📦Download the complete estimates of annual global migration flow and stock datasets: 🔗zenodo.org/records/157783… 🔗huggingface.co/datasets/ThGas… 🛠Access the full deep learning architecture and plot reproduction code on GitHub: 🔗github.com/ThGaskin/Migra… @LSEnews @HKUFoSS @IIASAVienna
📊The data explorer features a variety of interactive data visualisation methods. Switch between the global maps, chord diagrams and Sankey charts to track migration across different country corridors - with options for toggling map types, filtering chord sizes and many more
🚨Out today in @Nature our new paper uses deep learning to map four decades of global human migration. By building the first comprehensive dataset of global annual flows (1990-2023), we reveal that migration has nearly tripled since 2000. 🔗nature.com/articles/s4158…
Global migration has increased from 13 million people per year in 2000 to around 35 million in 2023. The data, published in Nature today, come from the most detailed maps of global migration produced in the 33 years. go.nature.com/444iUfq
The @nytopinion provide some amazing #dataviz of the estimates (behind their paywall): nytimes.com/interactive/20… #dataviz
📢New paper out on measuring global #migration flows using online data in @PNASNews We use privacy-protected records from over 3 billion Facebook users to estimate migration flows between 181 countries, accounting for biases in social media usage. 🔗pnas.org/doi/10.1073/pn…
Full #OpenAccess to the estimates will come soon, when the journal paper based on the work is published.
An @arxiv paper on our method, led by @Meta Data for Good researchers, is out now: arxiv.org/abs/2504.11691
The @nytopinion features a #dataviz of our new global migration flow estimates. nytimes.com/interactive/20… Using privacy protected records from three billion Facebook users, we estimated country-to-country #migration flows at monthly granularity for 181 countries.
