During President Barack Obama's administration, more than 2.5 million undocumented immigrants were deported from the United States between 2009 and 2015

. The administration set record numbers of deportations in several years, including about 438,421 in 2013 and nearly 400,000 in 2011

. In fiscal year 2014 alone, approximately 414,481 unauthorized immigrants were deported

. Obama's administration focused deportation efforts primarily on convicted criminals, recent border crossers, and those deemed threats to public safety, with 91% of removals in 2015 being individuals with prior criminal convictions

. This approach led to a significant increase in deportations of criminal aliens compared to previous administrations

. In summary, under Obama, the total number of deportations exceeded 2.5 million, making it the highest in U.S. history for any president up to that point
