The insurgents are the Iraqi people which are comprised of many different religious persuasions. Al Quaeda can't be quantified because no one really knows who is a member or acts on a specific directive. The stats being offered in this thread have no evidencial substance because those doing the punditry have not been in Iraq for any length of time or at all. The best sources on Iraq are not the AP or the right-wing megaphone. There are some reliable sources who have written news based on their experience either as Iraqis or those who have observed the carnage first hand. These are few.

Mostly what Americans and Brits hear are propagandized stats and polemics based on flawed international policies such as violent coercion and ideological short-circuits. When someone rambles on about what they think they know, it is most certainly suspect as to its accuracy.
