According to the 2020 census, it has a population of 132,650 people. San Carlos City was formerly named Nabingkalan, deriving its name from Nabingka, the daughter of a chieftain of the Negrito settlement in the area, who ruled the barrio during the early part of the 17th century. She was famous for her loveliness and mental and physical prowess. After her death, the people mourned for two years, and to perpetuate her memory, named the barrio after her. The settlement was later bought by Carlos Apurado from Badian, Cebu, who with the help of fellow pioneers developed the settlement into a thriving Christian village. In 1856, Buglas (Negros) Island, as a politico-military province under the Spanish Empire, was divided into two provinces, west Negros under Iloilo and east Negros under Cebu. Nabingkalan was under the jurisdiction of Calatrava municipality in Iloilo. Don Emilio Saravia, the first political-military governor in the island during the Spanish era, renamed the barrio and established it as a pueblo.
