What It Is
Founded in 1951 as the Provisional Intergovernmental Committee for the Movement of Migrants from Europe, IOM joined the UN system in 2016 as a 'related organization' — neither a nor a programme. It runs migration assistance, return-and-reintegration programmes, counter-trafficking efforts, and resettlement support across 175 member states. IOM is the for the coordinating implementation of the 2018 . It also publishes the Missing Migrants Project tracking deaths along migration routes.
Funding and Operations
Funding is overwhelmingly project-based and earmarked — making IOM sensitive to donor priorities and limiting its capacity for long-term strategic work. Roughly 97% of IOM's budget is voluntary contributions tied to specific projects, with only a small core funded by assessed contributions. This structural feature means IOM's operational footprint follows where donors choose to fund — heavy presence in conflict-affected countries and major migration corridors, lighter presence in less-funded contexts.
IOM and UNHCR
IOM operates in close partnership with , which handles refugees specifically. The : UNHCR has the international protection for refugees under the ; IOM handles broader migration including labor migration, returnees, internally displaced persons (sometimes), and trafficking victims. In practice the two agencies coordinate on mixed migration flows where refugees and economic migrants travel together.
Key Operational Areas
- Migration health: medical screening, vaccination, mental-health support for migrants.
- Counter-trafficking: identification of victims, referral to services, support for prosecution of traffickers.
- Return and reintegration: assisted voluntary return programs for migrants in transit or destination countries.
- Emergency response: humanitarian assistance during migration crises (Mediterranean, Central American corridors, Sudan-Chad, Bangladesh-Myanmar).
- Data and research: the Displacement Tracking Matrix is the leading global source on IDP and migrant population data.
Common Misconceptions
IOM is sometimes confused with UNHCR. The agencies are different: UNHCR's mandate is refugee protection; IOM's mandate is migration more broadly, including non-refugee migrants. The two are partners, not the same organization.
Another misconception is that IOM has independent legal authority over migrant status. It does not — individual states retain control of admission, , and citizenship decisions; IOM advises and assists but does not adjudicate.
Real-World Examples
2024 Sudan crisis response: IOM has coordinated the response to over 10 million people displaced by the Sudan civil war, working with regional governments on cross-border movement and humanitarian access. Mediterranean migration tracking: IOM's Missing Migrants Project has documented over 60,000 deaths along migration routes since 2014, becoming the authoritative public dataset. 2026 Director-General election: Amy Pope (US) was elected Director-General in 2023, succeeding António Vitorino — the first US national to hold the post.
Example
IOM's Missing Migrants Project recorded over 8,500 deaths on migration routes worldwide in 2023 — its highest annual total since tracking began in 2014.
