I read 54 books total (over 17k pages), so that is the number too keep in mind when looking at percentages. I'm mostly interested in diversifying my reading in various ways, I want to read outside my genre norm for instance, and I want diverse authors, old and new books etc.
I'm starting with language:
Most of the books I read in 2015 were in English, only 5.6% were in my mother tongue, Norwegian. Shame on me. I hope that when I do this next year I'll find that raised to at least 10%, preferably more, but that at least is manageable.
Gender, is something I don't think about when I choose books, but that I find interesting to look at in hindsight. I read more women than men. The "Other" is just an umbrella for mixed gender books (anthologies, writing duos etc) trans and non-binary people, which means there are both men and women in that category as well (mostly those really). I'm have no desire to change this pie, it fluctuates a lot, though I'd love to read some more from those who aren't gendered.
Format is interesting, it shows that I read mostly digitally. Ebooks and Audiobooks make up more 60% of my reading. This is mostly because I've resolved not to do mindless book shopping. I'll buy something if I want to read it now, and if I really do want to read something immediately the internet is closer than my local bookstore (that for most of my reads don't have what I need anyway) or the library. I'm happy with these stats too, they're mostly just for logging my habits. Format doesn't matter to me.
All those dots represent the year the books I read were published, as you can see I read 10 books from 2015 and the same for 2014. Most of the books I've read have been published in the past 5 years (almost a quarter of the books), and only 4 were published prior to 2000. I want to change this a little. I have a lot of older books I want to read, so I'm aiming for 10 pre-2000 and then I'll read at will everything else.
Finally I'd like to talk about genre. I have no charts for this as most books that I read fit into more than one category, but I read speculative fiction the most, and within that again urban fantasy. I read about 50/50 young adult and stuff not labeled as such. I've also been reading quite a few memoirs. I think in 2016 I'll try to find a better way to sort this stuff so that I have a better idea of what exactly I'm reading.
