Need some numbers for cocktail party chit chat?
Statistic junkies will twirl in delight to visit the Worldometeres web site.
You’ll find all kinds of world statistics updated in real time. You can change your computer clock to check out future stats.
For example, if you are curious to learn the number of HIV-infected in 2050, change your system time to 2050. Worldometeres will calculate values based on current interesting statistics and demographics data.
Of course the site comes with the disclaimer: “Do not use for exact calculations.” I should hope not!
