From mid-June until mid-August 2018, a total of 4,284 Myanmar nationals were surveyed in the province of Tak, of whom 3,765 were identified as migrant workers. The 3,765 migrant workers fell into two different migrant groups. The first group was comprised of incoming migrants, arriving in Thailand prior to starting employment and the second group of outgoing migrants, returning after their employment ended. Two different survey tools were designed to capture the most accurate information possible for both target groups. The findings help to identify migration patterns as well as common challenges and vulnerabilities and can be used to better direct policy and programming for the protection and assistance of migrant workers.
