The government said Friday it will conduct a sweeping review of key statistics after the labor ministry was revealed to have published faulty jobs data for more than a decade.
“It’s very regrettable that we have a situation that impairs the credibility of our statistics,” Chief Cabinet Secretary Yoshihide Suga told a news briefing.
The government lists 56 reports as key statistics, ranging from gross domestic product and the population census to data on dairy products.
Suga also said the government will rework the state budget for fiscal 2019 to include the cost of reimbursing people who did not receive enough benefits due to the faulty jobs data.
The Ministry of Health, Labor and Welfare admitted Friday that it had failed to pay more than ¥53 billion in unemployment insurance, workers’ compensation and sailors’ insurance to nearly 20 million people beginning in 2004.
The issue came to light after it was revealed that the ministry had published its monthly labor survey without collecting enough data.
Under existing rules, the ministry must review all business establishments in the country with 500 or more employees. But in Tokyo it had collected data from only a third of the roughly 1,400 such establishments, leading the data to show nationwide wages that were lower than they actually were.
The ministry said staff members involved in compiling the survey results began the practice in 2004 and continued through 2017, when it was discovered internally. But the issue was not made public until the Ministry of Internal Affairs and Communications found an inconsistency in December.
The ministry continued to publish the survey using specialized software to make it appear as if it had collected the necessary data, sources familiar with the matter have said.
Labor minister Takumi Nemoto apologized Friday for the faulty data but said he doesn’t believe the ministry tried to systematically cover up the issue at this point of time.
He said the ministry would continue its investigation and may punish those found to be responsible.
The draft budget for the year starting April 1 was approved by the Cabinet of Prime Minister Shinzo Abe last month and was to be deliberated in the upcoming Diet session. Finance Minister Taro Aso told reporters the budget will likely need to be re-approved by the Cabinet.
The issue is likely to draw strong criticism from opposition lawmakers during the session, giving them ammunition ahead of local and national elections later this year.
Of the nearly 20 million people affected, some 19 million were unable to receive a total of ¥28 billion in unemployment insurance benefits.
Among those entitled to workers’ compensation, 270,000 people did not receive a combined ¥24 billion in disability pension benefits while 450,000 people lost out on a total of ¥150 million in lost wage benefits.
A further 10,000 people who work on ships were unable to receive a combined ¥1.6 billion in sailors’ insurance benefits, and there were an additional 300,000 cases of business owners not receiving their share of ¥3 billion in employment adjustment subsidies.
Toshimitsu Motegi, minister of economic and fiscal policy, said Friday that the Cabinet Office would need to correct figures on employee compensation, which it publishes along with GDP every three months.
