In fiscal year 2013 – Oct. 1, 2012 to Sept. 30, 2013 – 82 percent of the 47,000 children age 17 and under apprehended on the border were unaccompanied. Between FY 2009 and FY 2013, the number of apprehended unaccompanied children doubled. That number is on track to double again by the end of FY 2014.
The absolute number of children being apprehended at the border is similar to that of the early-to-mid-2000s, according to the Bipartisan Policy Center. But as a percentage of all apprehensions, the number has been rising. That figure ranged from 8 to 10 percent before the recession, but went up to 11 percent in FY 2013.
