PUB2020/006/EL THE FUTURE OF MIGRATION TO EUROPE: A SYSTEMATIC REVIEW OF THE LITERATURE ON MIGRATION SCENARIOS AND FORECASTS Rhea Ravenna Sohst Jasper Tjaden Helga de Valk Susanne Melde April 2020 Funded by the European Union THE FUTURE OF MIGRATION TO EUROPE: A SYSTEMATIC REVIEW OF THE LITERATURE ON MIGRATION SCENARIOS AND FORECASTS Authors: Rhea Ravenna Sohst, Jasper Tjaden, Helga de Valk and Susanne Melde Effective migration management requires some degree of anticipation of the magnitude and nature of future flows. In response to these needs, two types of approaches have emerged in the literature in recent years: (a) migration forecasts, which provide quantitative estimates of future migration, and (b) migration scenarios, which develop different storylines and thereby emphasize flexibility of thought on future migration. This report presents the results of a systematic literature review of migration forecasts and scenarios. Over 200 relevant publications were screened to summarize the results of the studies and information about the context in which they were produced. The report outlines key definitions, methodological approaches and lessons learned from the evidence produced over the past several decades. It is a comprehensive overview that will be of interest to both scientists and practitioners who wish to navigate this growing field.
