They had 13 in 2014, 21 in 2015. My guess is laid off oil workers and energy economy slowdown have more to do with 8 murders
Small numbers... big percentage fluctuations. I think the numbers might be too small to be statistically significant.
“They had 13 in 2014, 21 in 2015.”
Is that for all of Alaska? The Anchorage numbers at https://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2015/preliminary-semiannual-uniform-crime-report-januaryjune-2015/tables/table-4/table-4-state-pieces/table_4_january_to_june_2015_offenses_reported_to_law_enforcement_by_state_alabama_through_california.xls are 6 and 16. That difference is statistically significant at the p=0.05 level - but for all the reasons mentioned already in this thread, the cause is very much open to question. Also, the same link shows murders in Scottsdale, where pot remains illegal, going from 0 to 3 - an infinite relative increase.
