arXiv only handles a small corner of scientific publications, so 0.83% doesn't sound out of whack. Most folks in biology or chemistry aren't on there, for example. A Nature study from 2014 (http://blogs.nature.com/news/2014/05/global-scientific-output-doubles-every-nine-years.html http://blogs.nature.com/news/2014/05/global-scientific-outpu...) pegs the number of papers published between 1980 and 2012, with at least one citation, at 38 million. So, 69 million publications including uncited ones and ones from outside this time range actually sounds like an underestimate - that is, the 69 million paper archive is probably missing a fair number of articles.
