The total number of children that each Japanese woman will have in her lifetime (total fertility rate) was 1.29 in 2004, but it has been declining since 1982. However, it has improved a bit in recent years, and in 2012 it was 1.41. This is in the top 10 of the world’s lowest countries, after Belarus and South Korea. It is said that a birth rate of 2.07 is necessary to maintain the current population of Japan. This percentage is what is needed to maintain the current population of Japan.
The number of children among the population, once over 30%, has also dropped to 12.9%.
The explanation for the declining birthrate trend is usually said to be that more women are active outside of the home, and more women are marrying later and becoming single. The income gap seems to be narrowing. There are more and more jobs available for women, and more companies are giving them the same opportunities for employment as men. Women today enjoy a degree of independence that has never been known before.
As a result, there is a movement to delay marriage or stay single.
It seems that women are choosing to have fewer children after marriage because they have more job opportunities, more money and time to raise children and educate them, and poor housing conditions.
