Here's Nation Master's collection of mortality statistics; remember I promised to look up comparative domestic accident death rates, and found a lot more. Looks like here they've got rankings of almost everything.

Just a few examples (all statistics deaths per 1 million people per year, as of 2004):

Alcoholic liver disease: 1. Hungary 498; 6. Germany 127; 17. US 41; 30. Spain 27; 44. UK 14.

Assault with sharp object: 1. Colombia 72; 36. US 6; 44. Spain 4; 52. Germany 2; 56. UK 1.

Assault with handgun: 1. Dominican Republic 16; 8. US 4; Spain, Germany, UK all less than 1.

Car occupant collision with another car: 1. Hungary 39; 6. Spain 27; 15. US 17; 26. Japan 8; 30. Germany 6; 37. UK 1.

Diarrhea and gastroenteritis, presumed infectious: 1. South Africa 178; 27. Japan 8; 30. Spain 6; 37. Germany 2; US and UK less than 1.

Drowning: 1. Latvia 138; 10. Japan 63; 47. Spain 20; 50. US 15; 53. Germany 13; 61. UK 2.

Motorcyclist, collision with car: 1. Bahamas 13; 3. Japan 7; 10. Spain 5; 20. Germany 3; 21. US 3; 39. UK less than 1.

Obesity: 1. Austria 27; 5. US 10; 7. Germany 8; 8. Spain 8; Japan and UK less than 1.

Self-harm: 1. Lithuania 417; 7. Japan 215; 20. Germany 112; 27. US 82; 30. Spain 77; 57. UK 7.

Remarks: Looks like you're more likely to be murdered in the US and more likely to die in a road accident in Spain. You're about as likely to die of infectious diarrhea or gastroenteritis in Spain as you are to be shot with a handgun in the US. And what do people in the UK die of? Looks like we have to take these figures with a shaker or two of salt, too, since different countries obviously use different standards when they classify causes of death.

Conclusion: When you start to take many factors into account, and considering that our figures are not completely reliable, it's difficult to say that Country X is more dangerous than Country Y. Probably the best indicator of how likely you are to die in one place rather than another is life expectancy, and all Western countries are between about 75 and 81 years. That is, if you're Spanish and you go to the States for a year, or to Japan, or to England, your probability of dying during that time is most likely nearly exactly your probability of dying if you'd stayed in Spain during that year.
