More than 8 in 10 American grown-ups say they believed in Santa when they were children. And they're keeping the tradition alive.

An AP-GfK poll finds that two-thirds of parents with kids under 18 consider Santa Claus

an important part of their holiday this year.

In multicultural America, Santa isn't just for Christians. Three-fourths of non-Christian adults believed in Santa when they were tots, and half feel he's important to their seasonal celebrations now.

The median age when adults say they lost touch with Santa's magic? 8 years old.
