No, anime is [i]watched by[/i] young adults in America. It's [i]made for[/i] children in Japan. There are animated shows with art styles heavily influenced by anime from other parts of the world, and wether or not they should be considered anime is a subject of a great deal of debate. Personally, I'm in the camp that says animation is animation and it's stupid to categorize it by country of origin, though it can be useful to recognize similar stylistic choices.
