The average Japanese woman is 50 years old

"In 2020, the median age of Japanese women will be 50."
I was shocked when I heard this before.
The median age of 50 years old means that half of Japanese women are over 50 years old, so it would be safe to say that the average Japanese woman is 50 years old.

Since it was quite some time ago that I heard this, I looked up the data now, past the year 2020.
However, although data on average age by gender was available, I could not find data on median age by gender.

So I calculated it from the following data published by the Statistics Bureau.

統計局ホームページ/人口推計/人口推計（2021年（令和3年）10月1日現在）‐全国：年齢（各歳）、男女別人口 ・ 都道府県：年齢（5歳階級）、男女別人口‐

Using this data, the median age of the male and female population was calculated as follows
Male 47 years old
Female 50 years old

As previously predicted, the median age for women was 50 years old.
The result for men remained almost unchanged at 47 years old.
This result reflects Japan's aging society with a declining birthrate, and I feel that the retirement age will continue to increase.
