According to the anime, at what age is someone eligible to become a Pokémon trainer?

This age can vary slightly from game to game. Children younger than the required age have been shown to own Pokémon, so many fans suspect that younger people can raise Pokémon without a Pokémon Trainer's license, they just can't participate in competitions.
