From the summary:
Intensified violence and poverty in the Northern Triangle countries of Central America have spurred migration among youth who seek to either reunite with family or to support families who remain abroad. Policies to protect these youth would promote their holistic integration into U.S. society, enforce safety and well-being along the U.S. southern border and help strengthen the youths’ countries of origin socially, economically and politically.
U.S. Customs and Border Protection (CBP) reports that 68,541 children were apprehended at the U.S. southwest border between October 1, 2013 and September 30, 2014. Apprehension rates of unaccompanied children there from all countries in FY 2015 through March declined 45 percent compared to the same period in the year before. However, from 2009 through FY 2014, apprehensions of unaccompanied children from Northern Triangle countries Guatemala, Honduras and El Salvador increased from 3,304 to 51,705.
