I just came across this on the BBC Two website and had to share with you all: 
We've once again teamed up with the Oxford University Press 
to analyse the 40 MILLION words children used in this year's 500 WORDS 
competition.
The analysis of 90,000 stories has revealed a wealth of fascinating 
insights into the lives of British children and the remarkable ways they
 use English. You can see some headline findings on this page- 
  
 

Our Word Cloud shows some of the most used words - 
Mum is THE word of 500 WORDS 2013, with over 115,000 occurrences and regional variations, including mom and mam.
 

Poor 
dad
 only just scrapes into the Top 15, although he does star as an action 
man in several of the Top 50 stories - fighting aliens, exploding, and 
building a time machine!
 

Children are fanatical about fairy tales and mad for magic, with 
dragons, 
monsters, 
giants, 
fairies and 
wizards dominating.
 

Only man's best friend can rival dragons and monsters in the numbers stakes with 
dog appearing over 25,000 times.
  
James Bond is by far the most popular fictional character. He is name-checked nearly 1,000 times, while 
spy is even more popular.
One Direction are the most popular music act (and yes, Harry Styles is the most popular band member).
 
Top Gear is the favourite TV show, followed by 
Tracy Beaker, 
Doctor Who, 
EastEnders and 
Britain's Got Talent.
Chris Evans retains his crown as most popular individual celebrity.
 

The majority of references to the 
London Olympics came from stories penned well away from London, in places such as Wales, the Scottish Highlands & Islands and Devon.
 
Usain Bolt sprints ahead in the poll of most popular sports person, tying for Gold with last year's winner 
Wayne Rooney.

The word 
car appears over 26,000 times, with a substantial number featured in the girls' stories.
 

The most popular new word this year is 
gangnam (while 
Psy himself makes his 500 WORDS' celebrity chart debut at number 22).
