Largest mission sending nations

At the last mission-net congress in Germany, one of the speakers from S. Korea shared the following statistic with us about how many evangelical missionaries there are throughout the world and what countries they are sent from. No surprise to see USA and South Korea up there in first and second places respectively. I presume UK also includes Northern Ireland helping it to take third place.

Not sure about the source of the data but it can't be far wrong.

I'm looking forward to the next mission-net congress (December 2011 in Erfurt, Germany) and also to getting my hands on the new Operation World book which should be full of lots of statistics and concrete prayer requests concerning world evangelism.
