All of the net gains in jobs since 2007 have gone to legal and illegal immigrants which means that fewer U.S.-born Americans were working in December 2014 than were at the end of 2007

With total employment running at about 147 million, every one percentage point gain in the immigrant employment share translates to as many as 1.47 million fewer U.S.-born workers. From February 2009 - Obama’s first full month in office - to December 2014 the immigrant share of total employment rose from 14.97% to 16.91% - a gain of 1.94 percentage points. This implies that as many as 2.85 million (1.94 multiplied by 1.47 million) U.S.-born Americans may have lost jobs due to immigration. From January 2009 to December 2014, foreign-born employment rose by 3.286 million, or by 15.2%.
