” FUKUSHIMA–Fukushima Prefecture’s population has declined by 5.7 percent since 2010, its largest recorded drop and the cause of a widening gender gap in some areas, according to national census figures announced on Dec. 25.
The population drop is mainly due to ongoing evacuations following the Fukushima nuclear disaster, according to the preliminary figures released by the prefectural government.
The prefecture lost 39,715 men and 75,743 women, a decrease of 4 percent and 7.3 percent from 2010, respectively. The difference is thought to have been caused partly by the majority male presence in reconstruction efforts.
A prefectural government official said the diminishing population is “attributable to a considerable number of people who have evacuated to places outside Fukushima Prefecture.”
On the gap between the male and female populations in some municipalities, the official said, “I assume that most of the workers who relocate themselves to these municipalities for the purpose of carrying out work related to nuclear power plants and reconstruction efforts are male, but many of the evacuees are female.”
The national census figures are the first released by the prefectural government since the 2011 Great East Japan Earthquake and tsunami, which triggered the nuclear disaster at the Fukushima No. 1 nuclear power plant.
Fukushima prefecture’s population as of Oct. 1 stood at 1,913,606, down 115,458, or 5.7 percent, from the last census in 2010.
Among the six towns and villages where the entire population has left under evacuation orders, four towns recorded zero inhabitants: Okuma and Futaba, which co-host the nuclear plant, and nearby Tomioka and Namie.
The village of Katsurao had 18 people who have returned to their homes after being evacuated. They are recorded as temporary residents, but the central government is working to make their resettlement permanent. Katsurao’s evacuation order is scheduled to be lifted next spring.
Naraha, where an evacuation order was lifted on Sept. 5, also experienced a massive decrease in its population, with 976 people living in the area, down 6,724 people, or 87.3 percent, from 2010. The figures illustrate the fact that few evacuees have opted to return home.
The town of Hirono, where a large portion of the population is involved in nuclear reactor decommissioning work, tallied a male population of 2,746, up 2.3 percent from 2010. The female population, on the other hand, was about half that figure at 1,577, down 42.3 percent.
The population figures are based on the number of people living in the prefecture as of Oct. 1, irrespective of whether they are registered as local citizens.
In areas where entry is restricted due to high levels of radiation from the nuclear accident, municipal employees and police officers were deployed to survey the population for the census. ”
