The various questions on the capacity of companies to self-build stress the need for sociospatial integration of all actors. However, urban construction in African cities forces exclusion and accelerates the impoverishment of socially weakened groups, giving rise to deviant behaviors such as prostitution, whose attempts to eradicate public policies have chess. For this research, the eradication of prostitution in the city of Kara should pass not by sex workers but rather by their clients. This is why through a theoretical and methodological triangulation (documentary, qualitative and sociometry), the research first tried to understand how the girls in Kara enter prostitution, in order to understand how they are looking for clients and build their networks of prostitution. From there, it was possible to identify the two recurring profiles of clients of sex workers in the city of Kara: the first classic profile of individuals in the informal sector between the ages of 30 and 40; and the second, apprentice profile, where individuals are 20-30 years old and unemployed.
