The aim of this paper is to analyze the economic development of Três Lagoas - MS. More specifically, we seek to identify and characterize the development stages of this place having as theoretical framework the "Stages of development Economic Growth" proposed by Rostow (1961). This is a theoretical/analytical exercise. The main results indicate that this process of development passed through the first three stages of this theory, and that presents a set of prerequisites able to boost the take-off.
