The figures also show that deportations of criminal immigrants have dropped to the lowest numbers since President Barack Obama took office in 2009, despite his pledge to focus on finding and deporting criminals living in the country illegally.
The overall total of 231,000 deportations generally does not include Mexicans who were caught at the border and quickly returned home by the US Border Patrol. The figure does include roughly 136,700 convicted criminals deported in the last 12 months. Total deportations dropped 42 percent since 2012.
And they come as Obama carries out his pledge from before his 2012 re-election to narrowly focus enforcement and slow deportations after more than a decade of rising figures.
The biggest surprise in the figures was the decline in criminal deportations. The Homeland Security Department secretary, Jeh Johnson, last year directed immigration authorities anew to focus on finding and deporting immigrants who pose a national security or public safety threat, those who have serious criminal records or those who recently crossed the Mexican border.
