Research and Statistics Department
The Research and Statistics Department (RSD) of the Bank of Japan has revised the Consumption Activity Index (CAI) as follows. Due to the revision, figures for the CAI have been retroactively revised.
Change of the source statistics for "communications"
In the CAI, "communications" in the Indices of Tertiary Industry Activity has been the source statistics for the real index of "communications." The RSD has changed to a new compilation method under which it deflates sales for "communications" in the Monthly Survey on Service Industries by the corresponding price index in the Consumer Price Index (CPI). Reflecting this change, the CAI has been retroactively revised.
