Comparison of homicide statistics of 9 different countries[citation needed]
Comparing crime rates between countries is difficult due to the differences in jurisprudence, reporting and crime classifications. National crime statistics are in reality statistics of only selected crime types. Data is collected through various surveying methods that have previously ranged between 15% and 100% coverage of the data. A 2001 Statistics Canada study concluded that comparisons with the U.S. on homicide rates were the most reliable. Comparison of rates for six lesser incident crimes was considered possible but subject to more difficulty of interpretation. For example, types of assaults receive different classifications and laws in Canada and the US, making comparisons more difficult than homicides. At the time, the U.S. crime of aggravated assault could be compared to the sum of three Canadian crimes (aggravated assault, assault with a weapon, and attempted murder). This comparison had a predicted bias that would inflate the Canadian numbers by only 0.1%. The study also concluded that directly comparing the two countries' reported total crime rate (i.e. total selected crimes) was "inappropriate" since the totals include the problem data sets as well as the usable sets.[15] For reasons like these, homicides have been favored in international studies looking for predictors of crime rates (predictors like economic inequality).
United States
Much study has been done of the comparative experience and policies of Canada with its southern neighbour the United States, and this is a topic of intense discussion within Canada.
Historically, the violent crime rate in Canada is lower than that of the U.S. and this continues to be the case. For example, in 2000 the United States' rate for robberies was 65 percent higher, its rate for aggravated assault was more than double and its murder rate was triple that of Canada. However, the rate of some property crime types is lower in the U.S. than in Canada. For example, in 2006, the rates of vehicle theft were 22% higher in Canada than in the US.[16] Since violent crimes are a smaller fraction of all crimes, the difference between the two countries is less than the homicide rate might make it seem, and the overall rates are generally close (see Crime in the United States).[citation needed]
Furthermore, in recent years,[when?] the gap in violent crime rates between the United States and Canada has narrowed due to a precipitous drop in the violent crime rate in the U.S. For example, while the aggravated assault rate declined for most of 1990s in the U.S. and was 324 per 100,000 in 2000, the aggravated assault rate in Canada remained relatively steady throughout and was 143 per 100,000 in 2000. In other areas, the U.S. had a faster decline. For instance, whereas the murder rate in Canada declined by 36% between 1991 and 2004, the U.S. murder rate declined by 44%. [17] Both Saskatoon and Regina consistently have violent crime rates that would place them among the 10 most violent cities in the US, and often individually exceed larger US centres in terms of total numbers for Aggravated Assaults and Robbery.[citation needed]
The homicide rate in Canada peaked in 1975 at 3.03 per 100,000 and has dropped since then; it reached lower peaks in 1985 (2.72) and 1991 (2.69). It reached a post-1970 low of 1.73 in 2003. The average murder rate between 1970 and 1976 was 2.52, between 1977 and 1983 it was 2.67, between 1984 and 1990 it was 2.41, between 1991 and 1997 it was 2.23 and between 1998 to 2004 it was 1.82.[18] The attempted homicide rate has fallen at a faster rate than the homicide rate.[19]
By comparison, the homicide rate in the U.S. reached 10.1 per 100,000 in 1974, peaked in 1980 at 10.7 and reached a lower peak in 1991 (10.5). The average murder rate between 1970 and 1976 was 9.4, between 1977 and 1983 it was 9.6, between 1984 and 1990 it was 9, between 1991 and 1997 it was 9.2 and between 1998 and 2004 it was 6.3. In 2004, the murder rate in the U.S. dipped below 6 per 100,000, for the first time since 1966, and as of 2010 stood at 4.8 per 100,000 [17]
Approximately 70 percent of the total murders in the U.S. are committed with firearms, versus about 30 percent in Canada.[20]
