Following mass social protests in 2019 and the enactment of a national security law in 2020 in Hong Kong, a significant proportion of Hong Kong people considered migrating to another country. At the same time, the COVID-19 pandemic had spread rapidly around the world. This background provides researchers with an excellent opportunity to study the possible impacts of a pandemic on migration decisions and planning. We investigate whether the migration intention and the planned timing of migration of Hong Kong people have changed with the COVID-19 pandemic situations both locally and abroad. We also examine if the impact of the pandemic might have varied with people's age, gender, education, and parental status. Data are from a random-sampled survey (N=2,492) conducted in 2021-2022, which collected socio-demographic information and migration intention and planning of Hong Kong people with a British National (Overseas) status. We find that a more severe COVID-19 situation in Hong Kong is positively associated with one's migration intention. The migration intention of younger and more educated people is more strongly associated with the COVID-19 situation in Hong Kong. However, the COVID-19 situation in the UK is not significantly associated with one's migration intention. Among people who intend to emigrate, a more severe local COVID-19 situation is positively associated with uncertainty about the timing of migration. We conclude by highlighting the significance of global pandemics in shaping migration decisions.
