The internet has not been a boon to truth, now we just have more data to confuse people with. And what's heart-breaking is how we all seem to have lost our ability to use our natural skepticism of crap and common sense in these situations.
Just because there is a number on a pretty slide does not make it true. Even if it is being presented by an authoritative person. Even if the slide has copious footnotes, with references to authoritative sources. (That last one is perhaps an even better reason to be doubtful!).
People: Be, a tiny bit skeptical (without being rude). And, never lose sight of your common sense!
