BBC has created a really interesting interactive feature called 'The world at seven billion' giving you a number based on age as to what person on Earth you are.

Alongside this, you can see the ratio of births to deaths for the country you live in (along with the average number of immigrants per month), giving a percentage of growth rate (for UK its +0.6%).  Also the estimated life expectancy of your gender based on your country, and a general page of facts to conclude the experience with an insight into the future of population growth plus a novel little fact (for UK it's that people have, on average, more than one mobile phone subscription per person).  It's a really interesting read and ultimately puts forward the statistics of possible over-population scares.  Something you have to do by visiting the BBC site here.
