The @nytopinion.nytimes.com provides some amazing #dataviz of the estimates (behind their paywall): www.nytimes.com/interactive/...

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
