Population policy measures address all fertile women in Serbia, and the aim is to mobilize the largest number of women to give birth. Although strong response is desirable, not all women react, or at least not to the same extent, to the population policy measures which are financially based in Serbia. In this paper our intention was to identify which categories of fertile women could give greatest demographic benefit in the near future considering current population policy measures. We assumed that age and socioeconomic characteristics are the most relevant for the different response of women. Considering past structural changes of women population, and population projection results, we tried to define which categories of fertile women can give the greatest demographic benefit to the increase of birth level until 2041.
