Fact check: How many undocumented immigrants have gone missing in the US since 2020?

1. Why no single number exists—and what officials admit

Government oversight reviews and reporting show that official systems lack complete data on missing migrants, which explains why a single post-2020 tally is unavailable. The U.S. Border Patrol’s Missing Migrant Program has improved procedures and records but explicitly still has incomplete information on migrant deaths and disappearances; the Government Accountability Office documented steps taken and recommended further coordination and guidance revisions to close data gaps ^[2]. This institutional shortfall means federal databases cannot currently produce a comprehensive count of undocumented people who have gone missing nationwide since 2020, and reporting remains piecemeal across agencies and civil-society groups.

2. What journalism and advocacy flag as the largest visible problem

Investigative reporting and advocacy groups emphasize thousands of children and migrants disappearing from care or oversight, highlighting concrete clusters rather than national totals. A February 2024 article documented thousands of migrant children who disappeared from sponsors’ homes, noting over 6,300 calls to the Office of Refugee Resettlement’s hotline from 2018–2023, and concentrated local spikes such as 35 cases in one Virginia town ^[1]. These figures underscore an operational reality: tracking gaps are most visible in child welfare and sponsor-placement systems, where missing-case counts are substantial but not aggregated into a bigger undocumented-immigrant missing-persons total.

3. Advocacy reports contextualize disappearances as policy-driven

Civil-society reports argue that U.S. border enforcement tactics and migration management practices contribute to a broader crisis of disappearance in the borderlands, though these studies typically document patterns rather than a U.S.-wide tally since 2020. Collaborative reports by border-rights organizations describe mass disappearance and deaths tied to policing and enforcement policies, presenting qualitative and regional evidence of disappearances and fatalities but stopping short of producing an all-encompassing numeric total for missing undocumented people within the U.S. ^[3]. These reports frame disappearance as both a humanitarian and a policy problem, urging systemic change while documenting substantial but dispersed cases.

4. Hispanic and migrant children appear disproportionately in missing-children counts

Analyses of missing-children databases highlight that Hispanic children account for a large share of reported missing cases, which intersects with undocumented migration issues but does not translate directly into a count of missing undocumented adults. Noticias Telemundo’s April 2024 analysis found Hispanic children represented a significant portion of missing-child reports between 2003 and 2023, citing socioeconomic drivers and online vulnerabilities ^[5]. These trends show where disappearances cluster demographically and substantiate advocacy concerns about protections for migrant and Hispanic youth, even as the sources do not enumerate all undocumented persons missing post-2020.

5. Recent reporting points to operational chaos and untracked detainees

More recent journalism highlights instances where detainees or migrants “drop off the grid” after transfers, detentions, or deportations, but such accounts focus on facility-level failures rather than producing a national missing-persons total. Articles from 2025 document chaotic conditions in certain detention sites and note hundreds of detainees could not be located after transfers, illustrating accountability and transparency shortfalls in detention and transport systems ^[6]. These case-based findings reinforce the systemic data problems flagged by oversight bodies and advocate groups, showing concrete instances of people becoming untraceable in administrative processes.

6. Conflicting claims and the danger of single-source figures

Public statements and some commentators offer striking numbers—such as claims about tens of thousands of missing children—yet those figures are often unsupported by pooled official datasets and should be treated cautiously. For example, a high-profile figure of nearly 25,000 “missing illegal immigrant children” has circulated in media commentary, but associated reporting acknowledges a lack of comprehensive evidence tying such counts to an official, aggregated national registry ^[7]. The discrepancy between bold public claims and incomplete administrative records illustrates why relying on a single-source number would be misleading.

7. Bottom line: what we can reliably say and what remains unknown

Based on the reviewed materials, the reliable conclusions are clear: thousands of migrant children and numerous detainees or migrants have been documented as missing or unaccounted-for in various contexts since 2018–2025, and federal reviewers acknowledge persistent data gaps that prevent producing a definitive count of undocumented immigrants missing since 2020 ^{[1] [2] [6] [3]}. What remains unknown—and what policymakers, journalists, and advocates continue to seek—is a validated, single national total that reconciles child-welfare reports, law enforcement records, detention transfers, and cross-border disappearance data into one authoritative figure.
