Data from the State Department's Refugee Processing Center reveals that more than 3 million refugees have arrived in the U.S. since 1975, with more than 40,000 being admitted so far in 2016. Pew Research Center staffer Ruth Igielnik takes a look at the origins of these refugees; the largest numbers for this year are coming from Burma (Myanmar), the Democratic Republic of the Congo and Somalia.
Global conflict has historically played a role in the numbers of refugees who come to the country, such genocide in Kosovo in the 1990s.
In recent years, overall refugee volume is hovering at median levels historically. The number of refugees experienced a dramatic dip following the passing of the Patriot Act in 2001 – fewer than 30,000 refugees were let into the U.S. each year in 2002 and 2003, down 60% from the pre-9/11 level in 2001
