There are many legal categories of homicide that overlap with each other. These include murder, voluntary manslaughter and involuntary manslaughter.
The UN Office on Drugs and Crime (UNODC) writes 464,000 people worldwide died from homicides in 2017, with 89,000 killed in armed conflicts. This means 5 times more people died that year globally as a result of homicide than war and terrorism combined.
FBI estimates show the US had 394 violent crimes per 100,000 people in 2018, down from 397.5 in 2016. Nationwide, there were 17,284 murders and non-negligent manslaughters, for a fall of 1.45 percent from 2016.
