A new influx of unaccompanied children are arriving, once again from El Salvador, Guatemala, and Honduras.
In October and November, more than 10,500 children crossed the U.S.-Mexico border by themselves, the vast majority from El Salvador, Guatemala and Honduras, according to U.S. government data analyzed by the Migration Policy Institute, a non-partisan think tank. That’s a 106 percent increase over the same period year, reflecting a steady increase that began in March.
In the past two years there has been quite a bit of debate about causation, which remain mostly unanswered because you can't explain variation (changes in the numbers) with a constant (violence and insecurity).
One possibility the article suggests is how the smuggling of unaccompanied children has become a booming illegal business. Some of the increase could there be attributed to more active recruitment by human smugglers making promises.
You may have noticed that in the past two years we've seen pretty minimal response rather than reactive. There is this massive Central America aid bill floating around but it's not even always clear how it'll get to the heart of this particular matter. Because of the Paris and San Bernadino attacks, unlike in the past this issue will likely get less attention than it did before.
