Border Bombshell: 8 Million New Arrivals Under Biden

The immigration surge of the past few years has been the largest in U.S. history, surpassing the great immigration boom of the late 1800s and early 1900s, according to a New York Times analysis of government data.

Annual net migration — the number of people coming to the country minus the number leaving — averaged 2.4 million people from 2021 to 2023, according to the Congressional Budget Office. Total net migration during the Biden administration is likely to exceed eight million people.

That’s a faster pace of arrivals than during any other period on record, including the peak years of Ellis Island traffic, when millions of Europeans came to the United States. Even after taking into account today’s larger U.S. population, the recent surge is the most rapid since at least 1850.

The numbers in the Times analysis include both legal and illegal immigration. About 60 percent of immigrants who have entered the country since 2021 have done so without legal authorization, according to a Goldman Sachs report based on government data.

The combined increases of legal and illegal immigration have caused the share of the U.S. population born in another country to reach a new high, 15.2 percent in 2023, up from 13.6 percent in 2020. The previous high was 14.8 percent, in 1890.

Several factors caused the surge, starting with President Biden’s welcoming immigration policy during his first three years in office. Offended by Donald J. Trump’s harsh policies — including the separation of families at the border — Mr. Biden and other Democrats promised a different approach. “We’re a nation that says, ‘If you want to flee, and you’re fleeing oppression, you should come,’” Mr. Biden said during his 2020 presidential campaign.

After taking office, his administration loosened the rules on asylum and other immigration policies, making it easier for people to enter the United States. Some have received temporary legal status while their cases wend through backlogged immigration courts. Others have remained without legal permission.
