I just wonder...

...how they get to those numbers. If I would copy a piece of software I wouldn't run around telling everybody - so how do they know that X percentige of software is pirated?!

...but 93.576% of all statistics are fake anyway ;)

Correlations

Maybe there is a correlation that in some asian countries a standard windows home edition license costs more than 2 monthly wages.
There also could be a correlation that where software piracy is the highest, the skill level of computer experts is highest since they can just go ahead and learn any kind and number of programs without the BSA breathing down their necks.
Heck most of them is happy if they can buy food after paying all taxes, not sending their money to some american megacorporation.

$14 billion ? Sure.

The official market price for Vista in China is what, around $70, and Chinese employees average apparently $3550 a year.
That makes for a hair less than $300 a month to live with, which is around $75 a week.
Okay, those who can spend a week's salary on an OS without budget problems raise their hands.
Apart the gas-guzzling SUV drivers, I don't think I'll see many hands raised, and I don't think it's any different in China.
More than anywhere else, China is a place where, if they can't have it via piracy, they simply won't use it.
So BSA can crow about lost sales all it wants, the truth is they should be happy about having any sort of presence at all, because if Chinese users couldn't get their hands on a pirate copy, Windows would still mean something you shut to stop the drafts.
