Default Predicted global populations

I assume there are carefully-calculated predictions as to what will happen to worldwide population in the decades to come. Please could someone post figures for 2010, 2020, 2030, etc?

How much do these figures vary from source to source? Are they broadly consistent or do opinions vary wildly?

Thanks...

Funnily enough they said Australia was going to level off at 25 million people until they found out we were only having 1.3 kids per every couple. So we'll get there, just send us your rejects since convicts isn't a word used for todays criminals. We need to increase our workforce to support the baby boomers in retirement.

Can't they just emigrate?
