Welcome to the Migration Data Portal

About the Global Migration Data Portal

The Portal is a unique access point to timely, comprehensive migration statistics and reliable information about migration data globally. The site is designed to help policy makers, national statistics officers, journalists and the general public interested in the field of migration to navigate the increasingly complex landscape of international migration data, currently scattered across different organisations and agencies. 

Especially in critical times, such as those faced today, it is essential to ensure that responses to migration are based on sound facts and accurate analysis. By making the evidence about migration issues accessible and easy to understand, the Portal aims to contribute to a more informed public debate.

The Portal was launched in December 2017 and is managed and developed by IOM’s Global Migration Data Analysis Centre (GMDAC), with the guidance of its Advisory Board, and was supported in its conception by the Economist Intelligence Unit (EIU). Over the years, the Portal has been made possible with funding received from the Government of Germany, the Federal Department of Foreign Affairs (FDFA) Switzerland, the Government of the United Kingdom of Great Britain and Northern Ireland, and the Government of the United States of America, as well as from the European Union and unearmarked funding granted to the International Organization for Migration (IOM) and internally allocated through the Migration Allocation Resource Committee (MiRAC).

Explore the Migration Data Portal

The six main sections of the Portal are designed to help you quickly and easily find the data and information you need.


Our interactive dashboard visualizes international, publicly-available and internationally comparable migration data. In our national data section, you can explore official national migration data for four pilot countries -- Switzerland, South Africa, New Zealand and Germany -- as well as estimates on national and subnational migration from WorldPop.


  • Thematic overviews explain how various aspects of migration are measured, what are the data sources, their strengths and weaknesses and provide context and analysis of key migration data.
  • Regional overviews explain regional aspects and trends, data sources, their strengths and weaknesses.
  • Spotlight sections serve as an entry point to understand the complex relationship between available migration and displacement data on specific contexts, such as food security and human mobility
  • Our expert articles and videos provide a place for the migration data community to share their opinion on new developments and policy, new data or methods.


Migration data tools are regularly added to help you find the right tools, guidelines and manuals on how to collect, interpret and disseminate migration data.
