 decennial censuses, the study shows that immigration is associated with lower in-migration rates, higher out-migration rates, and a decline in the growth rate of the native workforce. The native migration response attenuates the measured impact of immigration on wages in a local labor market by 40 to 60 percent, depending on whether the labor market is defined at the state or metropolitan area level.
