Are there a lot of writers publishing Swedish only? I'm learning Swedish very slowly, and would love to know how the Nordic languages are fairing amidst English's cultural domination.
It depends on what you would consider a lot. The swedish writers organisation has about 3000 members [1] and 1720 Swedish books of fiction was published 2016 [2].
