As you know, the Imperium has never been able to take a census ...


very interested to see what numbers come up :-)

as a broad suggestion, if you can put rough numbers on the number of
computers, and the number of users in the world, then that would help 
to establish a ball-park.

netcraft counted debian as 25% of linux servers in 2005, and were 
counting somewhere around 450,000 of them in 2004.

numbers in the 5-10% ballpark are often wheeled out for linux market

somewhere between 100 million and 10 billion people on the internet ...

1 million doesn't seem like an implausible number.

of those, there are 247 people on #debian right now :-)
as well as numbers for things like mailing list subs.
