(CNN) The United States admitted 22,491 refugees in the last fiscal year -- one of the lowest amounts on record.

The admissions count for the 2018 fiscal year, which ended on September 30, was less than half the number of refugees admitted in FY 2017 (53,716) and about one-quarter of the number of people admitted in FY 2016 (84,994). According to State Department records going back to 1975, the only year that the US admitted fewer refugees was 1977.

A State Department spokesperson said the reduced number of admissions "was consistent with operational capacity to implement new screening and vetting procedures following Executive Order 13780, Protecting the Nation from Foreign Terrorist Entry Into the United States."

That executive order -- the second iteration of the President's "travel ban" -- was issued by President Donald Trump in March 2017 and the Supreme Court allowed it to go into partial effect in June 2017. It barred people from Iran, Libya, Somalia, Sudan, Syria and Yemen from entering the US for 90 days unless they could prove a "bona fide relationship with any person or entity in the United States."

According to the numbers released Tuesday, the US admitted less than 500 refugees overall from all six of the nations restricted by the executive order. The majority of refugees admitted were from the Democratic Republic of Congo (7,878), Burma (3,555), Ukraine (2,635) and Bhutan (2,228).
