In an analysis of Bureau of Labor Statistics data, CIS researchers Steven Camarota and Karen Zeigler found that between January and July, Trump has overseen an “unprecedented” 2.2 million-person decline in the nation’s total foreign-born population — 1.6 million of whom are illegal aliens.
“Analysis of the [Current Population Survey] data shows the total foreign-born population of all ages, both in and out of the labor force, declined an unprecedented 2.2 million from January to July – the largest six-month decline ever within the same year,” the researchers write

Non-citizens accounted for all of the falloff in the total foreign-born; the naturalized U.S. citizen population has actually increased some since January. [Emphasis added]
We preliminarily estimate that the illegal immigrant population declined an astonishing 1.6 million (10 percent) to 14.2 million from January to July of this year. [Emphasis added]
The analysis comes as recent jobs data showed that all employment gains in recent months are going to native-born Americans rather than foreign-born workers.
“While employers may be unhappy with a decline in illegal immigrant workers, reducing the supply of labor is likely to be very helpful to less-educated U.S.-born and legal-immigrant workers, whose wages may rise as a result,” CIS researchers note:
Further, a tighter labor market and higher wages may help to draw back into jobs the near-record number of working-age American men without a college degree not in the labor force.
