Which years between 2003 and 2017 show elevated deaths in immigration detention according to academic, FOIA or advocacy compilations, and where can those datasets be accessed?
Executive summary
Between 2003 and 2017, public records and academic reviews show several years with clearly elevated numbers of deaths in U.S. Immigration and Customs Enforcement (ICE) custody, most notably around 2008–2009 and in 2016–2017; the primary sources for year-by-year counts are ICE’s FOIA release of detainee deaths and academic compilations that cross‑reference those FOIA lists and detainee death reviews (DDRs) [1] [2] [3]. Access to the raw FOIA list and the academic articles that analyzed it provides the best entry points for verifying which specific years were above the long‑term average [1] [2].
1. How “elevated” is being measured — the datasets behind the claim
The most direct dataset is ICE’s FOIA disclosure titled “List of Deaths in ICE Custody: Data from 10/01/2003 to 06/05/2017,” which is the baseline for many scholarly and advocacy counts and can be accessed through the ICE FOIA report itself [1]. Peer‑reviewed researchers then used that FOIA list and the individual detainee death reviews (DDRs) produced by ICE to build analytic datasets: for example, a 2021 case‑series and related 2011–2018 thematic analyses reconstruct deaths and circumstances by linking DDRs to the FOIA list [3] [4]. Advocacy groups and watchdogs have also compiled overlapping lists, sometimes adding post‑2017 deaths or reconciling discrepancies with media reporting [5] [6].
2. Years that stand out in the public record (2003–2017)
Several years are repeatedly highlighted as anomalous in the assembled records: the late 2000s showed a spike (reporting singles out 2008 as higher than surrounding years), and attention returns to 2016–2017 when counts increased again; multiple outlets and analyses flagged 2017 as a particularly high year for detainee deaths and concentrated media scrutiny followed those deaths [7] [8]. Academic summaries that aggregate FOIA data report totals across the entire 2003–2017 window (for example, 172 deaths reported during that span in one review), which constrains but does not erase year‑to‑year variation observed in the ICE list [2]. News analyses that parsed the FOIA list year‑by‑year also document the uptick in 2016 and 2017 relative to prior years [7].
3. Where to find and download the datasets now
Start with ICE’s FOIA report (the “List of Deaths in ICE Custody: 10/01/2003 to 06/05/2017”), which is posted in full and was used as the foundation for academic work and media analyses [1]. The peer‑reviewed articles that analyzed DDRs and FOIA counts — notably the 2021 case series and the thematic analysis of deaths in detention — are available through PubMed/PMC and include methods and references to the underlying DDRs and FOIA list used to build analytic tables [3] [4]. For advocacy compilations and independent cross‑checks, consult Human Rights Watch summaries and the ACLU/PHR/American Oversight report for post‑2017 follow‑up; these cite and reproduce relevant FOIA and DDR material when possible [5] [6].
4. Caveats, discrepancies and competing tallies
Different organizations report slightly different totals because some datasets include deaths that occurred after transfer to hospitals, some rely solely on ICE’s FOIA list while others cross‑reference media and NGO reports, and some extend the window beyond mid‑2017 [9] [4]. Academic studies typically limit their sample to dates for which DDRs were released and verified, while advocacy groups may include additional cases identified through investigative reporting or subsequent FOIA releases [2] [6]. Because of those methodological differences, the FOIA list is the canonical primary source for 2003–mid‑2017 counts but should be cross‑checked against DDRs and scholarly supplements to capture context and timing [1] [3].
5. What the records imply and the limits of the public record
The FOIA list plus scholarly DDR analyses show that deaths were not uniformly distributed across 2003–2017 and that clusters — especially in the late 2000s and again in 2016–2017 — produced alarm and follow‑up investigations; those same sources also document systemic concerns about medical care and oversight that accompany the elevated counts [1] [5] [3]. However, granular causal inference (for example, attributing a specific annual rise to a single policy change) is constrained by reporting lags, differences in counting rules, and incomplete release of DDRs for every case [2] [4]. For precise year‑by‑year tabulations, download ICE’s FOIA file first and pair it with the 2021 and thematic academic articles that document DDR linkage and coding decisions [1] [3] [4].
