The commune in the Ain department whose population quadrupled in five years

Saint-Maurice-de-Beynost is a French commune located in the Ain department. It experienced a major demographic explosion between 1926 and 1931 thanks to the establishment of a factory of the Société lyonnaise de soie artificielle. This rapid industrialization caused the number of inhabitants to quadruple in only five years, changing the agricultural village into an industrial town.
