the author's explain:
Just how real is the “homegrown” Islamist terrorist threat? The New America Foundation and Syracuse University’s Maxwell School of Public Policy have examined the post-9/11 cases of Americans or U.S. residents convicted or charged of some form of jihadist terrorist activity, as well as the cases of those American citizens who have traveled overseas to join a terrorist group.

Probably a unique information source.
