OK I have added a new sheet to show the by country figures. I've only done it for AF at the moment and I considered doing it for 2012, but then I realised that would be VERY SILLY, so I used 2011 instead. ;-)
LOL.
The result is more difference than I would have expected, so you were right to suggest that. The demand has gone up by ~1000 - so that is not great news. It also reveals some other interesting things - for example the likelihood of country 7% limit being hit. The numbers suggest that Egypt is the only country (in AF region) that could possibly hit the 7% limit - the other countries will not hit that limit before the global cutoff kicks in.
I actually expect AS to increase the most.
As I have mentioned before, I think in the case of Iran the return rate will have a significant increase for DV-2014 (sanctions, trembling economy, etc.) in addition to the increase in the selectees. But we would be just making up numbers if wanted to account for that.
