There's this: "The suit cites data from a 2015 review of Google’s employment practices by the U.S. Department of Labor’s contract compliance unit that’s the subject of a separate federal administrative complaint against the company. The agency performed a statistical regression analysis of the pay for roughly 21,000 employees at the company’s Mountain View office for 2015, according to the complaint. The analysis “found systemic compensation disparities against women pretty much across the entire workforce," according to the suit." Obviously not specific to these 3 women, but it does seem to be based on "data" and not anecdotes.
