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.
