A note on methodology: I went through all five books (seven, in the UK editions) and made a note of every single time someone died, had sex, got married or was executed. I also tried to concoct an ultimate master-menu of every bit of food mentioned by GRRM in the novels, which caused my computer to crash and caused an Internet black-out covering much of the western half of Europe*. I also counted the number of times popular phrases (yes, even "Words are wind,") and unusual words ("Nuncle," natch) cropped up.
There was a lot of judgement calls in this. If GRRM describes someone getting smashed in the face by a mace and then ridden over by a horse into the mud, it's probably safe to assume he's dead. Someone with their hand cut off and is surrendering with the possibility of medical aid (if of uncertain quality; no Talisa in the books, remember) is a bit less certain and thus was not counted. The deaths include reported, accurate figures, such as the roll-call of how many knights and lords died on the Blackwater (the peasant soldiers were less lucky, obviously), and some prominent off-screen but reported deaths. Rumoured deaths which are not backed up by strong argument, and where strong theories suggest the person survived, were not counted. The death count also includes prominent animals (like certain direwolves) but not every dragon-roasted sheep or messenger raven shot down. The weddings count also includes off-screen weddings (Bronn and Lollys) and very minor ones (Tyrek and his toddler-bride).
I haven't seen these before, so I have no idea what's going to be on the next two.
