Methodology:
All data was sourced from the Federal Bureau-Investigation's Uniform Crime Reports. Crime reports for 2016 are not included in this data visualization, because the FBI only has its preliminary semiannual uniform crime report listed for the year, from January to June.

The crime rates, for both property and violent crime, were calculated by taking the number of reported property (or violent) crime incidents per location, dividing this by the location's population, and then multiplying by 100,000. This produces a property (or violent) crime rate per 100,000 people.

Unlike the similar article, DATA VIZ: Safest cities in Alaska this set of data examines the state of Alaska, as a whole. This set of statewide data also analyzes the trends of specific types of crime, instead of the specific locations that crime occurs.

Minor differences in violent crime rates, between KTUU's calculated rates and AJSAC's calculated rates, stems from using slightly different state population figures. KTUU staff calculated rates using population information as provided by the FBI and UCR.

Story:
University of Alaska's Alaska Justice Statistical Analysis Center (AJSAC) released its Violent Crime Reported in Alaska, 1986 - 2015 fact sheet, on Feb. 20. They sourced their data from the Alaska Department of Public Safety's Crime in Alaska annual report.

According to AJSAC, "From 1986 to 2015, the rate of violent crimes reported to police averaged 602.8 per 100,000 residents per year." During this time period, the violent crime rate in Alaska increased; whereas, from 1960 to 2015, the rate of total violent crimes reported to police only averaged 502 per 100,000 residents per year. Both of these averaged rates are higher than the national 1960 to 2015 averaged rate of 471.2 per 100,000 residents in the U.S. per year.

In terms of property crimes reported, from 1960 to 2015, Alaska's averaged property crime rate, at 3,968.6 per 100,000 Alaskan residents per year, was also greater than the national averaged rate, at 3,791.9 per 100,000 people.

Additionally, in 2015, Alaska's violent crime rate, at 730.2 violent crimes per 100,000 people, was 1.9 times greater than the national crime rate, at 372.6 violent crimes per 100,000 people. While Alaska had high rates of robbery and rape (revised definition), it was the rate of aggravated assault that significantly contributed to driving this number upwards.

In 2015, Alaska's property crime rate, at 2,817.6 crimes per 100,000 people, was 1.1 times greater than the national crime rate, at 2,487 crimes per 100,000 people.

In Alaska, between 1986 to 2015, AJSAC says that the rate of aggravated assaults, at 432.3 per 100,000 people increased, the rate of robberies, at 89.7 per 100,000 people decreased and the rate of rape, at 85.7 per 100,000 increased.

Whereas, compared to the averaged rates between 1960 to 2015, all of the violent crime category types saw increased rates.

Take a look at the interactive data visualization, above, to examine how else Alaska's rates of violent and property crimes, by specific type, compare to the past.
