World population outlook 2007
It isn't entirely impossible that we're in that unlucky 50 million that haven't got a "match up".
But overall, male/female ration is not an excuse. True a lot of guys on /a/ have higher standards than they can live up to, but since woman power has taken hold in the last few decades, women are the same in just a general sense.
Also, modern societal conformity through extrovert mindsets (which, most girls fall into, despite their new found power) don't help the minority of males who have had the power to 'rebel' for-...ever, to get any partner who is open minded enough after the fact.
