8% of a population doing any singular thing is rather significant.
For instance: in the 90's less than 10% (but more than 5%) of British people were going to university. But that has profound effects on the population.
There’s been roughly 1 copy of the Bible printed per person alive on the earth. Not all of them are still around, but it’s likely there is still at least 1 copy per 2 people.
According to Statista, 85% of Swedes self-identify as either "non-practicing Christians" or "religiously unaffiliated", unlikely they have a bible at home if that's accurate. "Church-attending Christians" come up as 8%, and are likely to have a bible at home. "almost as popular as the Bible" seems, if Statista is right, very likely.
