I was looking at life expectancy stats as part of a discussion here and came across this chart:
One thing that really stuck out is how steady life expectancy has been over the last seventy years -- there's been a gradual improvement, with no big gains or losses in any given year. Part of that is related to the size of the country. The bigger it gets, the more that localized events like Hurricane Katrina or 9/11 get averaged out to the point they don't show up. But there's a lot more going on than that. The CDC was founded in 1947 and that likely made a big difference, along with various other governmental programs designed to control disease (Polio vaccination, anti-Malaria efforts in the late 40s and early 50s, etc.) As much as we worry about crime waves, natural disasters, and terrorists, disease is the kind of killer that can actually take out enough people to impact life expectancies in a noticeable way in the big picture. If you look at chart above, you're unlikely to be able to spot the wars in Korea and Vietnam, by the shape of the chart, much less various terrorist incidents or smaller wars. But you'll spot the flu pandemic of 1918 very easily.
