The Obama administration resettled 8,858 Somali refugees in the United States last year, and nearly 43,000 during Obama's eight years, a huge number that is now raising concerns after a Somali refugee led a one-man attack spree on the campus of Ohio State.

Like Syrian refugees, there is no adequate way to check the backgrounds of the Somalis, according to the head of the Center for Immigration Studies.

The Somali refugee numbers into the U.S. from the Department of Homeland Security and State:

— 2015, 8858.

— 2014, 9,000.

— 2013, 7,608.

— 2012, 4,911.

— 2011, 3,161.

— 2010, 4,884.

— 2009, 4,189.

The Center also reviewed other data Monday and told Secrets that some 97,000 Somali refugees have been resettled in the United States since 9/11. Of those, 99.6 percent were Muslim, and 28,836 (29.7 percent) were males between the ages of 14 and 50.

In a review of the numbers he reissued after Monday's attack, CIS Executive Director Mark Krikorian said:

"We have no way of vetting people from any of the failed states of the Islamic world, whether Somalia or Libya or Yemen or Afghanistan or Iraq. The latter two actually we have more intelligence on, having ruled them for a number of years, but even that information is of limited use; we admitted two Iraqis as refugees who, we only discovered later, had been [improvised explosive device] makers back in Iraq. And the FBI fears dozens more such terrorists have been admitted as refugees.

"Oh, and we resettled nearly 9,000 Somali refugees last year."

He wrote that in a blog post last year based on the latest information available.
