Women's social and economic participation is considered to be an important development indicator. In developing countries, however, social and cultural factors have limited the opportunity for women's participation in social and economic structures. This paper examines the factors which promote the rate of participation by women in the labor market within the provinces of Iran. The methodology applied is a regression model utilizing panel data. The results indicate; factors influencing the women's participation in the labor market include level of education, the incentive to gain income, and the rate of male unemployment. Negative factors include rural-urban migration (the rate of urbanization), rate of women's unemployment, and the birthrate. The trend of women's participation in the labor market of Iran is V-shaped in which has experienced an upward turn in recent years.
