I work in IT and keep a website for my DND group, so I got to thinking the other day about what the statistics are of all the characters our 24ish players have made and used in 4e so far... this includes throw away campaigns as well as long lived story arcs. Well I tabulated them up (with some errors) and figured you guys may be interested in some of the breakdowns we've seen in our group. I'll offer a minor explination at the end.
Note: Due to incomplete data the totals for each table wont always match.

---------------
No single person has made more than 26 of the 430 characters I have recorded, a few only made 1 or 2, average character per person is 10.7
As you can see we've done a few Human Only campaigns and PHB1 classes got a lot of love. I generally play Divine, another guy generally plays Primal, and another 2 generally pick up Arcane. Beyond that we dont have much in the way of consistency between the classes people want to pick outside of Roles. As you can tell most of our people dont like controllers much...
the Roles are determined based a combination of class and playstyle. With the Ardent Paladin and some Genasi Wizard builds you can easily hit a striker level damage output and playstyle while ignoring much of the initial role. This is even more notable with the Essentials products and the slayer being a Fighter build, but Striker role - as such the tables attempt to reflect that.
for the Paragon campaigns we've had, Dreadnought, Sorceror, Clockwork Engineer, Frenzied Berserker, Master of the Forge, Radiant Servant, Shadowblade, Warpriest top the list at 6, 5 and 4,4,4,4,4,4 instances respectively out of 115 occurances
For Epic - of the 74 characters in epic or planned through epic- 10 are Demigod/Chosen, 5 Exalted Angel.
Any other stats that anyone would be interested in or would anyone want to tabulate your own?
