The report showed that about 92% of the victims of rape were riders and about 7% of the victims were drivers. Women and female-identifying individuals made up 89% of the victims with men and male-identifying individuals comprising about 8% of victims. Fewer than 1% of victims identified as gender minorities.

The other four categories of sexual assault defined by Uber — including non-consensual kissing, non-consensual touching and attempted rape — did not detail whether the reporting parties were victims.

The new 84-page report contained data that Uber had from 2017 and 2018, and included incident reports resolved on or before October 31, 2019.

Uber announced increased safety measures in 2018, including a partnership with RapidSOS, a company that sends a rider's location and relevant information to a local police agency when the rider uses the emergency button in the Uber app. Uber also revamped its background check policy to conduct annual checks on drivers. Uber ultimately announced it would do away with a policy that previously forced individuals with sexual-assault complaints into arbitration and made them sign non-disclosure agreements.

"The public responses to this transparency report or similar public reporting of safety incidents claimed to have occurred on our platform ... may result in negative media coverage and increased regulatory scrutiny and could adversely affect our reputation with platform users," the company says in the filing.

Uber and competitor Lyft have faced legal action related to safety issues around the country. A lack of transparency about the number of incidents involving drivers has been a sticking point in lawsuits against the company. Lyft has also said it will release a safety report by the end of the year.

Safety issues with ride-hailing apps aren't limited to domestic companies.
