As you've just heard, we love to set out on statistical quests set for us by you, our listeners.
Don't forget our website too, bbc.co.uk slash more or less, where you'll find some of our best stories.
More or less will be back next week.
Until then, goodbye.
Hello and welcome to More or Less on the BBC World Service, investigating the numbers in the news and in life.
I'm Jan Wong.
This week... How can a woman not know she's pregnant?
Just how uncommon is it for a woman to give birth without knowing she was pregnant?
But first, and still in a roundabout way on the subject of babies, the United Nations Population Fund, UNFPA, recently published a report describing the world's ageing population.
That's Dr. Ann Porlichko from the UNFPA.
She says we can be pretty confident about the numbers.
Fair enough.
But in the longer term, the figures aren't going to be dominated by the likes of you and me.
It's the birth of new people that will have the largest effect on future statistics.
And here's where it gets interesting.
For a long time, statisticians have observed something which they call the demographic transition.
So as countries get richer, their fertility rates drop.
And it's long been assumed that that's the way it will continue to go.
But what if it doesn't?
Professor Jane Falkingham is director of the ESRC Centre for Population Change at Southampton University in the UK.
