Even murder statistics aren't foolproof when comparing crime rates across different countries and time periods, because of differences in medical care standards

Even murder statistics aren't foolproof when comparing crime rates across different countries and time periods, because of differences in medical care standards. Someone can be shot several times in the modern West and recover, but 200 years ago or in a poor country (or maybe in a more remote location) the same person would not survive and it would count as a homicide.
