In 2013, I had calculated the expected rate of unmarried people.
Well, at the time, I didn't take it too seriously and put out these desk simulations as a warning bell that this was a possibility.
To be honest, I was surprised to learn recently that 47% of the population will be unmarried by 2040.
By the way, if you apply my formula for predicting the unmarried rate (0.6417x - 1270.7 for males, 0.6417x -1280.0 for females x: Western calendar), the rate is roughly "34%".
However, in the view of the following table, it seems to be generally consistent.

Back in 2013, as I stared at the data, I had an ominous feeling that "this might not be linear (equation).
This is because there are signs of an exponential increase, especially in the lifelong singleness rate for women.
However, if this is taken into account, the lifetime unmarried rate for men would jump to a ridiculous value, as the female unmarried rate would be greatly affected. At the time of writing that column, I decided I waited and saw.
As it turned out, there was no need to be cautious.

I've been saying for quite some time that we need to think about a social system where non-marriage is the default, but no one (not even the company) has taken me seriously.
In any case, a society with a declining birthrate in Japan is certain.
There is an urgent need to build a social system that does not assume human resources.

And if we continue to talk about "childbirth based on the system of marriage" and other nonsense others,
"Zero emissions" will easily be achieved by the population before oxygen dioxide.
