Japanese demographic statistics largely differ from census result

The population statistics of Ministry of Internal Affairs and Communications show Japanese census result is largely different from demographic and migration data.

It is the statistics titled “Time series of population estimates”.

From 2005 to 2010, Japanese population increased by 176,826 based on the population census.

On the other hand, natural change (Live birth – deaths) is summed up to -232,995 in the same period based on the vital statistics by the Ministry of Health, Labour and Welfare.

Also net migration and net increase by change of nationality was -243,538 according to the Ministry of justice.

In total, -476,533 people supposedly decreased from 2005 to 2010.

As a result, 176,826 Japanese increased when it theoretically should decrease by -476,533 for some reason.

The following demographic statistics show -1,176,356 Japanese “increased” from 2011 to 2015, which doesn’t seem to have a significant turning point in deaths since 2011.

Older files than 12. 2011 cannot be accessed by Mac used by Fukushima Diary so it cannot be checked if the past demographic statistics were not modified at some point after 2011.

Les statistiques démographiques japonaises diffèrent largement des résultats du recensement


Les statistiques sur la population du Ministère des Affaires Internes et de la Communication montrent que les résultats du recensement japonais sont largement différents des données sur les migrations et celles démographiques.

Il s’agit des statistiques intitulées “Time series of population estimates” (Séries chronologiques sur les estimations de la population).

Entre 2005 et 2010, selon les recensements, la population japonaise a augmenté de 176 826.
Par ailleurs, selon les “statistiques des vivants” du ministère de la Santé, du Travail et des Affaires Sociales, l’évolution naturelle (naissances – décès) se résumerait à -232 995 sur la même période.
En outre, selon le ministère de la Justice, le bilan net des migrations et augmentation nette par changement de nationalité est de -243 538.
Au final, entre 2005 et 2010 il y aurait eu une diminution de -476 533 personnes.

Donc, la population japonaise aurait augmenté de 176 826 alors qu’elle est aussi supposée avoir diminué de 476 533 personnes.

Les statistiques démographiques qui suivent présentent une “augmentation” de -1 176 356 entre 2011 et 2015, ce qui ne semble pas marquer de changement particulier sur les décès depuis 2011.

Les fichiers antérieurs à décembre 2011 ne peuvent pas être lus par le Mac du Fukushima Diary, qui ne peut donc pas contrôler si les statistiques démographiques antérieures ont été modifiée à un certain moment après 2011.


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.
