Looking at my counter scripts I noticed that the world population script wasn’t posted on this website. Now it is! You can find it in the left menu in the “Plugins/Scripts” section (‘Counters‘). It’s extremely easy to install and it will give you a HS device that contains the current world population and the growth since 1 day.

It’s unbelievable how many people get born every day and how steady that number is, around:

206,000 / day

Look at the Counter Project page for more information.
