Georeferencing of health data gains relevance as the analysis and assessments of risks to public health incorporate variables related to the environment and to the socioeconomic profile of the population. Early motherhood does not occur at random within the society. This study aims to identify the spatial dependence of adolescent pregnancy within socioeconomic aspects and social vulnerability. Presuming the existence of a spatial dependence between these facets, the present work used the Exploratory Spatial Data Analysis. This tool is a collection of techniques which describes and visualizes spatial distributions; identifies atypical circumstances; discovers patterns of spatial association; makes clusters of similar values; and suggests spatial schemes or other forms of spatial heterogeneity. One of the results highlighted is the statistically significant correlation between social vulnerability and the rate of live births for women between 12-19 and 20-29 years of age. The study identified: (a) the presence of clusters with high proportions of teenage mothers associated with poorer socioeconomic conditions; and (b) a decrease in the proportion of teenage mothers in areas of better conditions, in which the highest number of births occurred in the 20-29 years and above 30 age groups. This study may help the organization and planning of actions and strategies in the area of sexual and reproductive health for young and adolescent audiences.
