At PPW 2007 I have a keynote about Skud's demographic Perl Survey (the domain has sadly lapsed). To illustrate the findings, I did an informal survey of the audience. Fortunately JCap caught it all on film^H^H^H^Helectrons.
First, as a control, I had everyone in the room stand up. Its well known that unless you're Jason Webley you'll never get 100% participation from the audience. So this provides a baseline to compare later measurements against.
As another baseline, we measured those who took the Perl Survey to have some way to compare this set with the set of people who took the survey.
Then I had just the white males stand up. If you visually swap back and forth between that picture and the one of everyone you see there's not a whole lot of difference.
Here we have everyone who is not white and male. Big difference.
And finally a surprising result, those who started Perl during the .com boom. I don't recall exactly what we specified that range as, but it contradicted the data in the survey which shows a big hump during the .com boom.
So there it is, for posterity.
