the pattern that you've observed is largely for a very few rich countries.
Could it be that that's just due to immigration into those countries?
So the indigenous population in these few countries is also increasing its fertility rate?
If you're an evolutionary biologist, and as it happens I am, you might not be surprised by all this.
The idea that the wealthier we are, the fewer kids we have is, when you think about it, very odd indeed.
Normally, natural selection produces individuals who are very good at converting their resources into lots of fertile descendants.
It's a demographic paradox that in the past few centuries, developing societies haven't been filled by families who raise as many kids as they can possibly afford.
Almost the opposite, in fact.
Not much, according to Dr Paul Litschko at the UN.
We don't expect it to be that significant.
Maybe she's right.
Of course, one day we'll know whether our population projections beyond 2050 were accurate, whether the so-called demographic transition disappeared, or whether huge leaps in life expectancy changed the picture completely.
But forecasting population will always be a highly uncertain science.
Professor Jane Falkingham.
Now from future babies to unexpected ones.
A recent news report told the story of a Fijian soldier serving with the British Army in Afghanistan who gave birth having not realised she was pregnant.
