Expert Group unveils report on base revision of Wage Rate Index (WRI) to 2016=100 from base 1963-65=100.

Prof. S.P.Mukherjee, Chairman of Expert Group on Minimum Wages & National Floor Wages, Dr G.C.Manna, Chairman of Technical Advisory Committee of Wage Rate Index, Shri DPS Negi, Principal Advisor, Ministry of Labour & Employment, Ms. Sibani Swain, Additional Secretary, Ministry of Labour & Employment, Ms. Vibha Bhalla, Joint Secretary, Ministry of Labour & Employment and Shri I.S. Negi, DGLB & other members of Expert Group released the new series of Wage Rate Index (WRI) with base year 2016=100, being compiled and maintained by Labour Bureau, an attached office of Ministry of Labour & Employment.  The new series of WRI with base 2016=100 will replace the old series with base 1963-65=100.

Shri DPS Negi, Principal Advisor, Ministry of Labour & Employment lauded the efforts of Labour Bureau for their steadfastness and exemplary role which have finally culminated in the release of updated series of WRI. While admiring the efforts, he also stressed upon the need for data on all aspects of labour as it will be crucial to serve as inputs in policy making and this justifies the existence of an organization like Labour Bureau. With the ever increasing importance of data in the times to come coupled with the fact that India is a labour abundant nation, a dedicated organization for labour and price statistics like the Labour Bureau merits strengthening.

The Report on “New Series of Wage Rate Index (Base 2016=100)” is an important publication meant to give insights into the concepts, definitions and methodology related to the new series of WRI with 2016 as base year. This will serve as a useful reference book for researchers, academicians, scholars and all other stakeholders of WRI.

The Government of India periodically revises the base year for major economic indicators to reflect the changes in the economy and to capture the wage pattern of workers.

Thus, as per the recommendations of  International Labour Organization (ILO), National Statistical Commission (NSC) etc. the base year of Wage Rate Index numbers has been revised from 1963-65=100 to 2016=100 by the Labour Bureau, Ministry of Labour & Employment to enhance the coverage and to make index more representative.

The new series of Wage Rate Index i.e. 2016=100 replaces the old series (1963-65=100) which is almost six decades old, has increased the scope and coverage in terms of number of  industries, sample size, occupations under selected industries, weightage of industries etc. Technical Advisory Committee (TAC) on WRI constituted by MoL&E under the chairmanship of Dr. G.C. Manna, former DG, CSO, provided all technical inputs for construction  of New WRI Series.

Prof. S.P.Mukherjee and other Members of the Expert Group on Minimum Wages & National Floor Wages were of the opinion that this base revision of the Wage Rate Index 2016=100 will play a very critical role in coming out with the Minimum Wages & National Floor Wages along with other parameters which will be decided in due course of time by the Expert Group. 

 

Key Highlights

The New WRI Series with base 2016=100 would be compiled twice a year on point-to-point half yearly basis, as on 1^st January and 1^st July of every year. Some of the major improvements made under the new series of WRI (2016=100) vis-à-vis old series (1963-65=100) are as under:

• The weighting diagram in the new WRI series has been prepared from the results of the Occupational Wage Survey (Seventh) round.
• A total of 37 industries have been covered in the new WRI basket (2016=100) as against 21 industries in the 1963-65=100 series.
• The selected 37 industries in the new series are categorized as 30 industries from Manufacturing sector, 4 industries from Mining Sector and 3 industries from Plantation Sector as compared to 14 industries from Manufacturing sector, 4 industries from Mining Sector and 3 industries from Plantation Sector in the old series.
• In the new WRI basket, the current wage data has been collected from 2881 units under 37 selected industries as against to 1256 units under 21 industries  in the old series of WRI.
• About 700 occupations have been covered under 37 selected industries in new series of WRI (2016=100).

Weighting Pattern

• The weights used in WRI Series with base 1963-65=100 were the base year estimated employment figures in respective occupations in each selected industry.
• The weights adopted for the construction of WRI numbers under New WRI Series (Base: 2016=100) are the base year estimated employment figures in the respective occupations in each selected industry. The weighted average of the occupation level indices in an industry, weights being the base year estimated total employment bill in each occupation, gives WRI at the industry level. Similarly, the weighted average of the industry/Sector level indices, weights being the base year estimated total employment bill in each industry/sector, gives Sectoral/All-India Index.
• Sector wise major changes in weights, number of industries and sample units between 1963-65=100 series and 2016=100 series are as under:

Sector	No. of Industries		Weights		Sample Units
	1963-65	2016	1963-65	2016	1963-65	2016
Manufacturing	14	30	48.78	82.57	923	2627
Mining	4	4	17.01	11.23	110	163
Plantation	3	3	34.21	6.20	223	91
All	21	37	100.0	100.0	1256	2881

 

The sector level weights under new series has changed in comparison to old series (1963-65=100). The weight of Manufacturing sector has increased substantially over time whereas the weight of Plantation sector and Mining sector has declined under 2016=100 series vis-à-vis 1963-65=100 series.
