Labour force participation rates of women in Turkey are quite low with respect to European Union member countries. Cohort analysis application was used with an aim of determining the reasons of this situation and how extent these reasons effect woman labor force. Cohort analysis is used by many researchers who establishing different models in different contexts. The model, which was developed by Beaudry and Lemieux (1999), was used for the application of cohort analysis. In this model, factors effecting woman labor force are examined by seperaring these effects in three categories: macroeconomic factors, ages of women in a cohort and specific effects of a cohort. It is seen that age effect amd cohort effect are significant on women’s labor force in Turkey. Also, it’s determined that women’s labor force is effected by men’s labor force as a macroeconomic effect.
