The PSA said the Consumer Price Index measures changes in the average retail prices of a fixed basket of goods and services commonly purchased by households relative to a base year.
The base year or base period is the reference period at which the index number is set to 100.
The PSA said inflation rate refers to the annual rate of change, or year-on-year change, in the CPI expressed as a percentage.
A positive inflation rate means prices increased compared with the previous year, while a negative rate means prices decreased compared with the previous year.
The agency said a positive but lower inflation rate compared with the previous month means prices still increased year on year, but at a slower pace.
The CPI for bottom 30% income households measures changes in prices of commodities commonly purchased by families in the bottom 30% income decile.
The PSA said the price collection and CPI computation process for the bottom 30% income households is the same as that for all income households, but it uses a separate market basket and weights.
