Human migration has surged since 2000 — these maps reveal where people are going
Summary
Nature reports on a study that uses artificial intelligence to fill gaps in migration data, producing high-resolution maps of global population movements from 1990 to 2023. Researchers trained a hybrid model combining classical mathematical approaches with deep learning on multiple data sources, including UN data, national statistics, and social media, revealing drivers like economic change and conflict. The analysis enables more detailed migration insights and is complemented by an online portal for exploration.
