I've not discarded them, it's just the the largest portion of data for where people in the US are, which NYC has an objectively good per capita murder rate compared to where most people live in the US. If we want to get data for the US as a whole, please point me in the direction where we can find the safety level of the median person, besides NYC having a 3.3 murder per capita rate while the US is ~6.5. Idk what % it is, but a large portion of Americans live in those lists of 100k+ cities.
