Study: U.S. took in two immigrants for every net job created over the last 15 years

The Center for Immigration Studies has released a report that says roughly two immigrants have arrived in the United States over the last 15 years for every net job that was created in that period of time.

CIS said that according to government data, 18 million immigrants entered the U.S. from 2000 until the end of 2014. That includes both legal and illegal immigrants.

In that same period of time, just 9.3 million net jobs were created, CIS said.

The report also noted that the domestic population age 16 and older grew by 25.2 million. That means more than 40 million people became of working age from 2000 to 2015, and competed for just 9.3 million net jobs.

"Because job growth has not come close to matching immigration and population growth, the share of Americans in the labor force has declined dramatically — a clear indication there is no labor shortage," the report said.

"Despite this, Congress is considering proposals to increase legal immigration even further; and during the last Congress the Senate actually passed the Schumer-Rubio bill, which would have doubled legal immigration and legalized illegal immigrants," it added. "Congress's disregard for the absorption capacity of the U.S. labor market has profound consequences for American workers."

CIS has opposed Democratic efforts to expand legal immigration, as well as President Barack Obama's plan to excuse millions of illegal immigrants from deportation. The group has said numbers such as the ones in its latest report show there's no need to flood the U.S. market with more cheap, foreign labor.

According to CIS, somewhere between two-thirds and three-fourths of the 18 million immigrants were legal, and about 90 percent were potential workers aged 16 and up.

The report said native-born Americans made up 77 percent of the workforce in 2000, but less than 72 percent by the end of 2014.
