According to a report by the California Film Commission, the animation industry in California contributes over $18 billion to the state's economy annually. This significant economic impact is a testament to the industry's vibrancy and success.

The presence of prestigious educational institutions such as the California Institute of the Arts (CalArts) and the University of Southern California (USC) School of Cinematic Arts has also played a crucial role in nurturing talent. These institutions offer specialized programs in animation, providing a steady stream of skilled professionals to the industry.

Additionally, California hosts numerous industry events and conventions, such as the Animation Expo and the SIGGRAPH conference, which attract professionals from around the world. These events serve as platforms for networking, collaboration, and showcasing new talent and technologies.

In New York, the animation industry is also robust, particularly in the New York City area.
