The village has always been turned towards agriculture thanks to its fertile and rich lands. In the 19th century, it will be marked by the rural exodus but despite the loss of inhabitants, Ansignan will remain an important village.
In 1903-1905, a hydro-electric plant was built to produce and supply electricity to the villages of Ansignan, Lesquerde, Saint-Arnac and Saint Paul de Fenouillet. The building existed until 1965.
Vines were mainly cultivated but the peach trees of Ansignan gave the village a good reputation. In 1924, the cooperative cellar of ANSIGNAN was created. This grouping of winegrowers allowed, at that time, to pool the means of production, to increase the bargaining power on the markets and thus to maintain the viticulture. But little by little the cultivated surfaces decline and the cellar merges with that of Caramany in 1993.
Today, Ansignan has a population of 165. The village is rural and the cultures continue thanks to the installation of young producers of olive oil, Clots Das Vigne, and the Domaine D'ANSIGNAN which since 2016 repurchase lands, in vineyards or not and makes live again this historical soil.
