Uber on Thursday (December 5) said it received more than 3,000 reports of sexual assault - including rape - in the U.S. last year.
It's the first time the ride-hailing firm has released this kind of data.
Uber said the 84-page report was aimed at showing its commitment to transparency.
They pointed out that over the last two years, 99.9% of their billions of U.S. trips had ended without any safety issues whatsoever.
Chief Executive Dara Khosrowshahi tweeted, "I suspect many people will be surprised at how rare these incidents are; others will understandably think they're still too common.
Some people will appreciate how much we've done on safety; others will say we have more work to do.
They will all be right." Uber has come under increasing pressure from regulators around the globe.
London recently pulled its license to carry passengers over a "pattern of failures" on safety and security.
Over the past couple of years, the company has tried to respond to concerns with new safety features.
Thursday's report seemed to hint that things were improving.
It noted a 16% drop in the most serious sexual assault incidents compared to the year before.
The company also said that roughly half the people accused of assault were actually not the drivers but rather, the passengers.
The data only covered rides within the U.S. So far, Uber's not saying whether it plans to release similar reports for the 70 or so other countries in which it operates.
