The report from Uber focused exclusively on rides in the U.S. and not the 65 other countries where Uber operates, including India, where a driver was sued in 2017 for allegedly raping a passenger. The total number of Uber rides in the United States during the period was 2.3 billion.
The ride-sharing giant said the safety report was conducted with the intent of providing transparency and accountability around its app for both riders and drivers.
Uber first pledged to release the report almost a year ago in response to a CNN investigation that found at least 103 Uber drivers in the United States had been accused of sexually assaulting or abusing their passengers in the previous four years.
In 2017, Uber received 2,936 reports pertaining to sexual assault, and received 3,045 in 2018.
Of these incidents, riders were accused as the perpetrator 45% of the time.
It added that the numbers published in the safety report were largely dependent on victims providing information about their sexual assault.
"During 2017 and 2018, there were 19 fatal physical assaults occurring in a total of 18 incidents in relation to Uber", the company said.
It also detailed 10 fatal physical assaults in 2017 and nine in 2018 - eight victims were riders, seven were drivers using Uber's app, and four were third parties such as bystanders. According to Uber, approximately 90% of Uber-related fatal crashes occurred in urban areas.
Uber and competitor Lyft have faced harsh criticism for not doing enough to protect the safety of their riders and drivers. However, Uber said the trend need not remain this way, as releasing such data may lead to an increase in reporting of such incidents in the future. "And, most importantly, by bringing hard data to bear, we can make every trip safer for drivers and riders alike", the company's Chief Legal Officer, Tony West, said in the executive summary of the report.
He added: "In the long run, we will be a better company for taking this step today - because I firmly believe that companies who are open, accountable, and unafraid are ultimately the companies that succeed". "It's really unprecedented for a company to collect this kind of systematic data over time and then share it with the public", says Karen Baker, CEO of the National Sexual Violence Resource Center, which advised Uber on the study. In 2017, a woman who was raped by her Uber driver in India filed a lawsuit against the company for violating her privacy.
The company has introduced other safety features to combat incidents included in the report, including the introduction of a "panic button" for use in instances of an emergency.
Last month, London refused to renew Uber's license to operate in the city, after reports of safety issues concerning impostor drivers.
