According to Louie Crew, only 71 deputies out of 1021 elected deputies to TEC’s General Convention are under 40. That is roughly 7%. Almost insignificant, statistically speaking. Only 16.2% are in their forties, so you are then talking a mere 21% or so being under 50. UNDER 50!
There are also more lawyers at GC2009 than people under 40, which is really bad considering that more than half the deputies have to be clergy. Considering that the Episcopal Church is usually considered to be a predominately Caucasian bunch (to say it mildly), yes, there are 8 more African American deputies than there are deputies under 40.
