What number are you? Answered
With almost seven billion people alive on the planet, the BBC have produced a fascinating little widget for working out what number person you are. All you have to do is input your date of birth.
As you can see from the chart below, I was the three and a half billionth person on the planet when I was born.
The set-up will also tell you how fast your home country's population is growing.
What's scarier, though, is the data you get for today (27th October, 2011): as I type, almost 8.5% of all the humans to have ever lived are alive right now. To put that in perspective, if the human population was stable, and not rising, then all 83 billion of humanity's historical population would have been born in the last 1200 years.
