How many people are there in the world?
We don’t know for sure as all figures are estimates, but UN data suggests there were about a billion people in 1800, 2 billion in 1927, 5 billion in 1987 and just over 7.5 billion today.
There are on average about 250 babies born every minute – more than 130 million in a year. It is projected that there will be 11 billion people by 2100. New UN figures are due out in June.
