Americans, or American people, are the citizens of the United States of America. The country is home to people of different national origins. As a result, Americans do not equate their nationality with ethnicity, but with citizenship. Aside from the Native American population, nearly all Americans or their ancestors immigrated within the past five centuries.

Despite its multi-ethnic composition, the culture held in common by most Americans is referred to as mainstream American culture, a Western culture largely derived from the traditions of Western European immigrants. It also includes influences of African American culture. Westward expansion integrated the Creoles and Cajuns of Louisiana and the Hispanos of the Southwest and brought close contact with the culture of Mexico. Large-scale immigration in the late nineteenth and early twentieth centuries from Southern and Eastern Europe introduced a variety of elements. Immigration from Asia, Africa, and Latin America has also had impact. A cultural melting pot, or pluralistic salad bowl, describes the way in which generations of Americans have celebrated and exchanged distinctive cultural characteristics.

Vin Diesel (born Mark Sinclair Vincent; July 18, 1967) is an American actor, writer, director and producer. He became known in the early 2000s, appearing in several successful Hollywood films, including The Fast and the Furious and xXx. He founded the production companies One Race Films, Tigon Studios and Racetrack Records.

Vin Diesel was born in New York City, the son of Delora, a psychiatrist and astrologer. Diesel has white and black ancestry. He has described himself as "definitely a person of color" and stated that he is "of ambiguous ethnicity – Italian and a lot of other stuff." Diesel has never met his biological father, and was raised by his African-American stepfather, Irving, an acting instructor and theatre manager. He made his stage debut at age seven when he appeared in the children's play Dinosaur Door, written by Barbara Garson. The play was produced at Theater for the New City in New York's Greenwich Village. His involvement in the play came about when he, his brother, and some friends had broken into Theater for the New City's space on Jane Street with the intent to vandalize it. They were confronted by the theater's artistic director, Crystal Field, who, instead of calling the police, handed them scripts and offered them parts in the upcoming show. He remained involved with the theatre throughout adolescence, going on to attend the city's Hunter College, where his creative writing studies led him to begin screenwriting. Diesel became an active film-maker in the early 1990s, first earning notice for the short film Multi-Facial, which was selected for screening at the 1995 Cannes Festival. Diesel has identified himself as a "multi-faceted" actor as a result of early difficulties finding roles due to his mixed heritage.
