Editor's Note: In today’s United States, is being black determined by the color of your skin, by your family, by what society says or something else? Soledad O’Brien reports “Who Is Black in America?” on CNN at 8 p.m. ET/PT Sunday, December 15.

(CNN) - Seventeen-year-old Nayo Jones has chestnut colored skin and wears her curly hair in a small Afro, but she doesn't "feel black".

“I was raised up with white people, white music, white food, so it’s not something I know,” says Jones.

She sits in a circle talking about black culture and what makes someone black in 2012, surrounded by a group of diverse teens and twenty-somethings. They grew up with a biracial president who identifies as black.  They will not have to fill out a census that demands they check just one racial box. And they are part of a generation that has a growing number of mixed-race relationships and people.

In 2010, 15 % of new marriages were between people of different races or ethnicities, double the number from 1980. Also, the number of people who self-identify as mixed race is growing.

For Jones, who has a black mom, but was raised by her white dad, black requires a certain type of experience. She rejects identifying as black because, “It's kind of my lack of the black experience, or what other people would say is my lack of a black experience.”

Many of the 50 or so young adults in the room view race differently from their parents, and from one another. For them, race is fluid, and they get to decide their identity. FULL POST
