Seven Billion

by Jimmy L

According to the United Nations, the world population reached seven billion on Monday October 31, 2011. This figure is completely inconceivable to me, but the BBC website has created a website that makes it easier to see this number in the context of its numerous contributing factors. If you enter in your date of birth (since this is a British website, make sure you enter day first, then month and year), it will tell you what your number is,  i.e. how many people were alive at the time you were born. It will also tell you how many people have ever lived since history began (78.7 billion). If you click “Next”, it will break down population growth by country, gender, and other factors. If you’re interested in thinking about this topic more, check out some of these books:
