San Carlos is small, with a population of 154 (2013) of Mestizo ethnicity. The village was set up by a group of families around 1970 from the larger town of Guinea Grass Town. Other inhabitants are originally from Guatemala, immigrating to Belize during the tumultuous years of the Civil War. The village is still technologically primitive. Water is pumped from wells for washing and bathing. Rain water tanks collect plenty of drinking water during the months of June thru December. An NGO donated 25 solar panels to the community providing evening light to 25 homes. A few families have purchased their own solar panels while a few families rely solely on kerosene lamps or candles. There are 32 occupied homes and 36 families in the Village. Additionally, a few villagers own generators to pump water from the wells, power washing machines, light, television, and irrigation systems.
