For months now, the words “we must do something about the border” have been thrown about in the United States—as though the border were a leaky roof or broken window that could be quickly repaired and made new again. Listen closely, however, and it becomes apparent that many politicians mean something different altogether. To them, “doing something about the border” means preventing people from accessing border crossings and preventing them from obtaining asylum or other legal means of entry.

The impact on those real people easily gets lost in budget talks and political squabbling. Understanding who is coming to the border can help us make better decisions about what actually needs to be done to create a functioning migration system.
