Calculation of CPI


Calculation of CPI
                The Labour Bureau has been compiling and maintaining three different series of Consumer Price Index numbers viz. (i) Consumer Price Index Numbers for Industrial Workers (CPI-IW) on base 2001=100, (ii) Consumer Price Index Numbers for Agricultural Labourer on base 1986-87=100, (iii) Consumer Price Index Numbers for Rural Labourer on base 1986-87=100.

These index numbers measure a temporal change in prices of fixed basket of goods and services consumed by the target groups and are compiled on the basis of the prices of selected goods and services which are collected every week/month and the weights assigned to them. Weights to the selected items are assigned on the basis of the expenditure incurred on them as revealed by the surveys conducted for the purposes.

The index numbers for centre/state are compiled in several stages i.e. Sub-group, Group and General level. These centre/state level indices are then weighed to work out all-India indices.

The weights (Group / Sub-group wise) under  Consumer Price Index for Industrial Workers on base 2001=100 and Consumer Price Index Numbers for Agricultural Labourer / Rural Labourer on base 1986-87=100 are given at Annexure.

The services like education, health/medicine, transportation are included in the compilation of all three Consumer Price Index Numbers. The details of the weights assigned to services like education, health/medicine, transportation, etc. are given in Annexure.

There is substantial increase in the weights attached to services like education, health/medicine,transportation in successive series of Consumer Price Index number for Industrial Workers which is revealed from the statement given below:
