In late October, President Donald Trump lifted a temporary ban on most refugee admissions, a move that should have cleared the way for more people fleeing persecution and violence to come to the United States.

Instead, the number of refugees admitted to the country has plummeted. In the five weeks after the ban was lifted, 40 percent fewer people were allowed in than in the last five weeks it was in place, according to an analysis of State Department data. That plunge has gone almost unnoticed.

As he lifted the ban, Trump instituted new rules for tougher vetting of applicants and also effectively halted, at least for now, the entry of refugees from 11 countries deemed as high risk. The latter move has contributed significantly to the precipitous drop in the number of refugees being admitted.
