New Data: China - CPI - Index and SA
Friday, 02 Mar 2012 09:27 ET
By Megan Perkinson
February 2012 -- To supplement reported consumer price trends, Moody's Analytics has computed an index in NSA and SA versions (two new monthly series from 1986).

Motivation: Our national source for China reports consumer price trends as month-over-month and year-over-year growth rates, which are inconvenient for long-term analysis.

Response: For international consistency, we have computed an index with a single base year, and a seasonally adjusted version of sameĀ (series CPITTUM.ICHN and CPITTAM.ICHN, respectively).

Properties: Both series begin in January 1986 and have a base of 2005=100. Expect the NSA series to remain in sync with the reported values, and for the SA series to be revised with each new historical value appended to the NSA series.


  • Input: CP%TTUM.ICHN, Reported Y/Y percent change, starts January 1987.
  • Input: CP%TTMUM.ICHN, Reported M/M percent change, starts January 2005.
  1. Create index CPITTUM.ICHN using the M/M growth rates of CP%TTMUM.ICHN from January 2005 to December 2005. (We use only part of this series because the Y/Y has official primacy.)
  2. Grow the index forward and backward using the reported Y/Y percent change, CP%TTUM.ICHN.
  3. Rebase the index to 2005=100 by dividing the entire series by the average of its 12 values in 2005.
  4. Seasonally adjust using the U.S. Census Bureau's X-12 ARIMA program, producing CPITTAM.ICHN.
