This thesis explores the changes in mother-daughter relations in Northeast Thailand over the last three generations in relation to migration out of this region. Qualitative interviews were done with ten families in two villages; the interviews focused on representatives of three generations of women in each family. In recent decades, in Northeast Thailand (also known as the Isan region) many people have left their hometowns because of economic hardship and agricultural instabilities to find economic opportunities. Rural people have become migrant laborers in Bangkok, regional areas, and overseas. In Northeast Thailand the kinship system is matrilineal and matrilocal, characterized by inheritance and care flowing particularly between mother and youngest daughter. Women are the core of the family system, playing an important role in the production activities of the household, trading, and religious rituals. Faced with modernity as they migrate, women change and force transformation in the family and rural villages. The thesis finds conditions of high debt, dependence on remittances, grandchild care by grandmothers, and diminishing landholdings. Although matrilineality continues, with the youngest generation, mother-daughter relationships have weakened in the areas of matrilocality and emotional closeness, but are maintained by remittances faithfully sent.
