I was cleaning up some old files and I started looking at the contracts for the last five issues of Science Fiction Trails, which I used to edit. These are stats for accepted stories rounded to nearest 5 percent:
Texas 15 %
Foreign countries 15%
all others 15%
Percent of writers who had previously published in SFT or one of my anthologies 90%
Most popular states for buyers [direct sales from publisher]
all others 10%
What's it all mean?
Don't know, but sales and author origins do not have anything to do with where the population is.
