Bill Clinton was born on August 19, 1946 in a town called Hope, with the birth name William Jefferson Blythe. His birth father died in a car accident just three months before his birth. When he was born, his mother sent him to live with his grandparents because she couldn't possibly support a child by herself. He lived with his grandparents for two years while his mother was away at a nursing school in New Orleans, trying to advance her career. When Bill was four, his mother returned to Hope, where she met and married Roger Clinton Sr. A few years later, Bill and his family moved to Hot Springs, where Bill attended school. When he was nine years old, he changed schools and went to Ramble Elementary. When Bill was ten, Roger Clinton Jr. was born, and at age fifteen, Bill took his stepfather' s last name in hopes of helping his mother's troubled relationship.

While Bill was growing up in Hot Springs, the town was troubled by gambling (赌博), but Bill had little contact with this part of society despite his parents' frequent participation (参与) in these illegal practices. As time went by, his mother' s relationship with Roger Clinton Sr. became more and more unstable.  His parents often separated.  In high school, Bill was a member of the band, student government, honor society and many other organizations. One summer at a political summer camp called Boys State, Bill ran for delegate (代表) to Boys Nation. He won this election and was on his way to Washington to meet John F. Kennedy, the president.
