The project is to show the social diversity of the habitants of Paris. Centered on Line 12 of the Paris metropolitan, the project allows you to view several statistical information such as the unemployment rate, students, the average age, political orientation, the average income or celibacy rates. Line 12 is a efficient sample of the population of Paris as it traverses the city from the north to the south through very different neighborhoods. The poster series consists of 29 posters, one for each station and each poster pose to the reader the question of its apartenance and its location relative to the average of its neighborhood. To view these statistics, a graphic system was created for each data and declines on each poster.
