According to AMA Education Director Bill Pritchett in his Nov '13 AMA News column, youth membership has grown from 11,000 (Jun 2010) to to 45,000 at last count. So yes, membership is growing and it's great that it is mainly in the youth sector. OTOH, if Open membership has only stayed steady through replacement keeping up with attrition since 2010, current ('13) membership would be abt 174,000. Wanna bet the tally will approach that figure?
