Normal completion of college education is at the age of 22 or 23, and this age is not the reason that hinders the increase of fertility rate. Even if it is shortened by two or three years, young people in this age group are even more reluctant to get married and have children too early because they are still children.
From my personal point of view, those who have never been to college generally get married earlier; Those who have gone to college are generally married over 30 years old. Those who have never been to college usually have three children; Those who have gone to college usually have one or two children.
There is a certain relationship between the improvement of fertility rate and the level of education. People with higher education will marry later and have fewer children. Compared with those who graduated from junior high school or high school, they got married earlier and had more children. At least that's the case here. I wonder if it's like this outside.
For example, this month, four or five people around me got married, all in their twenties and thirties. They all finished junior high school or high school, just went out to work for a year or two, and then got pregnant and got married.
Therefore, I can't deny the expert's advice. After all, it is still expert advice. I'll just listen. At least the situation around me is just the opposite of the expert's advice.
