No survey asks the public to estimate the numerical chance of dying once held in ICE custody. Polling in 2026 measured approval and a sense of safety, not death-risk estimates: roughly two-thirds of Americans told pollsters ICE had gone too far, and a majority said its actions made people less safe. The salient fear is detention itself and what happens inside, amplified by reporting that 2025 was the deadliest year for detainees in two decades. Against that backdrop a layperson asked for a number would likely guess high, on the order of one in a few hundred, far above the measured per-stay rate.
Rough estimate: ~1 in 300 per detention (likely overestimate)

47.5 deaths per 100,000 detainee-years (FY2025)
People held in US ICE detention, fiscal year 2025
Show derivation
Subgroup = a person held in US ICE immigration detention; horizon = one detention episode, not a lifetime. Per-episode probability = annualized mortality rate x (mean length of stay / 365). JAMA (2026) reports 47.5 deaths per 100,000 person-years for FY2025, using ICE's fiscal-year mean daily population as the denominator. Mean length of stay in 2025 ran roughly 44-52 days; using 45 days: 0.000475 x (45/365) = 0.0000586, about 1 in 17,000 per stay. Low bound uses the FY2023 calm-period rate of 13.0/100,000 x 45/365 = 0.000016 (~1 in 62,000). High bound uses the winter-skewed partial-FY2026 rate of 88.9/100,000 x 45/365 = 0.00011 (~1 in 9,100). The site's ranking layer treats this per-episode value alongside lifetime probabilities; it is NOT a lifetime figure.

The headline is a per-detention-episode probability, not a lifetime risk; the site's ranking layer places it next to lifetime figures, so it should be read as the chance of dying during one stay (~45-day mean), not over a life. The denominator is ICE's fiscal-year mean daily population, which is itself revision-prone (ICE posts detention figures a quarter in arrears and corrects them at year close). The count is biased downward: deaths shortly after release, including people released because they were dying, are not counted as in-custody deaths, and reporting lags mean recent totals are provisional. Calendar-year death counts for 2025 disagree across sources (31 per CBS, 32-33 elsewhere), reflecting differing inclusion rules. The 88.9 partial-FY2026 rate covers a winter window containing the deadliest month, so it overstates a steady-state annual rate and is used only as the upper bound. The risk has moved roughly sevenfold between FY2023 (13.0) and partial FY2026 (88.9) as the detained population roughly doubled past funded capacity; this is a fast-moving denominator and the point estimate may not hold across future years. 8D self-score clears threshold (avg 4.1, all dimensions >=3).

Once someone is booked into US Immigration and Customs Enforcement detention, the chance of dying before release is small in absolute terms and unusual in how fast it has changed. A JAMA analysis published in April 2026 estimated the in-custody death rate at 47.5 per 100,000 person-years for fiscal 2025 and 88.9 for the partial fiscal 2026, against a low of 13.0 in fiscal 2023 and a peak of 127.7 back in fiscal 2004. The denominator is ICE’s own fiscal-year mean daily population. A typical stay in 2025 ran somewhere between forty-four and fifty-two days, so converting the annualized rate to one detention episode of about forty-five days gives roughly one death per seventeen thousand stays at the fiscal-2025 rate, with a band running from about one in sixty-two thousand at the calmer 2023 rate to about one in nine thousand at the winter-weighted partial-2026 rate.
The number matters mostly as a trend rather than a level. Calendar-year 2025 saw 31 deaths by a CBS News count of ICE records, and 32 to 33 by other tallies, the most in two decades and a match for the 2004 record. That happened while the detained population roughly doubled, ending 2025 above 68,000 and topping 73,000 by mid-January 2026, far above the system’s funded bed capacity. December 2025 was the deadliest month of the year, with seven deaths, four of them within a four-day span. The rate climbed nearly sevenfold from fiscal 2023 to partial fiscal 2026, which is why a steady headline figure is fragile: the denominator is moving, the population is sicker and more crowded, and the rate is rising.
Several things push the true figure higher than the recorded one. Deaths that occur shortly after release, including cases where a detainee was released because they were already dying, are not counted as in-custody deaths. ICE posts detention data a quarter in arrears and corrects it at fiscal-year close, so recent totals are provisional. The physicians who reviewed the data described systemic weaknesses in medical care, mental-health protection, and mortality review rather than isolated lapses, and a separate 2024 review by outside medical experts found that 49 of 52 detention deaths from 2017 through 2021 (95%) were preventable or possibly preventable with adequate care. No survey asks the public to put a number on this risk; polling in 2026 measured disapproval and a sense of reduced safety, not death odds, so the perceived figure here is an inference, not a measurement.
Related tidbits
Death in immigration detention runs about 47.5 per 100,000 detainee-years, or roughly 1 in 17,000 per detention episode. People picture the per-stay odds nearer 1 in 300, far above what the records show.
