People with disabilities are sorely lacking in representation both on screen and behind the camera, according to a new report funded by the Ford Foundation.

The Road Map for Inclusion report, released Wednesday, details how few disabled people are seen in movies and on TV and calls for proportional representation going forward. That means there should be 1 in 4 people both in front of and behind the camera with disabilities which would match the 1 in 4 adults in the U.S. who live with a disability , according to the Centers for Disease Control and Prevention.

People need to see themselves. People with disabilities, like any other group when you dont see yourself, you feel invisible, said Judith Heumann, a Ford Foundation senior fellow and lead author of the report. Heumann, who had polio at a young age and uses a wheelchair, has been a disability rights activist for decades.

The [entertainment] industry needs to say we have not been doing a good job, we need to do more, she told HuffPost, adding that when discussing the need for diversity, industry leaders should ensure that people with disabilities are a part of that.

The new report pulls out several statistics showing the lack of disability representation in TV and cinema. For example, only 2.7 percent of characters in the 100 highest-earning movies of 2016 were depicted with a disability, per a 2017 report from the University of Southern Californias Annenberg School for Communication and Journalism. Among regular characters on primetime TV in the 2018-2019 season, only 2.1 percent had disabilities , per a report from queer rights group GLAAD.

Heumann noted that disability representation means including people with visible disabilities like those who are blind or deaf, have muscular dystrophy or amputations and also people with invisible disabilities like lupus, epilepsy, chronic pain conditions and more.

The report dives into the stereotypes of disabled people that are often portrayed on screen and makes recommendations for how the TV and film industry can remedy the lack of representation.

Its important because theres a lot of stigma involved with disability, Heumann said. We want media to be able to reflect the diversity of the disability community.
