What happens to game saves when game uninstalled?

Hey Army,

I'm new to Android (and LOVE it), so I have some lame questions that I can't seem to find a good answer for on Google.

Using GTA: Vice City as an example:

-If I uninstall the game, does it auto-delete saved games?

Can I uninstall games, then still have my saved progress if I reinstall at a later date?
