 The commune of Aigrefeuille d'Aunis officially became an Urban Commune after the population census of 1982.This classification criterion was established by INSEE from the fact that the town has gradually spread to several areas, localities, and villages which in the 19th century were clearly separated from the main town.Thus, in his communal notice that he issued for Aigrefeuille, M. A. Gautier informed his contemporaries that the commune had ten villages and eight hamlets, besides the town, a situation that stood in 1839.
