International Migration 2020 Highlights [EN/RU/ZH] Format Executive summary In 2020, the COVID-19 pandemic affected drastically all forms of human mobility, including international migration. Around the globe, the closing of national borders and severe disruptions to international travel obliged hundreds of thousands of people to cancel or delay plans of moving abroad. Hundreds of thousands of migrants were stranded, unable to return to their countries, while others were forced to return to their home countries earlier than planned, when job opportunities dried up and schools closed. While it is too soon to understand the full extent of the impact of the pandemic on migration trends, the present Highlights indicate that the disruptions caused by the COVID-19 pandemic may have reduced the number of international migrants by around 2 million globally by mid-2020, corresponding to a decrease of around 27 per cent in the growth expected from July 2019 to June 2020.
