Demography Callosa has 7.888 residents (INE 2010). A 30.4% of the census are foreigners, mainly from Latin America (mainly Ecuador and Bolivia) and the European continent.

Farmers are partners in a cooperative that handles the marketing of fruits, intended mostly for exporting; their main destinations are France and Italy. Recently the City Council managed the "denominación de origen" (DO) and thus, the Council of the Designation of Origin of loquats from Callosa d'en Sarrià, with a view to establish quality standards for the loquat produced in Callosa and its region.
