Re: Is this interesting enough?

Where Japan goes, so go all of us, just on slightly different time scales.
Our world is ageing fast. Take this 150 year animation 1950-2100 (obviously half historical data, half projection).
In 1950 only a handful countries had a median age above 30. To list: Austria (35.7), Germany (35.2), Scandinavia (31.7-32.4), Australia (30.4), and the USA (30.2). Japan had a median age of 22.3 years.
Now in 2020 it is fairly even mixed, the world median age crossed 30 years last year. Japan has a median age of 48.2.
In 2100 only Niger in the Sahel is projected to have a median age below 30 (29.4). Japan would have a median age of 51.8.
(They would join Spain (51.7), South Korea (51.6), Poland (51.5), Iran (51.2), Nepal and Costa Rica (51.1), Brazil (50.8 ), Bangladesh (50.6), Italy and Thailand (50.5), Mexico (50.4), Turkey (50.2) and Chile (50.1) in having a median age over 50. )
Our World in Data: median age 1950-2100
More recent studies indicate we will age somewhat faster than the UN projections. Here's an animated GIF of the UN data.
