Kim Jong-un (Korean: 김정은, Hanja: 金正恩,) also known as Kim Jong-eun or Kim Jung-eun, formerly Kim Jong-woon or Kim Jung-woon (born 1983 or early 1984), is the third and youngest son of Kim Jong-il with his late consort Ko Young-hee.
He is a Daejang, the equivalent to an American four-star general, in the Korean People's Army. Recent actions, symbolic and overt, taken in late 2010 by current head of state and "Dear Leader" of North Korea (officially, the Democratic People's Republic of Korea), Kim Jong-il, strongly indicated that Kim Jong-un is now the heir presumptive to the leadership of the nation upon Kim Jong-il's death, incapacity, or deliberate abdication. It has been claimed that he studied computer science privately in Korea.
Kim's birth date is not known for certain, but he is thought to have been born in 1983 or early 1984. The North Korean officials formerly gave his date of birth as 8 January 1983, but from late 2009 gave 1982 as his birth year, possibly as part of preparations for his anointment as successor to his father, as the adjustment would make him 30 in 2012, which is significant for the regime.
