Twitter, the San Francisco-based company which makes a global information-sharing network, released workforce data to illustrate the company’s diversity. Or lack thereof. 

The numbers don’t look much different from its tech company counterparts, but the biggest disparity lies in the people who work in technical roles at Twitter. Nine out of ten Twitter engineers are male.

That’s slightly higher than at Facebook and Yahoo, where the technical workforces are 85 percent male.

Globally, 70% of Twitter’s workforce is male. In the U.S., 59% is white, 29% is Asian, and 2% is African American. 3% identify as Hispanic or Latino.

For comparison, the U.S. population is 62.6% white, 17.1% Hispanic or Latino, 13.2% African American, and 5.3% Asian. 

For years, it’s been well known that Twitter is disproportionately popular among African Americans. A Pew Research Center study found that 18 percent of Twitter’s U.S. users are African American—a higher percentage than on Facebook or LinkedIn.

To Twitter’s credit, it acknowledges that not all is well with these numbers.

“We have a lot of work to do,” Janet Van Huysse, Twitter’s vice president of diversity and inclusion, wrote in a blog post
