I'm not affiliated with jobs.perl.org, and this is only the simplest of analyses. I didn't try to correct for duplicate posts where the same job was re-advertised. jobs.perl.org has their own stats, although Dave Rolsky seemed to think my numbers might be better. I don't know if I believe him. :)
I don't attempt to draw any conclusions about the popularity (up or down) of Perl from these numbers. In general, I think that the continual uptrend is more about people finding out about the free service than the same market having more jobs.
I made this same report in 2006 too, and there are some interesting links in the comments. Also interesting is renodino's graphs about jobs on Dice and the code he wrote to make them, along with the discussion about the usefulness of any conclusions.
