Combining Facebook and traditional survey data to predict migrant stocks in the United States

Understanding migration patterns and how they change over time has important implications for understanding broader population trends, effectively designing policy and allocating resources. However, data on migration movements are often lacking, and those that do exist are not produced in a timely manner. Social media data offer new opportunities to provide more up-to-date demographic estimates and to complement more traditional data sources. Facebook, for example, can be thought of as a large digital census that is regularly updated. However, its users are not representative of the underlying population.

In this presentation visiting scholar Monica Alexander will combine data from Facebook's Marketing API with data from the American Community Survey to generate 'nowcasts' --- present and near-future predictions --- of migrant stocks in the United States. She will present a Bayesian hierarchical framework which probabilisitically combines information from the two sources, while accounting and adjusting for different types of biases and error. Combining data sources and modeling strategies provides the ability to weigh down inconsistencies and extract valuable insights without ignoring existing information.
