| 7.6 Deflator for Cost of Construction Work (Index) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
 |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Responsible agency: Construction
Research and Statistics Division, Information and Research Department, Policy
Bureau, Ministry of Land, Infrastructure and Transport. Purpose: To convert the current cost (nominal cost) of construction work into the real cost on the cost level at a base fiscal year. Cautionary note on use: The cost of construction work is mostly on a one-material one-cost basis. Therefore, in using deflators for the conversion into real cost, the preferred method is to reach the total by accumulating one over the other by using subdivided items. [Outline of System] Construction deflators are systematized as follows:  Base and weight reference period: F.Y. 2000.
Name and date of publication: The monthly publication "MONTHLY OF CONSTRUCTION STATISTICS", carries four-month old statistics. Language: Japanese. Part of the statistical tables are also in English.
