I subscribe to Analog Science Fiction/Science Fact and Asimov's Science Fiction and The Magazine of Fantasy and Science Fiction.

They publish annual circulation figures for print copies, but not for electronic copies.

Does anyone know whether such figures are publicly available?

I have figures for the print version, which are included (usually) in the January issue. They show a drop in print circulation of about 50% over the past ten years, from about 42,000 to 21,000 for Analog, 30,000 to 15,000 for Asimov's. I don't have recent figures for F&SF, but since they dropped to six 'double' issues a while back, I doubt that the news is good there either. (They were only 19,000 in 2005)

I'm hoping that electronic versions have been growing in circulation to make the numbers. Otherwise I fear these venerable magazines don't have long.
