33 分钟In rich countries around the world, we are having fewer and fewer children.
In the US, fertility rates are now below the replacement rate of 2.1,
or what it would take to sustain a constant population.
This is a slow but massively important trend, socially, culturally and economically.
An ageing and shrinking population has consequences for the workforce, the public finances and the environment.
This week we are going to ask, how do falling fertility rates and ageing affect the economy?
And what can we do about it?
This is The Economics Show with Samaya Keynes.
I'm joined this week by Melissa Carney, director of the Aspen Economic Strategy Group,
which recently put out a series, Demographic Headwinds,
the Economic Consequences of Lower Birth Rates and Longer Lives in the US.
She's joining me from Chevy Chase, Maryland.
Melissa, hello.
Hi, thanks for having me.
It is great to have you with me.
Okay, on a scale of one to 10.
How big of an economic challenge is the current trend in U.S. Fertility?
Oh, that's a hard one.
I do n't want to sound like an alarmist and put this close to 10,
but I definitely am going to put it above the median of five.
