🚨Out today in @nature.com our new paper uses deep learning to map four decades of global human migration. By building the first comprehensive, four-decade dataset of annual flows (1990-2023), we reveal that global migration has nearly tripled since 2000. 🔗 www.nature.com/articles/s41...

We estimate a 64% decrease in migration during the #COVID19 pandemic, followed by a rebound in 2022 to a rate 24% higher than pre-pandemic levels. #poptwitter @iiasa.ac.at

We estimated 39.1 million international migrants in 2022, representing 0.63% of the population in the sampled countries. Our figures correlated strongly with migration data from official statistics. The estimates are #OpenAccess on HDX: data.humdata.org/dataset/inte...

📢New paper out on measuring global #migration flows using online data in @pnas.org 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 🔗https://www.pnas.org/doi/10.1073/pnas.2409418122
