Three types of Consumer Price Index Numbers maintained by Labour
Bureau
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:
