[Star Wars] Why was the Force unbalanced? And did Anakin Skywalker bring balance to it?

If the Jedi believed the Sith were extinct why did they believe the Force was unbalanced? What balance did they think Anakin would bring? And if he did bring balance how did he do it?

Balancing the Force means removing the taint of the Dark Side from the galaxy, since evil represents a perversion of the intent of the Force.

The Force is the embodiment of life, and the connectivity between all things. The Dark Side is an inversion: selfishness, the accumulation of power with no regard for others.

Anakin balanced the Force by eliminating both himself and the Emperor. An additional argument can be made that he removed the unhealthy corruption of the Late Republic Jedi Order, which had become self-serving and unfocused.

(Breaking the 4th wall: So many people disagree with this answer, but it's straight from George Lucas. It's perfectly possible that the new trilogy will alter this interpretation of the Force, but until then this is about as correct as you could be.)
