Bumping the thread.

Don't bump after 4 minutes. If no one has answered before it drops off the first page, THEN a bump is permitted.

As for your original question, this most basic of information is right there on your main nation page. I don't care how new you are, that's painfully obvious.

Population is on your nation summary. You can see your GDP in the economy tab (the factory button), though it doesn't mean anything since currencies are all different.
