Obama administration simply changed the definition of deportations. It started counting the people who were turned away at the border as deportations, which previous administrations did not do. Hence, his deporter in chief tag is false & the LA times published the article below to placate the immigration activists who were angry with Obama based on these “high”(false) numbers.

But the portrait of a steadily increasing number of deportations rests on statistics that conceal almost as much as they disclose. A closer examination shows that immigrants living illegally in most of the continental U.S. are less likely to be deported today than before Obama came to office, according to immigration data.
Expulsions of people who are settled and working in the United States have fallen steadily since his first year in office, and are down more than 40% since 2009.
On the other side of the ledger, the number of people deported at or near the border has gone up — primarily as a result of changing who gets counted in the U.S. Immigration and Customs Enforcement agency’s deportation statistics.
The vast majority of those border crossers would not have been treated as formal deportations under most previous administrations. If all removals were tallied, the total sent back to Mexico each year would have been far higher under those previous administrations than it is now.
Until recent years, most people caught illegally crossing the southern border were simply bused back into Mexico in what officials called "voluntary returns," but which critics derisively termed “catch and release.” Those removals, which during the 1990s reached more 1 million a year, were not counted in Immigration and Customs Enforcement’s deportation statistics.
Deportations of people apprehended in the interior of the U.S., which the immigration agency defines as more than 100 miles from the border, dropped from 237,941 in Obama’s first year to 133,551 in 2013, according to immigration data.
