population shift -1088------3125---- -4087------ -30615

Comparing the population shifts between the pervious year and this year, a decrease in birth rate and an increase of death number are observed all over Japan. 
Especially, mortality increased overall.  
Birth rate began to decline from November last year, and we need to focus on the future trends.
The number of out-migrant from Fukushima decreased compared to the time of the accident, however, it shows a continued increase. 
We consider it's because the government or the prefecture haven't taken measurements to provide a security to the residents. 
The following figures shows the population shift in Ukraine and the process of malignant tumor morbidity in Belarus.
