The COVID-19 pandemic has impacted about 1 billion migrants (both international and domestic) in a variety of ways, and this book demonstrates how COVID-19 has widened the gaps between citizens, non-migrant and migrant populations in terms of income, job retention, freedom of movement, vaccine etc. While there is an emerging literature studying the impacts of COVID-19 on migration, the situation in Southeast Asia has not received much scholarly attention. This book fills the literature gap by studying the experiences of migrants and citizens in Brunei, Malaysia and Singapore and highlighting how the pandemic has exacerbated inequalities between and within the groups. These three countries are studied due to their high reliance of migrants in key economic sectors. Findings in this volume are derived from a qualitative approach, complemented by secondary data sources. This book is appropriate for undergraduate and postgraduate students of population studies, epidemiology, political science, public policy and administration, international relations, anthropology, psychology, sociology, and migration and refugee studies. Migration and labour scholars benefit from the nuanced comprehension about how a pandemic could cause a schism between migrants and the population at large. Policymakers may consider the proposed recommendations in the book to improve the migration situation.
