The Mixed Migration Review is the annual report of the Mixed Migration Centre. The report offers a deep analytical dive into the world of mixed migration, using the mixed migration lens to offer a critical framework to understand and respond to the complex characteristics and protection imperatives that defines contemporary human mobility. The report is based on a large body of data and aims to contribute to an evidence-based and differentiated understanding of mixed migration movements. The thematic focus of the 2020 report is on urban migration and cities as key destinations of internal and international migration as well as forcibly displaced. It highlights topics such as access to rights and services, health and Covid 19, as well as the impact of climate change on migrants and refugees in cities. The report also sheds light on different global and regional processes that influence urban approaches to mobility and asks what we can learn from how cities govern migration issues.
