The report covered the safety of both riders and drivers. Murder victims were drivers, passengers and third parties. In cases of rape, Uber said, 92 percent of the reported victims were riders. But drivers reported other types of sexual assaults at roughly the same rate as riders, Uber said.
The company was not specific about who the perpetrators were.
Uber said it had cataloged 2,936 sexual assaults in 2017 and 3,045 in 2018, ranging from unwanted kissing of what it called a “nonsexual body part” to attempted rape and rape. The largest category was nonconsensual touching of a “sexual body part” like someone’s mouth or genitals.
The number of fatal crashes related to Uber trips was 49 in 2017 and 58 in 2018. The statistics included accidents that occurred outside Uber vehicles, such as when a passenger was struck after exiting a ride, and crashes in which Uber drivers were not at fault.
Uber disclosed 10 murders in 2017 and nine in 2018. Seven victims were drivers, eight were passengers, and four were third parties, like bystanders outside the Uber vehicles, the company said.
Throughout its study, Uber emphasized that 99.9 percent of its trips were safe and that it was taking an unusual step by releasing the data in the first place. Sexual violence experts agreed that publishing the numbers was an important step in combating abuse across the industry.
“That a company is willing to peel back the drapes and let us look into what is happening is, to me, the success,” said Cindy Southworth, the executive vice president of the National Network to End Domestic Violence and a member of Uber’s safety advisory board.
Uber began studying the issue of sexual assault in late 2017 under its newly hired chief executive, Dara Khosrowshahi. He recruited Mr. West, a former Justice Department official, to the company and asked him to review cases of sexual harassment and assault among Uber rides that year.
