The introduction of Child Support Grant (CSG) in South Africa in 1998, gave rise to lots of unfounded rumours that it brings perverse incentives especially for teenagers to fall pregnant in order to access the grant. This research wants to determine whether there is a link between CSG and teenage fertility. The researcher in this research followed a triangulation of methods by using both quantitative and qualitative methods. Retrospective tables on CSG reports were analysed and correlation analysis was used to determine the link between the two variables. For qualitative data, in-depth interviews were conducted with teenage mothers and thematic analysis was used to analyse the data. The results obtained in this research suggests that there is no evidence that explicitly link CSG and teenage fertility rate except that there are other exogenous factors leading to the registration of the child for CSG.
