A bar chart showing the number of arrests at the Southwest border, per month from October 2015 to October 2025, highlighting when Obama, Trump and Biden were president. In 2015 and 2016, monthly arrests are about 50,000 under Obama, while a spike in 2019 under Trump nears 150,000 and then declines. A sharp increase comes in mid-2020 after the Covid Title 42 policy begins, and from 2021 to 2024 under Biden, it is mostly over 150,000 per month. Arrests fall sharply in late 2023, and under Trump's second presidency fall to well below 50,000 per month.
