User blog:TVthePunisher/Character Ages - If it's not stated show-wise, let's consider the actor.

Thankfully in the case of the Dexter universe, characters aren't aged based on the role mostly. All of the actors are within the expected ages for the characters and in some cases, when birthdates are shown on screen it typically is the actual actor or actress's birthday they're using.

So...I'm wanting to move away from this "30's" and so on generalization for characters we don't know birthdays on. Thankfully information such as provided via http://www.sho.com/site/dexter/killroom.sho give us insight onto various character's ages for victims that have crossed Dexter's path...but there are still a lot of other characters that need some sort of age.

Here's what I propose: If the show does not have any physical evidence to show a character's age such as a criminal file, a birth certificate, some sort of documentation or hell word of mouth...we should consider the actor's age (if provided and whether or not it can be found) and use this. Thankfully, most of the characters without an age now are minor regardless...all of Dexter's shown victims have an age, most of the main characters have confirmed ages. Let's get started on this.
