Nicolas Nogue’s *Les Chiffres de l'architecture* offers a data‑driven exploration of the built environment, focusing on the statistical dimensions of architectural practice in the twentieth century. Drawing on a range of economic indicators, the book examines how financial considerations have shaped design decisions, urban development, and the professional lives of architects in France. By weaving together quantitative analysis with historical context, Nogue provides readers with a nuanced picture of how numbers intersect with aesthetics and cultural trends. The work serves both scholars interested in the economics of architecture and practitioners seeking a deeper understanding of the forces that influence the creation of space.
