According to a new report, video game companies are failing to employ a sufficiently diverse workforce, despite increasing demand among employees to hire more women and minorities.

In the International Game Developers Association’s 2017 Developer Satisfaction Survey, released today, 81 percent of game developers said that diversity in the workplace is “very important” or “somewhat important,” up from 78 percent in 2016 and 63 percent in 2015.

Only 42 percent of respondents said the game industry has increased diversity over the past two years, a decrease from 47 percent in 2016.

When asked to choose a single factor that could ensure future growth and success in gaming, 21 percent opted for “more diversity in game content,” just behind “advancement in game design” at 22 percent.

Among full time employed respondents, 14 percent reported that their company had no policies directed toward diversity or equality. An additional 25 percent did not know if their company had diversity-related policies. Among game developers whose employers have diversity and equality policies, only 56 percent said that those policies were being adequately enforced.

In terms of ethnicity, 61 percent identified themselves as white, 18 percent were East/South East Asian (a higher than previous number of respondents were from Taiwan), followed by Hispanic or Latino (5 percent). Black/African American or African made up just 1 percent. 42 percent of respondents were from the United States.

On gender and gender identity, the report states the following:

“Survey respondents were predominately male (74%). Only 21% identified as female, 2% identified as male to female transgender and fewer than 1% identified as female to male transgender. An additional 2% selected ‘Other’ as their response.”

In terms of sexual orientation:

“81% of respondents identified as heterosexual, 5% as homosexual, 11% as bisexual and 3% as other.”

The survey was taken by 963 respondents from around the world, with 42 percent based in the United States, followed by Taiwan, Canada and Australia.
