Pew Research Center has published a new report measuring the size and characteristics of the unauthorized immigrant population in Europe, providing the first comprehensive set of estimates of Europe’s unauthorized immigrants in nearly a decade. 
In this session, Dr. Mark Hugo Lopez will present the Center’s new estimates and the demographic composition of this population. The presentation will also include a comparison between the US and Europe, and a discussion of the methods used in developing these new estimates.
