Fiscal Year (FY) 2020, October 1, 2019 through September 30, 2020, saw the highest number of illegal border crossings since at least 1960, when the government began tracking the crossings.
Most of those apprehended (1.1 million, or 64% of the total) were individuals. Children traveling without parents of guardians, nearly 147,000, arrived in the largest numbers since 2008 when the government began tracking unaccompanied kids. The number of migrant families dropped about 48,000 from the last surge in 2019.
Though people from Mexico represented the largest portion of migrants, agents detained people from more than 160 countries in Asia, Africa and Latin America.
