"This is GLAAD’s eighth year of tracking number of
series regular characters on primetime broadcast
scripted series who are depicted as people
with disabilities (PWD).
"According to the 2016
American Community Survey conducted by the U.S.
Census, 12.8 percent (40.7 million) of U.S. noninstitutionalized
citizens are living with an apparent
disability. In its count, GLAAD included characters
who would be covered under the Americans with
Disabilities Act (ADA), which includes people living
with non-apparent disabilities such as cancer or HIV
and AIDS. Inclusion of those disabilities would greatly
increase the figures found by the U.S. Census Bureau.
"While the percentage of series regular characters
living with disabilities on broadcast has increased this
year, primetime programming continues to fall short in
reflecting the reality of this demographic.
This year, the percentage and number of series
regulars with disabilities has risen slightly to 1.8
percent (16 characters) from the previous year’s 1.7
percent (15 characters). This is the highest percentage
of inclusion since GLAAD began gathering disability
statistics in the 2010-11 season."
