What’s Your Number?

Extra

As the world’s population is expected to reach nine billion by 2045, based on figures from the UN Population Division, UK broadcaster the BBC has created a micro-site for people to make sense of the figure and learn more about how exponential population growth is expected to change their lives.

What’s Your Number encourages users to enter their birth date and location to see where they fit into the human population, educating them about how the planet's resources will not support the current rate of growth if we do not become more sustainable. The UN estimates that by the 2030s we will need the equivalent of two Earths to support us if our current population and consumption trends continue.
