Fukushima population over 15 y.o shrinks fastest all around in Japan

According to the Labor Force Survey [Link] of Ministry of Public Management, Home Affairs, Posts and Telecommunications, Fukushima population of over 15 years old decreased by 30,000 from the first quarter of 2011 to the one of 2012. This is the largest decreasing range among 3 prefectures in the disaster area.

The graph below shows the decreasing percentage compared with the corresponding quarter of a year earlier.

3 prefectures in the disaster area, Iwate, Miyagi, Fukushima, also Tokyo and Okinawa are compared in the same graph.

Okinawa is the remote island far south to the main island.

Tokyo and Okinawa are almost stable. All of the 3 prefectures are in decreasing trend but the decreasing percentage of Fukushima is recognizable.

Fukushima population shrinks faster than all the other prefectures



The graph below shows the percentage of decrease / increase of the population over 15 years old from the first quarter of 2011 to the one of 2012.

All the prefectures are compared in the same graph, the biggest decrease is Fukushima. The second biggest decrease is Iwate.

The biggest increase is Okinawa.

  1. The decline of population in this article is not clear to me. How are they keeping track of it? Does it include the number of people who moved out of the prefecture? It is probably true that some people have deceased after the disaster but also it’s true that some people moved to other prefectures.

  2. FUKUSHIMA DIARY FR – La population des plus de 15 ans s’effondre dans tout le Japon.
    Par Mochizuki, le 15 août 2012.

    Selon l’enquête du Labor Force du Ministère de la Gestion Publique [http://www.e-stat.go.jp/SG1/estat/GL08020103.do?_toGL08020103_&tclassID=000001007576&cycleCode=0&requestSender=dsearch], des Affaires Familiales, des Postes et Télécommunications, la population des plus de 15 ans de de Fukushima a chuté d’environ 30 000 entre le premier trimestre de 2011 et celui de 2012. C’est la plus grande diminution des 3 préfectures de la région de la catastrophe.

    Le graphique ci-dessous montre la diminution des pourcentages comparés avec le trimestre correspondant de l’année précédente.

    Les 3 préfectures de la région dévastée, Iwate, Miyagi, Fukushima, ainsi que Tokyo et Okinawa sont comparées sur le même graphe.

    Okinawa est l’île éloignée au large de l’île principale.

    Tokyo et Okinawa sont à peu près stables. Les 3 autres préfectures sont sur une pente descendante et la chute du pourcentage de Fukushima est patente.

    (graphique par préfecture)

    Le graphique ci-dessous montre le pourcentage d’augmentation/réduction de la population des plus de 15 ans entre le premier trimestre 2011 et celui de 2012.

    Toutes les préfectures sont sur le même graphique, la réduction la plus importante est à Fukushima. La suivante est Iwate.

    La plus forte augmentation est dans la lointaine Okinawa.


  3. People moved to Okinawa because it presumably has less radiation. Not too complicated.

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
