IOM data overview
Through a large footprint of offices worldwide, the International Organization for Migration (IOM) collects and reports on original data from a number of sources in its own programmes and operations. Some of this information is publicly available while other data is collected for internal use only. In all cases, data collection and management adheres to IOM’s Migration Data Governance Policy. In cases where IOM processes beneficiaries' personal data, this is done in full respect of IOM’s Data Protection Principles. In principle, only anonymized data may be made publicly available. In no case would personal data be made publicly available if the beneficiary has not consented to it.
Quantifying environmental migration is challenging given the multiple drivers of such movement, related methodological challenges and the lack of data collection standards. Some quantitative data exist on population displacement within a country, and to a lesser degree across borders, due to natural hazards. However, for migration due to slow-onset environmental processes, such as drought or sea-level rise, most existing data are qualitative and based on case studies, with few comparative studies. While data gaps persist, research methodologies are constantly being improved.
TALKING MIGRATION DATA: What do we know about data on environmental migration?
Disaster displacement forces millions of people away from their homes every year. Many more move in the context of environmental changes. Estimating the number of people affected remains a challenge for the international community. Atle Solberg, Head of the Platform on Disaster Displacement, and Francois Gemenne, specialist of environmental geopolitics and migration dynamics, share their views on this topic.
