The fact that the US is an extremely violent place in which large numbers of people appear to drive like maniacs does indeed reduce the life expectancy. In comparison to most of the countries in the report you link to, the difference is worth, as you say, the best part of a year – up to 0.8 assuming 40,000 extra deaths per year and average age of death in murder/car crash of 25.mheslep said:Run the numbers yourself instead talking about what you suspect. If one assumes the average age of the homicides and car wrecks is 25, by itself that moves the longevity of the entire US population down by nearly year, and we only talking about a couple years of difference.

However, that is not what table 1-5 says. It makes the swing in difference due to fatal injuries between Japan and the US 4.3 years. Now, perhaps unsurprisingly, they don't show their workings in that report. Could that be because they've made their figures up?
It would mean not 40,000 extra deaths per year, but 220,000. Given that about 60,000 people are murdered/die in car crashes each year in the US, this must mean that 160,000 (adjusted for size of population) are resurrected in such incidents in Japan each year. I haven't checked Japan's latest figures, but I doubt this is correct.
BTW I'm assuming you've abandoned your third criterion, genetics? This is a science forum after all. I'm also not quite sure how the murder/road death rate affects infant mortality, in which the US performs very poorly. Are mothers going into labour on the road, perhaps? I can see how the distraction of childbirth might cause them to crash.Facetiousness aside, beware internet 'reports' of dubious provenance. They are likely to be full of crap.
