Historically, the United States has led the world in refugee admissions, having taken in more than 3 million of the 4 million refugees resettled worldwide since the law’s adoption.

But in 2017, the United States took in 33,000 refugees. That figure marks a sharp decline from the roughly 97,000 refugees resettled in 2016 and the lowest amount since the terrorist attacks of Sept. 11, 2001, when the government suspended refugee admissions for three months.

The rest of the world admitted about twice as many refugees last year, at 69,000.
