Refugee data: definitions, statistics and sources
Start here for what the core terms mean, what the current numbers are, and which primary datasets to cite.
TL;DR
A refugee is someone who has crossed an international border and cannot return owing to a well-founded fear of persecution, as defined by the 1951 Refugee Convention. Someone displaced inside their own country is an internally displaced person instead. Global forced displacement is reported in the range of 120 to No current figure people, of which refugees are roughly a third and internally displaced people the largest share. The primary statistical sources are UNHCR Refugee Data Finder, IOM Displacement Tracking Matrix, and IDMC GRID, and most of their datasets are free to download and reuse with attribution.
What the core terms mean
Almost every apparent contradiction in displacement statistics traces back to a category boundary. The four terms below determine which agency responds, which legal protections apply, and which dataset a person appears in.
Refugee
A person who has crossed an international border and cannot return home owing to a well-founded fear of persecution on grounds of race, religion, nationality, political opinion, or membership of a particular social group. The status comes from the 1951 Refugee Convention and its 1967 Protocol, and UNHCR holds the global mandate.
Refugee definition, explainedAsylum seeker
Someone who has applied for international protection but whose claim has not yet been decided. Asylum seekers are counted separately from recognised refugees in every major dataset, which is a common source of mismatched totals.
Asylum seeker vs refugeeInternally displaced person (IDP)
A person forced to flee within the borders of their own country. IDPs fall outside the Refugee Convention and remain under national jurisdiction, so they are tracked by IDMC and IOM DTM rather than through refugee registration.
What is an internally displaced person?Stateless person
A person not recognised as a national by any state under the operation of its law. Statelessness can overlap with displacement but is a separate legal category with its own reporting series.
What is statelessness?Definitions summarise the 1951 Refugee Convention, the Guiding Principles on Internal Displacement, and the 1954 Convention relating to the Status of Stateless Persons. For the wider vocabulary, see the displacement glossary and the refugees versus IDPs comparison.
Current statistics
Headline totals move for two different reasons: real displacement events, and revisions to registration coverage. Each page below states which of the two is driving a change, and links the underlying series so the figure can be checked rather than taken on trust.

Methodology note: figures across this site are compiled from the agencies above without adjustment, and are attributed at the point of use. Mid-year releases are provisional and frequently revised upward as registration catches up with arrivals, so a rising series does not always indicate rising displacement.

Displacement glossaryFrequently asked questions
What is the definition of a refugee?
Under the 1951 Refugee Convention, a refugee is a person who is outside their country of nationality and unable or unwilling to return owing to a well-founded fear of persecution on grounds of race, religion, nationality, political opinion, or membership of a particular social group. Crossing an international border is the decisive element: someone displaced inside their own country is an internally displaced person, not a refugee, even where the cause of flight is identical.
What does refugee mean in everyday use compared with its legal meaning?
In everyday use, refugee often describes anyone who has fled danger, including people displaced inside their own country and people moving because of disaster or economic collapse. The legal meaning is narrower and attaches to a specific protection status granted after an individual or group determination. Statistics follow the legal meaning, which is why headline displacement totals are far larger than refugee totals.
How many refugees are there in the world?
Reported total forced displacement sits between 120 and No current figure people (UNHCR Global Trends; IDMC GRID 2026), of which refugees under UNHCR and UNRWA mandates are roughly a third. The remainder is mostly internally displaced people, plus asylum seekers awaiting a decision and others in need of international protection. Always check which of these categories a quoted figure covers before comparing it with another source.
Where do refugee statistics come from?
The primary series are UNHCR Refugee Data Finder for refugees, asylum seekers, and stateless populations, IOM Displacement Tracking Matrix for operational displacement tracking, and IDMC GRID for internal displacement stocks and flows. Host-government registers feed several of these, so revisions are frequent and mid-year figures are provisional.
Why do refugee numbers differ between sources?
Three reasons dominate: category definitions, reference dates, and registration coverage. One source may count only recognised refugees while another adds asylum seekers or people in refugee-like situations. Year-end and mid-year snapshots differ. And where registration is incomplete, agencies publish estimates that later revise upward. Comparing sources without aligning all three produces gaps that look like contradictions but are not.
Is refugee data free to download and reuse?
Most of it, yes. UNHCR, IOM DTM, IDMC, and OCHA publish openly licensed downloads in CSV or JSON, many mirrored on the Humanitarian Data Exchange. Licences still vary by dataset, so check the terms on each resource and attribute the originating agency rather than the aggregator.
