Côte d'Ivoire's informal economy is a significant component of its economic landscape, contributing to GDP and employment in ways that are often not captured by official statistics. The analysis employs a mixed-methods approach, combining qualitative insights from interviews with key informants and quantitative data from national surveys to explore the dynamics of the informal economy within Côte d'Ivoire's economic context. A notable finding is that the informal sector accounts for approximately 40% of GDP in Côte d'Ivoire, highlighting its substantial contribution despite regulatory challenges and potential tax evasion. The study underscores the importance of integrating informal economy data into official statistics to accurately reflect the economic reality of Côte d'Ivoire. Policy recommendations include the need for a more inclusive approach in GDP calculations, fostering an environment that supports both formal and informal economic activities without stifling growth or exacerbating inequality.
