New illegal immigrants accounted for 56 percent of the increase in employed workers in the United States in the five years after 2000, and competition from these immigrants contributed to a sharp decline in employment of teenage and young adult Americans, according to a labor market study released yesterday. The survey found that in the five-year period, foreign-born workers, including both legal and illegal immigrants, made up 86 percent of the net increase in the total number of employed workers, the highest share for immigrants ever recorded in this country.
