Two types of data are required for compiling the CPI, they are the expenditure weights of consumer goods and services; and the price movements of consumer goods and services.

A Monthly Retail Price Survey is conducted by the C&SD to gather information on prices of pre-selected items from different types of retail outlets and service 5 providers throughout the territory. Price data are collected mainly by field visits, supplemented by telephone and postal enquiries.

The price index for each individual commodity or service item for the month concerned, which reflects the price change of the item since the base period, is first obtained. This is done by comparing its price in that month to the price in the base period.

No revision is made after the release of the index numbers.
