I just have time for this quicky from goo Ranking tonight, a look at the distinctive features of an only child.
Over the 5th and 6th of October 2012 1,064 members of the goo Research monitor group completed a private internet-based questionnaire. 58.2% of the sample were female, 10.5% in their teens, 13.7% in their twenties, 26.6% in their thirties, 27.6% in their forties, 11.7% in their fifties, and 9.9% aged sixty or older. Note that the score in the results refers to the relative number of votes for each option, not a percentage of the total sample.
In university one of the guys I flat-shared with was an only child, and he probably matched just about every answer here!
