IIP Monthly
Comparison of economic performance over time is a key factor in economic analysis and a fundamental requirement for policy-making
Short-term indicators play an important role in this context by providing such comparison indicators
Among the short term indicators, the Index of Industrial Production (IIP) has historically been one of the most well-known and well-used indicators. The all India IIP is a composite indicator that measures the short-term changes in the volume of production of a basket of industrial products during a given period with respect to that in a chosen base period
It is compiled and published monthly by the Central Statistics Office (CSO) with a time lag of six weeks from the reference month
The all-India IIP provides a single representative figure to measure the general level of industrial activity in the economy on a monthly basis
It is used by Government agencies/ departments especially the Ministry of Finance, the Reserve Bank of India, etc. for policy purposes
The all-India IIP forms a crucial input for compilation of Gross Value Added of Manufacturing sector in Gross Domestic Product of the country on quarterly basis
The Summary level IIP comprises Mining (14.3725% weight), Manufacturing (77.6332%), Electricity (7.9943%) and the Overall IIP

Initially, 2009-10 was recommended as the base year for the new series of IIP and laid down detailed methodologies of item selection, computation of weights with 2009-10 as base year. However, later the WG took note of the fact that it was already decided that base year of the revised series of National Accounts would be 2011-12. Further the base year of new series of Consumer Price Indices (CPI) was already decided to be 2012 (calendar year). Since it is advisable to consider the same base for all macroeconomic aggregates, the WG recommended shifting the base year of IIP to 2011-12
The National Industrial Classification (NIC) is an indigenized version of the International Standard Industrial Classification (ISIC) developed by the United Nations Statistics Division (UNSD). Due to the rapid changes in the industrial structure of the country, it is necessary to undertake revisions of the industrial classification. NIC 2004 version used in IIP with base 2004-05 was based on ISIC version 3.1, while the NIC 2008 version adopted in the new series of IIP with base 2011-12 is based on the revised ISIC 4 version. Between the two versions of NIC, several changes in structure of classification has taken place, by merging/ splitting of existing industries and addition of new industries based on the new industrial pattern of the economy and new industries assuming significance
