The purpose of this study was to analyze the participation of females in the labor force in Thailand between 1960 and 1970. The demographic variables tested were age, sex, migration rates, employment, youth dependency ratio, and educational attainment. The findings of the study indicate that demographic trends are affecting economy, culture, and roles of women. Female participation rates in the economic sector increased, particularly in Bangkok. Although many Thai women still occupy traditional female roles, there are indications that sex roles are being modified as related to industrialization and urbanization.
