Let's try talking apples and apples, since trying to make this about France "density" vs U.S. "density" is pretty much irrelevent when the sizes of each country is applied. How about New York with Paris, or Washington DC with Paris......or some equivalent populated U.S. city with Paris. Ball in your court, and we'll go from there
Oh dear Lord!
Sirs, you studied biology in school, right? Density and rate are units of measurement that are comparable across the board. They put the nations on an equal footing and are hardly "irrelevant."
OK.
Paris had 181 homicides between 1998 and 2001. That gives them a rate of 2.85 per 100,000 for the same time period according to a Home Office
document produced by the British Government comparing EU capitals.
In that same time period New York had 1,977 homicides, or a rate of 8.77 per 100,000 for the period of 1998 to 2000. Washington D.C. had 733 homicides or a rate of 45.79 per 100,000 for the same period.
The same report (page 10) shows that compared to Europe (including Turkey) and a few non-European states the United States homicide rate is better than only a few countries which are:
Russia
South Africa
Latvia
Lithuania
Estonia
We aren't even comparable to another European country, including Northern Ireland.
