I have been promising (or threatening, depending on your point of view) for some time to write on the subject of SEG's demographics and now is the time. One could say that it is SEG's most important issue because our demographic profile says a lot about our society and deeply influences our future. Yet, I have been slow to bring the issue to the fore because I have been puzzled by some aspects of our demographics and also needed to collect some hard data. I think you may find the results interesting.
