Consumer price index is indicates the change in average prices for commonly purchased household goods and services in the Philippines on the basis of the current base period of 2012.
The CPI being released monthly by NSO is the "all-income" CPI at the national level, Metro Manila and areas outside Metro Manila. All-income refers to the average Filipino income-earning households and includes those belonging to the high- middle- and low-income brackets. This means that expenditures of all income-earning households are reflected in the current CPI weights. The index measures the changes in prices affecting households from all income groups, not only the "DE crowd", which would be those belonging to the bottom deciles in the income distribution.
The CPI is computed using the weighted arithmetic mean of price relatives, a variant of Laspeyres formula with fixed base year period weights.
Some data are seasonally adjusted and revisions are updated when next period data is out.
