Since 2014, at least 56,800 migrants around the world have gone missing or been killed, according to an Associated Press report.
The big picture: The AP's number doubles the one from the UN's International Organization for Migration, which is the only official attempt to tally the toll of the world's migration crisis. And the news agency admits that its count is "still low" as a portion of migrant deaths inevitably go undiscovered or unreported.
