So, using the stats around the top 23 industrialized countries, the US has per capita below average crime and is in the lower 3rd section. Canada just missed out of being in the Top 3rd, but has above average crime, per capita.
Out of 23, Canada is ranked 9th and the US is ranked 16th. Lower is better. We have 300 million people in the US, compared with 33 million for Canada.
