The 2016-based CPI covers 368 representative goods or services. Item prices are collected monthly in 17 cities or counties. Approximately 33,000 prices quotes are obtained each month, and the quotes are obtained mostly by personal interview.
The weights are based on the 2016 Household Final Consumption Expenditure of National Income, which derives from the Family Income/Expenditure Survey. Weights will be updated annually from 2018.
Core CPI is defined as general CPI excluding prices of fresh fruits, vegetables, and energy (gas, electricity, fuels, lubricants).
To reduce discrepancies between the public's perception of price movements and the formal CPI, DGBAS produces analytic indexes:
For the all-items PPI, we back-extend (1981m1 to 2020m12) using WPI. We construct a seasonally adjusted counterpart using the X-13ARIMA-SEATS program.
All seasonally adjusted and unadjusted CPIs are routinely subject to revision for up to three months after original publication, to reflect late reports and corrections received from respondents. A final estimate isissued three months after initial publication.
Seasonally adjusted monthly data for the previous five years are revised concurrent with the April CPI.
Major program changes are made upon the CPI rebasing, every five years. The weights will be updated annually from 2018. As soon as the rebasing process is finished, the new results will be announced in the upcoming February with data of January.
The CPI is not a cost-of-living index (COLI). As defined by the UN and ILO, a CPI measures expenditure for a fixed market basket, whereas a COLI measures expenditure to achieve a fixed level of utility. The latter includes goods and services received free as in-kind transfers from government or NPISHs, and accounts for substitution effects.
