Vann Nath was born in Phum Sophy village, Srok Battambang district, Battambang Province in northwestern Cambodia. The exact date and year of his birth is unknown, but it was common for poor Cambodians born in rural areas not to have a proper birth certificate. He was educated at Wat Sopee pagoda as a child. His parents were separated, and he had two brothers and an older sister. They earned a living by selling a type of Khmer white noodles called 'num banhchok'. They were so poor that Nath had no chance to get a proper education. By the time he was 14 or 15, he was working at factory jobs for 500-600 riel a month (less than US$0.25).
