The 2015 edition shows that diversity on screen is almost exactly the same as it was in 2007.
(In 2007, that number was 29.9 percent, and its stayed almost exactly the same since.)
As for lesbian, gay, bisexual, or transgender characters?

Thats slightly better than last year, when there were only 19 characters.
And although the study found zero transgender characters in 2014, this year, they found one.
The study also found that there isnt just a lack of diversity in front of the camera.
