A report released by the Crime Prevention Research Center (CPRC) says there is a "geographical concentration" of murders in only 5% of counties.
CPRC President John Lott says the data is stunning.
"We show that even within these counties, with all these high rates, murders are very concentrated...these high [rate] counties have very large areas where there are no murders.”
The data says in 2014 the US murder rate was 4.4 per 100,000 people and if the deadliest 5 percent of the counties weren't counted, the rate would drop to 2.56 per 100,000 people.
Last year, more than half the murders occurred in the country happened in only 2 percent of counties.
Los Angeles County had 526 murders in 2014, but places like Beverly Hills, Hawthorne and Van Nuys had almost none.
In Washington DC, large portions had no murders period and if they were it was concentrated to the eastern half of DC.
