"Belated" Christmas gift? From the data, the most concentrated month of birth in Chinese people

What does this topic have to do with me?

Have you noticed that several relatives and friends were born in September? Data shows that September each year is the peak period for babies born globally. Behind this phenomenon, it may be closely related to the annual Christmas, and there is the mystery of the laws of nature.

Christmas is not only gifts and food, but also a season of love and peace. This warmth of love seems to have the best witness in nine months.

About nine months after Christmas every year, many countries around the world will usher in a baby boom, and our country is no exception. Next, let us use the data to solve the reasons behind this seasonal fertility peak.

According to data analysis by the National Registration Bureau, September and October each year are the months with the most babies born in my country, and the number of births per day starts from at least 60,000. In addition, more babies were born in the first 12 days of November, just before Valentine's Day in February.

Of the ten most common birth dates in my country, five fall in September; among them, more than 64,000 babies were born on September 9, 15, and from September 18 to 20, which means that a large number of conceptions may occur around Christmas every year.

In addition, the dates of birthdays with overlapping even numbers, such as: January 1 and November 11, etc., are much more common than other days.

Why are there many babies in September?

According to an article in "Reader's Digest", the cold weather at the end of the year makes people more inclined to stay indoors and increase the chances of intimate relationships between partners. Therefore, conception from November to December corresponds to the peak of birth from the end of August to September.

The article quotes medical management book writer Todd Furniss, pointing out that humans may have seasonal fertility patterns and the winter conception rate is high. From an evolutionary perspective, babies were born in late summer and early autumn, and it was a season of adequate food and mild weather.

In addition, most office workers will take leave at the end of the year, which will reduce work pressure and increase time to spend time, which will increase the chance of conception.

Nevertheless, it must be emphasized that not all pregnancy lasts a full nine months, and not all pregnancy or delivery are planned, so we cannot know for sure why these common birthday months or dates occur.

However, the existence of this law allows us to see the subtle and interesting connections in human life: the gathering of festivals and the change of seasons are quietly affecting the arrival of new life.
