The World Migration Report (WMR) is IOM’s flagship publication, having been produced biennially since 2000. The WMR responds to a clear and growing need for rigorous, balanced and evidence-based research and analysis on migration at a time of heightened interest in the topic.

The World Migration Report 2020 is the tenth in the flagship series. In Part I of the report, readers can examine the key data and information on migration globally. The thematic chapters of Part II provide an evidence-based analysis of complex and emerging migration issues.

With these contents, the Report is able to meet the needs of those with a general interest in migration as well as those needing more in-depth analysis, including people who work in migration policy, practice, research and communications.

Recent editions have been widely utilized by policymakers, media outlets, academics, students, and migration practitioners. Journalists and researchers have referenced the past two editions of the Report in 117 blogs, 251 newspaper articles and more than 790 academic publications.

This flagship World Migration Report has been produced in line with IOM's Environment Policy and is available online only. Printed hard copies have not been made in order to reduce paper, printing, and transportation impacts.  

The World Migration Report is produced by the Migration Research Division (MRD), in collaboration with some of the leading academic and applied researchers and other migration experts from across the world. Click here to find out more about the Division.

El Heraldo de México
- Adriana Delgado Ruíz, 28 January 2020, “Migrar, como derecho humano,” El Heraldo de México, available in Spanish here.

“El Informe sobre las Migraciones en el Mundo 2020 de la Organización para las Migraciones…dice que somos el segundo país, únicamente después de India, con el número más alto de migrantes residentes en el extranjero…Si bien es cierto que una nación puede cerrar sus fronteras con el argumento de su bienestar interno, ¿puede un país con tantos intereses internacionales y regionales cerrarse a una situación en la que está más que involucrado?”

Stavangar Aftenblad
- Marte CW Solheim, 21 January 2020, "Norweigan’s attitudes towards immigration and immigrants are increasingly positive.” Stavangar Aftenblad, available in Norwegian from here.

“Migrasjonen aukar, og migrasjonsmønster har vorte meir komplekse. Ifølgje den ferske rapporten World Migration Report 2020 frå International Organization of Migration (IOM), vert det peika på ein ofseleg auke i internasjonal migrasjon, og at internasjonale migrantar no er estimerte til å utgjere omlag 272 millionar menneske globalt, der omlag to tredelar av desse er arbeidsmigrantar…Men trass i denne auka migrasjonen, og trass i frammarsjen av høgrepopulistiske parti, så kan ein observere at haldningar til innvandring er relativt stabile i Noreg. Til dømes syner årets SSB-undersøking at 56 prosent gjev uttrykk for at moglegheitene for asylsøkarar og flyktningar bør vere uendra, samanlikna med i dag.”

World Economic Forum
- Charlotte Edmond, 10 January 2020, “Global migration, by the numbers: who migrates, where they go and why.”, World Economic Forum, available in English here.

“While the overall figure has remained relatively stable as a proportion of the global population, the numbers from the World Migration Report 2020, published by the International Organization for Migration (IOM), clearly demonstrate the impact that events of the past two years have had on the movement of people around the world.” 

CNN Español
- 18 December 2019, “Una de cada 30 personas es inmigrante: 6 gráficas para este Día Internacional del Migrante”, CNN Español, available in Spanish here.

“Una de cada 30 personas es migrante. Así lo establece la Organización Internacional para las Migraciones (OIM) que en su Informe sobre las migraciones en el mundo 2020 indica que hay 272 millones de migrantes internacionales en todo el planeta. Una cifra que, si bien es masiva, representa el 3,5% de la población total. Y esto, explica la entidad, “significa que permanecer en el país natal sigue siendo la norma casi universal’.”

Africa Times
- AT editor, 27 November 2019, “IOM: Climate change a clear driver of African migration,” Africa Times, available in English here.

“The 500-page report from IOM, available at this link, delivers a comprehensive assessment of migration drivers for Africa and the wider international community.”

Praise for the World Migration Report: IOM Member States and partners

Canada welcomes the publication of the 10th edition of IOM's World Migration Report, a vital information tool for understanding current migration trends and pressing global issues. I can attest that the Report is used by policymakers worldwide, including at all levels of the Canadian government, academia, and civil society, and for that, we want to extend our gratitude for publishing such a valuable tool and reference.

Statement by the Government of Canada, IOM 110th Session of the Council, 2019.

Felicitamos a la OIM y a todo el equipo editorial y de investigacion por su valiosa contribuci6n al studio "Migraciones en el Mundo 2020". Por su naturaleza misma, la compleja dinamica de la migracion mundial, no puede cuantificarse en todos sus detalles, sin embargo, como demuestra este informe, existe un conjunto cada vez mayor y mejor de datos e informacion que pueden ayudar a comprender con mas exactitud, las caracterfsticas basicas de la migracion en estos tiempos de incertidumbre.

Declaracion de El Salvador en la centesima decima reunio del Consejo de la OIM, 2019.

La OIM tiene un gran potencial para generar datos sobre la migración, a partir de su amplia presencia en el terreno. El Reporte sobre las Migraciones 2020 es prueba de este cúmulo de conocimiento.

Several chapters of the [2018] report are perfect for introducing my students to new topics, as was the case in my recent course on ‘migration and health’. The report is very well-written and nicely researched.
