In this article we present the design of a model in dynamic systems for studying the socio-economic and sociodemographic characteristics of the population belonging to the early childhood (population between 0 to 5 years of age), children and adolescents in the city of Pereira, Colombia. The model allows to design programs and/or policies of care provided to the population-early childhood according to the patterns of vulnerability and future risks that are obtained with it. The structure of the model is based on a hybrid approach, and some socioeconomic components that are characteristic of the selected location and that have a large stake in the future of the population dynamics of this group. The results obtained from the simulation of the model were able to identify the main variables on which work is to be done, as well as the convergence of the same. In addition to these aspects, was able to build prospective analyzes that enable to consolidate a series of present actions to mitigate some evident future problem.
