From a South Korean news article (translated using llm):

> The police installed human-sized holograms in this park last October. The videos played daily from 7 PM to 10 PM. Analyzing crime occurrences for eight months until May of this year, it was found that the number of major crimes (murder, robbery, rape, theft, violence) within the park's radius decreased by about 22% compared to the same period before the installation (October 2023 to May 2024). This park was a place with frequent reports due to drinking, alcohol-related violence, and disturbances.

Numbeo is entirely based on self-reports by the kinds of people who use Numbeo. For price comparisons you can at least argue that although the prices listed are much too high, it's a realistic representation of how much you're likely to pay if you're a naive Westerner who interacts with locals mainly in English and isn't particularly price-sensitive. But the crime index is entirely based on how worried people are about crime. Considering that most people won't personally become victims of a crime in a given year even in relatively high-crime areas, the crime index tells you more about the people doing the self-reporting than about the level of crime.
