Woods' father, Earl Woods is a Vietnam War veteran and a retired U.S. Army lieutenant colonel, of mixed Black, Chinese and Native American ancestry. He is now the chairman of his son's charitable foundation, the Tiger Woods Foundation (see section Charity and youth projects below). Woods' mother, Kultida Woods, is originally from Thailand, and is of mixed Thai, Chinese, and Dutch ancestry. This makes Woods himself one quarter Chinese, one quarter Thai, one-quarter African American, one eighth Native American, and one eighth Dutch[1]. He refers to his ethnic make-up as Cablinasian (a portmanteau of Caucasian, Black, American-Indian, and Asian), a term he made up himself.
