|1/Effective 6 March 2018, the Philippine
Statistics Authority (PSA), rebased the Consumer Price Index (CPI) from 2006
to 2012. Methodological changes were also introduced in the 2012-based CPI.
In the new series, the chain method is used as it will provide timely
indicators since this method allows the inclusion of new commodities in the
market basket that are frequently purchased because of the changing consumer
taste and preferences and technological changes. The new (chain) method also
allows the exclusion of commodities as a result of obsolescence.
