The US is also an outlier in terms of murder rate compared to poor countries. The Us homicide rate is over 6 per 100k, while Pakistan (which has plenty of guns) is under 4. But the US isn’t really one place. Idaho’s homicide rate is 2.2, while Puerto Rico’s is 19.3. Which is 5 times higher than Afghanistan. Note that Spain’s homicide rate is under 1. Puerto Rico and Spain actually have similar GDP per capita. And Puerto Rico is an island with strong gun control.
