Memphis had 63.9 homicides per 100,000 people in 2023.
I don't have stats for individual Chinese cities, but China's rate is 0.46 per 100,000 people. In China, it's plausible that the cities are safer than the countryside, and I don't think that Beijing's number is substantially higher than the national average.
Basically, you are 139x more likely to be murdered in Memphis.
