These are stats for Poland for 2009 - only paper books:
38% of Polish citizens bought or read at least one book (58% in 2008)
40% of the 38% group were using public libraries
Most popular genres: love stories (18%), suspense & thrillers (15%), business, self-help, school books & encyclopedias (14%)
Electronic publications almost didn't exist out here back in 2009 - except for pirate copies of course. So there was no ofiicial statistics for those yet. They are starting to be more popular, but in my opinion it will take a lot of time to make them more popular.
TOday, the biggest publishers are not interested in investing money into ebooks since there is not enough reading devices in affordable prices available yet. Hardware vendors are not interested in getting the pricing for ereaders down yet since there is not enough ebooks available there thus not many customers for readers. So each side waits for the other...
Then the pricing - publishers here say that there is no reason for them to set a price of an ebook to lower level than dead tree edition since they state it is the same cost of investment for them (I do not agree with that entirely) - so the ebooks that come out now are at the similar price as paper back edition (plus DRM) so they are still not that popular (since the market is still emerging , you need to consider purchase of a reader for significant amount of money still, then buying an ebook for almost the same prices as paper edition - convincing? nah, i don't think so).
I do hope the situation will change sooner than later - more affordable ereaders, DRM free publications, cheaper ebooks with bigger and bigger selection of the titles...
