What's your number? Find out here

      Want to know approximately how many people were on earth when you were born? With this BBC website, you can by simply entering your date of birth. 

     I was quite surprised that there were less than 4 billion people on the planet when I was born and we have expanded to 7 billion in less than 40 years. Our children are growing up in a world where such changes will force them to deal with unprecedented challenges.
