Full time students have never been counted as part of the workforce. Stay home mothers either. To me the most important stat are males between 22 and 60. All(most) of them should be working.
It has been curious to me that those full time students who work 20 or 30 hours a week are not counted as part of the
labor force. I believe a full time student is defined as one who is taking 9 or more credits (3 credits per course or 3 courses). It is not impossible to take three courses and work full time.
