The age range of 15–18 is interdisciplinary and hence complex to study in terms of education and marriage. Aggregated Data on levels of education and number of never married individuals are taken into account for this study. The concept of spatial arrangement in spatial analysis is proposed to order levels of education in order of achievement. The optimal solution that the genetic algorithm model outputs is the level of qualification that contributes to delaying underage marriages the most. With a wide solution space, the findings are ranked and overlapped with an established index to validate the ranking.
