2012 List: Mathematical Prediction

Last year in September, I did a mathematical prediction for the list published this May, and now I'm doing one for the one released next year.
If you didn't read my post last year, basically what I did was look at the number of babies born with a certain boy name, see how much it increased and decreased from the previous year, and apply those changes to the new ranking. Like I said last year, we never know if a name will continue to rise or start to fall, since things change year to year, but it's all in good fun.

So let's look at the future ranking of 2012, if names performed exactly the way they did in 2011:

01 MASON (+1)
02 JACOB (-1)
03 WILLIAM (=)
04 NOAH (+1)
05 JAYDEN (-1)

England & Wales Ranking (2011)

So the combined ranking for England and Wales is out, and there are new number ones for boys and girls. Harry takes over from Oliver, and Amelia is the new ranking leader for girls.

However, the popularity lists for England and Wales separately show how different naming tastes can be for each region.

Wales

1. Oliver / Lily
2. Jack / Amelia
3. Jacob / Ava
4. Riley / Ruby
5. Ethan / Olivia
6. Alfie / Seren
7. Harry / Emily
8. Dylan / Ella
9. Thomas / Mia
10. Charlie / Megan

England

2011 List: Mathematical Prediction

This Summer, I had some extra time to spare, and I thought about comparing the popularity change of the boy names between 2009 and 2010, based on the number of babies born, and use those numbers to predict the 2011 ranking. I did round up the numbers to make things easier for me, otherwise it would've taken me way too many hours.
So this is how the 2011 list would look, if the names this year had the same change (whether positive or negative) as last year:

01 Jacob (=)
02 Mason (+10)
03 Jayden (+1)
04 Ethan (-2)
05 William (=)
