Uber released its first employee diversity report this week, and while Uber's reputation is particularly strained at the moment, its workforce demographics aren't all that different from those at other tech companies. White and Asian men still dominate the ranks of major tech companies.

Why it matters: Lack of diversity — particularly for women, African American and Latino workers — is a systemic problem that Silicon Valley companies have actively tried to address. Despite these efforts, these firms have made only modest improvements in recruiting these under-represented workers for key technical and management jobs.

Methodology: Axios used government EEO-1 reports filed by the companies that shows the racial and gender breakdown of their U.S. employees. We used "Professional" employees as a proxy for technical jobs, though the category does include other professions like accountants and lawyers.
