Due to the problem that the Ministry of Land, Infrastructure, Transport and Tourism ordered the rewriting of the survey form of statistics showing the trend of orders in the construction industry and doubled the data, the original of the previous survey form was discarded after the retention period of 2 years. It turned out that it was done.
It seems that the handling of inappropriate data has continued for eight years, but the issue is how far we can clarify the details and the actual situation of double counting in future investigations.
On the 15th, the Ministry of Land, Infrastructure, Transport and Tourism revealed that there was improper handling of data in the "Construction Work Order Dynamics Statistics" that shows the monthly order trends of the construction industry.
Data is collected monthly from businesses in the form of "survey forms", but the Ministry of Land, Infrastructure, Transport and Tourism submits survey forms for multiple months to the person in charge of prefectures at once after the deadline. Was instructed to rewrite the survey form by adding it to the order amount for the most recent month.
However, since 2013, eight years ago, even for businesses that were late for the deadline, the order record was not set to zero and the estimated order amount was entered, so the estimated value and the actual order amount were double-counted. Was there.
The Ministry of Land, Infrastructure, Transport and Tourism has a policy of investigating the circumstances retroactively, saying that "there is no choice but to review what happened this time from the past", but the original of the previous questionnaire has passed the retention period of two years. Therefore, it has already been discarded.
This statistic is also used in the calculation of GDP = gross domestic product, but the issue is how far we can clarify the details of rewriting and the actual situation of double counting in future surveys.
