"No children on the Children's Day after 1,000 years due to birthrate declining" - Child Population Web Clock showing birthrate declining in real-time-

A research group led by Professor Hiroshi Yoshida at Graduate School of Economics and Management, Tohoku University has developed and released Child Population Web Clock indicating the rate of child population decline in Japan in real-time, by using open source software. The Web clock has been produced in May 5, regarded as the Children's Day in Japan.



Child Population Web clock:



(1) As a result, the Prof. Yoshida's research team has estimated that there are 16,620,000 children in Japan as of May 5, 2012, decreasing about 300,000 children from last year and 1,550,000 children (equivalent to the population of Fukuoka City) from 10 years ago.


(2) Child Population Web Clock is showing that the child population is declining by one every 100 seconds. This clock gives us a strong impression that the birthrate in Japan is rapidly declining and effective solutions have to be adopted as soon as possible.


(3) Child Population Web Clock has also revealed that Japan would have only one child in May 3011, about 365,000 days from now. By the next year, therefore, there would be no children in Japan. It can be said that "The Children's Day would no longer come in May 5, 3012."
