The mid-term evaluation of the sustainable development objectives of the social sub system in Kinshasa in the Democratic Republic of Congo It’s since 2015 that the DRC is engaged in the implementation of the Sustainable Development Goals (SDGs). In 2024, an evaluation study was deemed necessary to assess the strategies for its implementation and the immediate results of the activities already carried out. This is mainly because certain priority targets for SDGs by the DRC must be attained in 2020 for the first five years. The aim is to find out to what extent the activities already carried out have made it possible to improve the social conditions of the populations of Kinshasa in the DRC. This evaluative study of SDG is an enrichment of the field of sociology in general, and its pragmatic dimension of project management, in particular. The main objective is to understand the perception of the immediate effects of the 2030 agenda by the populations of Kinshasa. We started from the assumption that: the population of Kinshasa through that the objectives of sustainable development of the social sub system are achieved at low levels.
