Title:Using Social Media Data to Estimate Migration
Abstract: Social media data have generated new opportunities for the study of human migration and geographic mobility. However, these data also come with important limitations due to several types of bias. In this talk I discuss two collaborative projects that leverage social media data to estimate stocks and flows of international migration. First I show the use of aggregated data from the Facebook's advertising platform to estimate migration stocks. This work indicates the feasibility of estimating stocks of migrants using data from Facebook Adverts Manager, a tool developed for advertisers to target users with certain characteristics, such as age, gender, country of origin, education level, or topical interest. Second, I present an approach for harmonizing rates of migration flows using geo-located micro-level Twitter data. The two examples highlight the importance of combining traditional and new sources of data for the study of migration and mobility. #5715
