This is the third in a series of global thematic updates on 4Mi data collected remotely by MMC about the impact of COVID-19 on refugees and migrants travelling along mixed migration routes in Africa, Asia and Latin America. After the initial roll-out of our adapted 4Mi survey focusing on the immediate impact of the pandemic in April, we moved into a new data collection phase in July, further zooming in on the impact of the pandemic on mixed migration. This third monthly thematic update focuses on how people travelling with children are affected by the COVID-19 crisis and, where relevant, how this compares to refugees and migrants who are without children under their care.
