While there are surveys and public polls on what cities in a state are the safest, we didn't want to rely on speculation and opinion. Instead, we looked at the hard numbers from the FBI's most recent report of crime (Sept 2017) in Idaho.
Specifically, we analyzed the FBI's Uniform Crime Report which summarizes the number of property crimes and violent crimes in each city per year. We used two criteria:
Violent crimes per capita (murders, assaults, rapes, armed robberies)
Property crimes per capita (thefts, burglaries, motor vehicle thefts)
For example, there were a total of 198 crimes committed in Rexburg which had a reported population of 28,112. That means the number of crimes per capita is 0.007 which translates into a 1 in 141 chance of being the victim of a crime.
We only looked at cities that have populations of more than 5,000 people reported to the FBI in 2016. This left us with a total of 26 of the biggest cities in Idaho to rank.
We ranked each city for each criteria from 1 to 26 where 1 in any particular category is the safest.
Next, we averaged each places two criteria to create a Safety Index. We crowned the place with the lowest overall Safety Score "The Safest Place In Idaho".
The safest city, based on our criteria, is Rexburg. The most dangerous city in Idaho? Garden City, where residents had a 1 in 23 chance of being the victim of a crime.
Note: This report is not an analysis of the effectiveness of local police departments, nor does it reflect the fact that people from out of town may come into a community and cause a crime. It simply looks at where crimes occurred most frequently, based on a city's population.
