An analysis of demographic characteristics from the gender perspective represents a contribution to enlightening the social relations between female and male population in Belgrade. Gender specificity and explicitness of socio-demographic structures indicate to different positions and statuses of the female and male populations. There are more females than men in the total population of the capital city of Serbia. The sex imbalance of age groups is determined by gender differences in the number of born boys and girls, in migration characteristics and in the level of mortality. The male population is greater in the age group up to 20 years old, while the female population is more numerous among the middle-aged and older generations. Gender differences in marital structure, level of education and economic activities cannot be reduced only to demographic limits. A larger rate of married persons among the males in relation to female population is determined by the different behavior in view of remarriage in case of divorce or death of partner. Women are widowed or divorced more often than men, which can be interpreted as a less favorable position in everyday functioning, especially when the women have small or school-age children, as well as in the case of older women. Gender differences in the level of education of Belgrade population are not exceptionally pronounced and are a consequence of unfavorable positions of older women to a certain degree. Differences in economic activity, among other things, are determined by uneven utilization of female and male work force. The rate of economic activity is greater in the male population, and the coefficient of economic dependency in the female population. The gender difference in the rate of supported persons among the work capable population increases the unfavorable social position of women. The characteristics of socio-demographic structures of female and male population of the city of Belgrade vary by areas. The manifestation of gender differences can be connected with demographic and sociological specificities of the proper and wider city region. The rate of divorced women in Belgrade proper is especially marked as well as the rate of supported persons in the female population in Belgrade suburbs. Imbalance in the education level between women and men is less distinct than the differences in educational structures by regions with population of both sexes.
