Statistics

Duotrope is the largest site listing writing markets currently. They report that about 8.5% of story submissions result in an acceptance.

My own figures, at the end of 2009, are currently:

Acceptances: 3
Rejections: 21
Acceptance Rate: 12.5%

In other words, I'm doing better than average...just! I'm hoping for 2-3 more acceptances in January to try and get that figure up nearer 15-16% which would be a very healthy average.
