Explaining Olympic medals, a follow-up

Two weeks ago, I posted some stats on the nations that were winning the most Olympic medals in the first week of the games. I thought I'd follow up with some additional charts now that the games have concluded. These are for the top 21 medal-earning nations, rather than every country, so please forgive the incomplete dataset.

I should also mention a little regression analysis I did showing that overwhelmingly the best predictor of how many medals a country won was how many athletes they sent to the games. The more you play, the more you win. Not shocking, I know, but still a better predictor than wealth. However, GDP turns out to be the best predictor of how many athletes a nation will send. So national wealth is important, but somewhat indirectly.

Anyway, charts are below the jump. North Korea, while having a great first week, fell quite a bit in most rankings. The big story now is Jamaica, a small and relatively poor country that won a ton of medals.
