Just been on this BBC page (apologies to those who can't access it) and entered my date of birth, country and gender and got this:
You are 58, female and living in the United Kingdom
(So the world's population has grown by over 4 billion in my lifetime! I only had one, honest!)
You were the 75,976,087,095th person to be born on Earth.
Your country's population is 62,035,570
What's next? The global population will continue to increase during your lifetime and beyond, reaching 10 billion by 2083. However, the rate of growth is expected to slow. Little of the current growth is happening in developed countries like yours.
Longer lives: In your area, women can expect to have one or two children. People are also living longer. This means people of working age like you will be supporting increasing numbers of older people. By 2050, there will be just 2.2 working-age people supporting every person 65 or older. In Europe, this will drop to two.
Battle for resources: It is estimated that your group of the richest countries consumes double the resources used by the rest of the world. The UN estimates that if current population and consumption trends continue, by the 2030s we will need the equivalent of two Earths to support us.
Did you know? By mid-century, the world's urban population is likely to be the same size as the global population was in 2004.
The population of the United Kingdom has grown by
