Household Expenditure Survey
Based on the household expenditure patterns obtained from the Household Expenditure Survey (HES) conducted during October 2014 to September 2015, the C&SD has updated the base period and expenditure weights for compiling the CPIs. After rebasing, the CPI(A), CPI(B) and CPI(C) continue to reflect the price changes faced by households in the relatively low, medium and relatively high expenditure ranges respectively. Likewise, the Composite CPI continues to reflect the impact of the changes in consumer prices on the household sector as a whole. The expenditure brackets for the 2014/15-based CPI series are as follows :
