Data Revision: India - GDP(E) SA - Method
Monday, 10 Dec 2018 15:16 ET
By Katie Cristofano
December 2018 -- For the quarterly detailed expenditure approach to gross domestic product for India, we produce seasonally adjusted supplements, and have switched from X-12 to X-13 (44 quarterly series, revised from 1996).

Motivation: The Ministry of Statistics and Programme Implementation (MOSPI) reports GDP by expenditure in current and constant prices, but only from 2011Q2 and in not seasonally adjusted (NSA) terms.  Previously, we created our seasonal factors using the X-12 ARIMA seasonal adjustment program; we are now incrementally migrating to the X-13 ARIMA program, which is newer and usually produces superior results.

Response: All NSA GDP(E) series have been re-extended prior to 2011Q2. Our seasonal factors have been recalculated using the X-13 program, and the SA series have been recomputed. What you will see:

  • All 22 GDP(E) NSA series revised, from 1996Q2 to 2011Q1.
  • All 22 GDP(E) SA counterparts revised, from 1996Q2 to 2018Q2.

Properties: Properties are otherwise unchanged. Series start as early as 1996Q2. Expect our SA supplements to be revised with each update. 

The series reside in the historical catalog (India » National accounts » by Expenditure » Quarterly) and include, for example: 

  • NALEGDPUQ.IIND = National Accounts: Expenditure approach - GDP, (10 Mil. INR, NSA)
  • NALETBAQ.IIND  = Trade balance, (10 Mil. INR, SAAR)
  • NACEGCFUQ.IIND = Gross capital formation, (10 Mil. 2011-2012 INR, NSA)
  • NACEEXAQ.IIND  = Exports, (10 Mil. 2011-2012 INR, SAAR)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.  


  1. Extend reported NSA GDP(E) components, prior to 2011Q2, using their reported predecessors. 
  2. Compute NSA trade balance and gross capital formation as identities.
  3. Adjust GDP by expenditure components individually, using the U.S. Census Bureau's X-13 ARIMA program.
  4. Compute SA trade balance, statistical discrepancy, and changes in inventories as identities.
