 New economic activities were little source of employment, while the vineyards had required abundant labour.Thus, the changing demographics of the commune of "Aigrefeuille d'Aunis" and its canton followed from the impact of the serious wine crisis, resulting in an almost continuous demographic decline from 1876 to 1946.During this period, the city recorded a dramatic decline in its population with a population loss of 607 inhabitants, a decrease of one-third of the population (-32.3%).
