"Over the 2000-2005 period, immigration levels remained very high and roughly half of new immigrant workers were illegal. This report finds that the arrival of new immigrants (legal and illegal) in a state results in a decline in employment among young native-born workers in that state. Our findings indicate that young native-born workers are being displaced in the labor market by the arrival of new immigrants."
