The net increase in the number of employed working-age adults in North Carolina has gone entirely to legal and illegal immigrants since 2000, according to an analysis of government data conducted by the Center for Immigration Studies.

CIS, in recent weeks, has been publishing studies showing the negative impact of immigration on work force participation among “natives” in certain states and across the country.

According to CIS the two major conclusions from their study include:
