The number of migrants apprehended at the U.S.-Mexico border reached the highest monthly total in 15 years, with more than 170,000 crossings recorded in March, according to preliminary Customs and Border Protection (CBP) data.
The numbers, obtained by The Washington Post and The New York Times on Friday, showed that the number of recorded crossings in March is up from 78,000 recorded in January, and is the highest recorded since 2006.
In terms of unaccompanied minors, more than 18,500 were detained in March, a 60 percent increase from the previous record of 11,494 in May 2019, according to data reviewed by NBC News.

While President Biden said in a press conference last week that the influx of migrants in recent months is consistent with patterns that happen “every single, solitary year” in the winter months, the Post reported Friday that the largest two-month increase in 2019 was 45,000 migrants.
The number of migrants arriving in March 2021 increased by more than 90,000 since January.
The all-time record for monthly border crossings was set in March 2001, when CBP detained nearly 173,000 migrants at the border, NBC reported.
The Hill has reached out to CBP for additional information on the data.
The Biden administration has struggled to keep up with the rising number of migrants, particularly unaccompanied children at the border, with hundreds of minors being kept in CBP facilities for longer than the legally allowed 72 hours as they await bed space at emergency shelters run by the Department of Health and Human Services.
As of late last week, the U.S. was in custody of at least 15,000 migrant children.
