This paper focuses on Women’s employment, which, has experienced an increasing trend since 1950s, and its association with demographic variables. Demographers, like other scholars and researchers, have shown increasing interest in studying women's employment during the recent years. This mainly lies in the substantial increase of female labour force participation and, more importantly, in significant interlink between women's employment and demographic characteristics such as marriage and fertility patterns, migration and mortality. Using both theoretical studies and empirical research, this paper analyses demographic aspects of women's employment. Iran has experienced substantial demographic changes particularly in terms of marriage and fertility patterns as well as the increasing achievement in women's university education and positive attitudes towards women's employment over the past year. Such changes facilitate the compatibility of family duties and women's work outside the home. Accordingly, the theoretical discussion and empirical evidence of this paper also provide good basis to explain demographic consequences and dimensions of women's employment in Iran.
