Here's why:
* Disney Channel features actors of various ages: They cast actors in shows for a variety of age ranges, from pre-teens to young adults.
* Shows have different age groups: Some shows target younger audiences, while others are aimed at teenagers. This impacts the ages of the actors.
* Age isn't the only factor: Disney Channel considers talent, personality, and suitability for the role when casting.
So, while there might be some 9-year-old Disney Channel stars, there are also many stars of other ages.
