In the future, it may be helpful to remember that murder and violence — especially sexual violence — are oddly intimate things,

    In 2011, in incidents of murder for which the relationships of murder victims and offenders were known, 54.3 percent were killed by someone they knew (acquaintance, neighbor, friend, boyfriend, etc.); 24.8 percent of victims were slain by family members.  The relationship of murder victims and offenders was unknown in 44.1 percent of murder and nonnegligent manslaughter incidents in 2011.

In short, people were killed by strangers 11.7% of the time. For 88.3% of murders (where the relationship between the killer and the victim was known), it was someone the victim knew.

The statistics are similar for sexual violence.

For juveniles and children who experience sexual violence, it is a family member of acquaintance 93% of the time. This percentage drops for adults to ~80%, i.e. in 80% of cases the victim will know the perpetrator.

These crimes are very different from a mugging or robbery. It is easy to imagine why if you replay the situation in your mind — looking someone in the eyes as you stab them, up close takes a lot emotionally. It is a very intense situation. Almost everyone — if driven to it — will steal out of desperation and hunger, but very few can look people in the eye, walk up to them and stick a knife in them. There is a strong psychological aversion to hurting other human beings built into most of us and it's what keeps society mostly safe.




Nit, but I think that 24.8% is a subset of the 54.3%, not additive - i.e. “family members” are included in the category of “people you know.”

(Confirmed with the pie chart in your first link.)


Great nit! I'll update it to the actual state i.e. only 11.7% of people are killed by strangers. 88.3% knew their killers in some capacity.
