Notes: The year-on-year rate of change in the Consumer Price Index (CPI) is an indicator of inflation affecting

consumers.

Figures are derived based on the 2009/10-based CPI series. The year-on-year rates of change before October 2010 were derived using the index series in the base periods at that time (for instance the 2004/05-based index series), compared with the index a year earlier in the same base period. (1) The CPI(A), CPI(B) and CPI(C) respectively cover some 50%, 30% and 10% of households in Hong Kong. The average monthly household expenditure (in HK$) of these groups during the base period (i.e. Oct. 2009-Sep. 2010) were $4,500-$18,499, $18,500-$32,499 and $32,500-$65,999 respectively. Taking into account the impact of price changes since the base period, the monthly household expenditure ranges of the CPI(A), CPI(B), and CPI(C) adjusted to the price level of 2011 are broadly equivalent to $4,800-$19,600, $19,600-$34,400 and $34,400-$69,900 respectively, and that of the Composite CPI is broadly equivalent to $4,800-$69,900. The Composite CPI is compiled based on the expenditure patterns of all these households taken together.
