      Index of Industrial Production
           Index of Industrial Production (IIP) is released by CSO every month in the form of Quick
      Estimates with a time-lag of 6 weeks as per the Special Data Dissemination Standard (SDDS)
      norms of IMF. The base year of all-India IIP was revised from 2004-05 to 2011-12 and the new
      series was launched in 2017. IIP is compiled using secondary data received from 14 source
      agencies in various ministries/departments or their attached/subordinate offices. Apart from
      breakup of the index in three sectors, viz., mining, manufacturing and electricity, the estimates
      are also simultaneously released as per use-based classification viz., primary goods, intermediate
      goods, infrastructure construction goods and consumer durables and consumer non-durables. The
      Quick Estimates are subsequently revised as first Revision after one month from release on
      receipt of updated production data from the 14 source agencies. Subsequently, the indices are
      again revised after two months from first Revision. The major source of data for IIP is the
      Department of Industrial Policy and Promotion that supplies data for 322 out of 407 item groups
      with a weight of 47.54 per cent in overall IIP.
