A migrant is defined as any individual who is in the process of moving or has already moved across an international border or within a State away from their dominant place of residence; irrespective of their legal status; whether the migration is voluntary or involuntary; what the causes for their movement are; and what the length of their stay in their host community is (IOM, 2019).

Protecting migrants’ health has been identified as one of the 21 priorities under the “ASEAN Post-2015 Health Development Agenda.” Thus, in collaboration between the Association of Southeast Asian Nations (ASEAN) Secretariat and the International Organization for Migration (IOM), this “ASEAN Regional Case Studies on Migration and Health in ASEAN” Report aims to examine and explain recent migration trends, flows and patterns throughout the 10 ASEAN Member States, while taking into consideration recent developments, legislative commitments, efforts and initiatives in the field of migration and health.
