Daloa, a military post during the colonial period, was promoted after independence, helping to establish it as the third largest city in Côte d'Ivoire. This demographic and spatial dynamic, without a real industrialization policy, took place in the context of a formal employment crisis. To become part of the urban society, poor populations engage in the practice of many activities, mostly informal. Also, urbanization and proliferation of informal activities seem synchronous. Thus, the objective of this article is to show that urban dynamics explain the flowering of informal activities in the city of Daloa. The method consisted of estimating through the scatterplot the coefficient of determination of the linear regression. The results of this statistical test show that urban dynamics account for 95% of the proliferation of informal activities. This urban dynamic nonetheless forms part of a causal system linked to the historical context of the city's evolution and to the sociodemographic profile of the population.
