New Data: Chile - CPI - SA
Wednesday, 14 Mar 2012 10:13 ET
By Megan Perkinson
March 2012 -- To supplement the reported consumer price index for Chile, Moody's Analytics has extended its history by 80 years, and created a seasonally adjusted version (one new monthly series from 1928).

Motivation: Our national source for Chile reports the headline consumer price index (CPI) with a base year of 2009 and in not seasonally adjusted (NSA) terms, beginning in January 2009.

Response: We have extended the history on the NSA fundamental series to March 1928 using the predecessor base-2008 index.  Additionally, for international consistency, we have created a seasonally adjusted (SA) counterpart.

Properties: Both series begin in March 1928. The index base is 2009=100. Expect the SA supplement to be revised with each new historical value appended to the fundamental.


  • Input: CPITTUM.ICHL, reported fundamental (2009=100), starts Jan. 2009.
  • Input: CPITT08UM.ICHL, predecessor (Dec. 2008=100), starts Mar. 1928.
  • Output: CPITTUM.ICHL, extended by 80 years to Mar. 1928.
  • Output: CPITTAM.ICHL, supplement (2009=100, SA), starts Mar. 1928.
  1. Extend the NSA series backwards to March 1928 using the growth rates of the previously reported base-2008 index series.
  2. Seasonally adjust using the U.S. Census Bureau's X-12 ARIMA program.
