The number of immigrants monitored on ICE's electronic monitoring program known as ISAP or Alternatives to Detention continued its march upward to about 240,000. The vast majority of these, nearly 187,000, were monitored using a smartphone app called SmartLINK, while GPS ankle monitor use actually declined to less than 23,000, the smallest since 2020 when TRAC began tracking these data.

Importantly, these data show that the number of immigrants in detention and the number of immigrants monitored on ICE's Alternatives to Detention (ATD) program can increase at the same time. Although ICE calls its program "Alternatives" to Detention, the agency makes clear on its website that its ATD program is "not a substitute for detention, but allows ICE to exercise increased supervision over a portion of those who are not detained." Thus, growth in ATD supervision does not necessarily correspond to a decline in immigrant detention.

The Transactional Research Access Clearinghouse (TRAC) a research organization at Syracuse University created 'Quick Facts' tools to provide a user-friendly way to see the most updated data available on immigrant detention and the immigration courts. The tools include easy-to-understand data in context and provide quotable descriptions.

Highlights from data updated today on the immigration detention system provided by show that:

• Immigration and Customs Enforcement held 22,281 in ICE detention according to data current as of May 7, 2022.

• 16,034 out of 22,281—or 72.0%—held in ICE detention have no criminal record, according to data current as of May 7, 2022. Many more have only minor offenses, including traffic violations.
