While ICE detainer usage is up since the FY 2015-2016 period when ICE's Priority Enforcement Program (PEP) was in place, ICE's current use of detainers is well below the levels existing during the Secure Communities era under President Obama. On a fiscal year basis, for example, FY 2017 detainer usage was 48 percent lower than five years ago.

Although the accuracy of ICE records on detainer refusals is questionable, these records indicate that the refusal rate during the March 2017 - November 2017 period was up 32.1 percent over the same nine month period in 2016. However, recorded refusals remain quite low. Only 5.3 percent of detainers ICE prepared are recorded by the agency as being refused by the LEA, while the rate in 2016 was a refusal rate of just 4.0 percent.
