Some figures and realtime displays on the world’s population: we are 7 Billion people!

November 2nd, 2011

By the end of October 2011, the earth’s population was estimated to reach 7 Billion people. There were some amazing data and figures communicated with this – artificial – border that had been passed:

• per second, there is an increase by 2.5 people, that is 150 per minute, 9.000 per hour and 216 every day – the error-rate is apparently up to 5 %
• there is quite a number of countries/areas where there exists no official statistics. So areas are being flown over with airplanes and estimates are made; or, from the number of cattle, the number of people in a certain area is inferred.

And I came across two pretty nice live counters/tools:
One is a live counter available at http://www.umrechnung.org/weltbevoelkerung-aktuelle-momentane/weltbevoelkerungs-zaehler.htm:

.

The other one is breathingearth.net:

and a truly impressive animation!
