How is this data produced?
The CPI measures the cost of purchasing a constant, representative 'basket' of goods and services. The quantity and quality of goods in the basket are kept constant, so that changes in the cost of the basket are purely due to price changes. The changes in the cost of this basket represent the rate of inflation. The difference between the CPI and core CPI (this dataset) is that core CPI excludes items with volatile prices or government-administered prices. This is usually taken to be a better gauge of the 'underlying' or long-run trend in the price level. For a deeper understanding of the methodology, please refer to the Technical Notes. Finally, it should be noted that Malaysia's CPI classification is deliberately consistent with the United Nations Classification of Individual Consumption According to Purpose (COICOP) to ensure international comparability.
What caveats I should bear in mind when using this data?
The core CPI is not computed for the 'Alcoholic Beverages and Tobacco' category because all items in this category have their prices administered by the government, and are thus excluded from core CPI calculations.
