From The New York Times:
Illegal crossings at the U.S.-Mexico border are down to their lowest level in decades. Once-crowded migrant shelters are empty. Instead of heading north, people stranded in Mexico are starting to return home in bigger numbers.
The border is almost unrecognizable from just a couple of years ago, when hundreds of thousands of people from around the world were crossing into the United States every month in scenes of chaos and upheaval. If that trend holds for a full year, migrant apprehensions in the United States could fall to levels unseen since around 1967, according to Adam Isacson, a migration expert at the Washington Office on Latin America, a nongovernmental organization.
