A 2012 study looked at gun control laws passed in Canada from 1974 to 2008 and found no evidence that these laws had a beneficial effect on firearm homicide rates in that country. According to the study, "other factors found to be associated with homicide rates were median age, unemployment, immigration rates, percentage of population in low-income bracket, Gini index of income equality, population per police officer, and incarceration rate."
