Since taking office in January 2025, President Donald Trump's administration has overseen a reduction of approximately 1.6 million illegal immigrants in the United States, according to estimates from the Center for Immigration Studies and statements by Secretary of Homeland Security Kristi Noem. Noem reported that these individuals have voluntarily left the country during Trump's tenure. The administration is also noted for increasing deportations, with reports indicating that over 1,400 illegal aliens are being deported daily, positioning Trump to surpass former President Barack Obama’s deportation record. Additionally, the Trump administration has made efforts to reduce the deportation court backlog for the first time in nearly two decades. However, some sources suggest the immigrant population may have fallen by as much as 2.2 million over six months due to heightened enforcement measures, including deportations and visa revocations. Critics have highlighted concerns about the government ceasing to collect certain immigration data amid these changes.
