The Bicol region in the Philippines gets its name from the Bicol River, which forms from lakes and springs in Albay, Camarines Sur, and Camarines Norte provinces before exiting into the San Miguel Bay. The Bicolanos are descended from Austronesian immigrants from Southern China who arrived during the Iron Age, with many Bicolanos also having Chinese, Arab, and Spanish ancestry. The region's economy relies on crops like rice, corn, coconuts, and abaca, with Camarines Sur being a top producer of livestock, poultry, and fish. Bicolano culture and religion incorporate both indigenous Philippine and Catholic Spanish influences.
