How many Death Eaters?

I don't know if this was mentioned before, but I wonder how many 
Death Eaters there are.

Before I read GoF, I thought that there were hundreds or thousands of 
Death Eaters  (in relation with about 6000 wizards and witches in 
Great Britain). But when the DE appeared after Voldemorts "rebirth" 
they made a circle around Voldemort. There were only a few DE, some 
are death or absent. Voldemort didn't say anything to some DE, but I 
don't think that there were so many DE unmentioned. And the circle 
cannot be so big for some hundred DEs.
And: Are they all the DEs of the entired world? Or only the DE of GB? 
IMO, they should be all DEs because Voldemort wanted to show all his 
followers that he is back.

What is your opinion about that?
