Diffusion of fertility control is recognized as one of the main factors that contribute to reduce fertility, particularly, in low-income countries. However, in Sub-Saharan Africa characterized by poverty and high fertility, little research has been conducted on this topic. This article contributes to improve the knowledge of the determinants of fertility by considering both structural factors and aggregate pattern of spatial behaviour. We measure spatial dependence in fertility and related factors, and then assess the diffusion effect of fertility behaviour across 518 administrative divisions based on Cote d’Ivoire census data conducted in 2014. We found out that spatial diffusion in fertility is statistically significant after controlling structural characteristics of women, which means that women shaped their demand for children based on their own characteristics and the influence of ideas, informations related to fertility control. By comparing areas of residence, we found that urbanization, employment and exposure of media (television/radio) were more significant in areas with the lowest child-woman ratio than in areas with the highest fertility rate. Considering spatial concentration of women’s characteristics, the lowest cluster of female employment, educated women, women living in cities, household that owned radio/television were registered in areas with the highest child-woman ratio. However, these areas have the highest concentration of married women, who were likely to share conservative values of having many children.
