Since Congress revamped the immigration enforcement system in 1996, the United States has formally deported more than 4.6 million noncitizens, with about 3.7 million of these occurring since the creation of the Department of Homeland Security in 2003, according to a report from the Migration Policy Institute. The report, which was supported by MacArthur, offers a profile of deportees and examines how removal trends changed during and between the Bush and Obama administrations as well as how closely the deportations adhere to current DHS enforcement priorities.
