Outside a train station near Tokyo, hundreds of people cheer as Sohei Kamiya, head of the surging nationalist party Sanseito, criticizes Japan’s rapidly growing foreign population.
As opponents, separated by uniformed police and bodyguards, accuse him of racism, Kamiya shouts back, saying he is only talking common sense.
Sanseito, while still a minor party, made big gains in July’s parliamentary election, and Kamiya’s “Japanese First” platform of anti-globalism, anti-immigration and anti-liberalism is gaining broader traction ahead of a ruling party vote Saturday that will choose the likely next prime minister.
The crisis isn’t simply from a declining total population number. It’s from the demographic shape of that population. Here’s Japan’s population pyramid. As you can see, it’s not really a pyramid - it’s heavily weighted at the older end. As people continue to age that big bulge reaches retirement, and then you have more people retired than you have people still of working age. This causes a number of problems.
Yes, I’m asking you (or other people making the argument that population decline is so bad) to list them.
When an overwhelming proportion of the population is elderly, an overwhelming proportion of the working age populations earnings have to will go to support them. This is measured by an economic ratio known as the dependency ratio which is going to get out of hand for countries like Japan. The strain on public finances paying for pensions and healthcare reduces quality of life for everyone in the country and depresses economic growth as young people working to support the countries elderly population and their own parents have less to invest in the wider economy.
You’re still missing the basic point by talking about the “population decline.” The crisis is not the decline. The crisis is the age distribution.
Here’s a page discussing some of the specific problems of an inverted population pyramid, and it uses Japan as a specific example of a population facing this.
