About the Consumer Price Index (CPI)
The CPI is designed to measure the average price changes of a fixed basket of consumption goods and services commonly purchased by resident households over time. The CPI is widely used and analysed as a measure of consumer price inflation. It measures price movements (i.e., change in prices) but not absolute price levels at a point in time.
The weighting pattern for the 2024-based CPI was derived from the expenditure values obtained from the Household Expenditure Survey (HES) 2023, and updated to 2024 values by taking into account price changes between 2023 and 2024.
The CPI covers only household consumption expenditure incurred by resident households, which refer to households where the household reference person is a Singapore Citizen or Permanent Resident. It excludes non-consumption expenditure such as loan repayments, income taxes, purchases of houses, shares, and other financial assets etc.
A total of 6,800 brands/ varieties are included in the 2024-based CPI basket and they are classified into ten main expenditure divisions based largely on the Classification of Individual Consumption According to Purpose (COICOP). The total number of outlets selected for pricing is about 4,500.
