The increase in the proportion of elderly people is observed globally, including in many countries such as Congo. This phenomenon, marked by the progressive aging of the population, presents significant challenges to social security systems in Africa, particularly in Congo. The primary objective of this research is to develop a resilient and sustainable social security system to cater to the needs of Congo's aging population. Our study employs a mixed-methods approach, combining qualitative and quantitative data. Data collection was conducted through a questionnaire involving 90 workers in the Congolese social system. The results reveal a lack of awareness and understanding of the benefits of social security, insufficient social benefits, delayed payments, and inadequate integration of informal sector workers.
