Evolving Pathways of Departure and Return in Rural Thailand

open access: yesPopulation, Space and Place, Volume 32, Issue 5, July 2026.
ABSTRACT This paper draws on a forty‐year longitudinal (1982–2022) village study of Thailand to reflect on how circulation persists, but in new ways. We trace evolving migration flows over a period during which Thailand progressed from low‐income to upper‐middle‐income status, and Non Tae and Tha Song Korn from semi‐subsistence rice‐growing communities
