a. Statistics concerning the overall picture of construction work
b. Statistics concerning trends in construction work
c. Statistics concerning the costs of construction work - Construction Deflator
d. Statistics concerning the actual conditions of construction business - Construction Work Survey (one of the surveys on construction work)
e. Statistics concerning depreciated or scrapped buildings - Survey on Building Destruction
The purpose is to show the construction business's standing in the Japanese economy and the size of construction activities. Such data enable us to assess the extent of the effect caused by the construction works on the Japanese economy. Statistics are compiled on the size and structure of construction activities in value terms and estimates for the fiscal year.
The Ministry of Construction (currently the Ministry of Land, Infrastructure and Transport) is responsible for the compilation of the statistics.
The Ministry of Construction (currently MLIT) has been conducting the survey since 1950 to explore the actual state of construction work that starts in each month nationwide, thereby producing basic materials to be used for the administration of construction and housing.
The Ministry of Construction (currently MLIT) has been carrying out the survey since 1955 for the purpose of grasping the contents of orders received from public and private organizations and monitoring the trend in orders for construction work. The survey is composed of Survey A and Survey B. The former covers construction companies with annual construction of completed amounting to 100 million yen or more, whereas the latter covers construction companies with a medium annual construction amount of completion. In both surveys, the companies are asked about their orders and contracts in value terms.
The Ministry of Construction (currently MLIT) has been conducting this survey since 1955 to illuminate the actual state of construction work and construction business. The survey covers the establishments of construction companies in the entire nation that are authorized and licensed under the Construction Business Law and the establishments that are directly controlled by public organizations. The topics of the survey include managerial organization, type of business, annual construction completed, orders and the number of workers.
The construction deflator is used for converting nominal construction cost (or business expenses) into real construction cost (or business expenses). The MLIT has compiled the "Construction Cost Deflator (since FY1960)" for general construction, the "Construction Deflator (since 1951)" for civil engineering work under the control of the MLIT, the "Land and Indemnity Deflator (since 1960)" and the "Business Expense Deflator (since 1960)." The base of each deflator is revised every five years.
The Construction Research Institute has been computing price index every month since 1980 to understand the fluctuation of building construction costs. The index concerning construction expenses (construction costs) includes the "Standard Index," "Structural Average Index," "Model Index" and "Regional Disparity Index." The base of this index is revised every five years.
The Japan Real Estate Institute computes the index since 1959 to illuminate the costs of wooden buildings in Japan and provide long-term time-series information on construction expenses in the index. The end of March 2000 is being used as the base.
MLIT has been conducting the survey. Its prototype is the "Survey of Building Damage," which was started in 1948. In 1951, the "Survey of Damaged Buildings" replaced this survey. At the same, time a new statistical survey, the "Survey of Scrapped Buildings," was added. As a result, these two surveys were combined into the "Survey of Building Destruction."
The "Social Capital of Japan - From flow to stock" (edited by Coordination Bureau, Economic Planning Agency) was issued in 1986. It was revised after ten years (in 1998) and titled "Social Capital of Japan - Stock towards the 21st Century (edited by Coordination Bureau, Economic Planning Agency)." This second edition was again revised into a titled "Social Capital of Japan - A stock transcending generations (by the Director General for Policy Planning, Cabinet Office)." In this edition, the stock of Japan's social capital is estimated in value terms, and flows of investment and natural disaster relief expenditure are estimated as well in value terms.
