Migration data sources
The demands for migration data arising from the 2030 Agenda for Sustainable Development have prompted the international statistical community to review the use of traditional sources for migration data, such as population and housing censuses, household surveys and administrative records. There is also increased interest in looking for alternative sources to enhance the collection and analysis of migration data. The better use and understanding of existing data sources are essential to improve migration management and policy. Information about migration comes from a variety of data sources that have strengths and limitations and can be used to produce different migration statistics.
Big data, migration and human mobility
The term "big data" includes anonymized data that are generated by users of mobile devices, internet-based platforms, or by digital sensors and meters, for example, satellite imagery. With about 5.1 billion unique mobile users, and around 4 billion active internet users around the world (We Are Social - Hootsuite, 2018), such "digital traces" present an enormous opportunity to complement traditional sources of migration data and improve knowledge of various aspects of migration. This is all the more relevant in light of the current data gaps and the need to monitor progress towards the migration-related targets in the Sustainable Development Goals (SDGs). The potential of these innovative sources, however, comes with significant challenges.

4 reasons why Data Collaboratives are key to addressing migration
Migration data are often scattered, hard to access, and sometimes proprietary, limiting policymakers' ability to design well-informed and targeted policies. Stefaan G. Verhulst and Andrew Young of the GovLab at the NYU Tandon School of Engineering explain how Data Collaboratives in the migration field can help address these data and information challenges.
