From the article:
I AM PWD, which stands for Inclusion in the Arts and Media of People With Disabilities, was formed by the Performers With Disabilities Tri-Union Committee of Actors' Equity, AFTRA and SAG in response to the lack of representation on television and film of people with disabilities. Additionally, the campaign covers a dearth of stories that explore issues associated with disabilities.
In 2010, the American Community Survey conducted by the U.S. Census Bureau found that 12 percent (36.4 million people) of U.S. non-institutionalized citizens report living with an apparent disability. The three unions believe that this group — and all Americans — should be able to see their lives and concerns reflected onscreen, and that the media we consume should reflect the American Scene in all its variety.
