加拿大有个研究？哪个研究？放狗找了一下，你的“研究”实在不靠谱。

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]

• I was talking about 60s, and you are quoting 70s, who's不靠谱？ -pigletto- ♀ (152 bytes) () 08/21/2012 postreply 15:06:24

• 当然是你不靠谱。你用的是所谓“violent crime”，我用的是homicide。前者历来不准，后者偏差很小。 -老忽叔叔- ♂ (95 bytes) () 08/21/2012 postreply 15:14:57

• 人口老年化富裕化一直在发生，别忘了babyboom发生在什么时候。这批人长大是什么时候。要correct可以，七十年代也该cor -老忽叔叔- ♂ (187 bytes) () 08/21/2012 postreply 15:46:35

• 把美国和加拿大homicide rate相比最能说明问题。美国人均持枪88。8％，加拿大30。8％ -老忽叔叔- ♂ (214 bytes) () 08/21/2012 postreply 16:00:06

• 至于把哥伦比亚与美国犯罪率相比简直就是把小猪和老虎相比。但，深一层比，却非常说明问题。哥伦比亚毒贩的枪支就是用来犯罪的，也是哥伦 -老忽叔叔- ♂ (0 bytes) () 08/21/2012 postreply 16:20:19

• 是你要correct数据，号称90年代后的降低是老年化引起，不是控枪的效果。又拿出60年代为基础却不考虑60年代的demogra -老忽叔叔- ♂ (146 bytes) () 08/21/2012 postreply 16:11:43
