Who tips on Uber?

Men tip 12 percent more if their driver is a woman, but that’s entirely because they give more money to the youngest female drivers. The premium men pay to women behind the wheel shrinks as the women get older. By the time the drivers are age 65, it has virtually vanished. Women also tip other women more, but they don’t significantly change their tips based on the driver’s age.

Tips are highest between 3 a.m. and 5 a.m., and not surprisingly:

Tips are highest in small cities and the middle of the country. Riders in California and the Northeast weren’t great tippers.

Here is much more from Andrew van Dam at The Washington Post.
