Introduction<\/strong><\/h2>\n

India\u2019s new National Accounts Statistics (NAS), with 2022-23 as the base year, estimates manufacturing GVA at \u20b938.6 lakh crore in 2023-24. However, an alternative estimate using Annual Survey of Industries (ASI) and Annual Survey of Unincorporated Sector Enterprises (ASUSE) gives only \u20b927.4 lakh crore, creating a 40.9% gap and raising questions about the official estimate.<\/p>\n

How is Manufacturing GVA Estimated?<\/strong><\/h2>\n
    \n
  1. Two parts of manufacturing:<\/strong> Manufacturing includes the organised factory sector<\/strong> and unincorporated or informal units<\/strong>, such as small factories, workshops and household enterprises.<\/li>\n
  2. Factory-sector data through ASI:<\/strong> The Annual Survey of Industries (ASI)<\/strong> provides production, employment and value-added data for registered manufacturing factories.<\/li>\n
  3. Informal-sector data through ASUSE:<\/strong> The Annual Survey of Unincorporated Sector Enterprises (ASUSE)<\/strong> covers manufacturing units outside the corporate and factory sectors.<\/li>\n
  4. Combined coverage of ASI and ASUSE:<\/strong> Together, ASI and ASUSE capture almost the entire manufacturing sector, making their combined gross value addition(GVA) useful for checking official estimates.<\/li>\n
  5. MCA-21 as a major source:<\/strong> The NAS uses MCA-21 company balance-sheet data<\/strong> to estimate organised manufacturing GVA, replacing part of ASI-based estimation since the previous revision.<\/li>\n
  6. Changes in the 2022-23 base-year revision:<\/strong> The 2022-23 base-year series released in 2026<\/strong> retains MCA-21, but fine-tunes the method through segregation of activities in multi-activity companies<\/strong> and uses ASUSE instead of earlier five-yearly NSS surveys.<\/li>\n
  7. Changes in price estimation:<\/strong> The new series uses double deflation where suitable<\/strong>, replacing single deflation to improve the measurement of manufacturing GVA at constant prices.<\/li>\n<\/ol>\n

    The Scale and Source of the GVA Gap<\/strong><\/h2>\n
      \n
    1. Official manufacturing GVA:<\/strong> The new NAS estimates manufacturing GVA at \u20b938.6 lakh crore in 2023-24 at current prices<\/strong>, equal to about 14% of aggregate GVA<\/strong>.<\/li>\n
    2. Alternative estimate:<\/strong> The ASI and ASUSE datasets together produce an alternative estimate of \u20b927.4 lakh crore<\/strong>, which is \u20b911.2 lakh crore or 40.9% below<\/strong> the official figure.<\/li>\n
    3. Gap cannot be treated as minor:<\/strong> Such a large difference between estimates based on official datasets cannot be explained simply by small definitional or methodological variations<\/strong>.<\/li>\n
    4. Informal sector is not the main source:<\/strong> ASUSE is common to both estimates, while the unincorporated sector accounts for only 13.9% of total manufacturing GVA<\/strong>.<\/li>\n
    5. Organised sector creates the main difference:<\/strong> The major source of the gap therefore lies in organised manufacturing<\/strong>, where the NAS relies on MCA-21 company financial data.<\/li>\n
    6. Enterprise approach behind the shift:<\/strong> The 2011-12 base-year revision<\/strong> introduced the MCA-21-based enterprise approach to capture activities of manufacturing companies beyond individual factory establishments.<\/li>\n
    7. Continuation in the new series:<\/strong> The 2022-23 base-year revision of 2026<\/strong> continues this MCA-21-based approach with limited methodological changes, making its treatment central to the present GVA debate.<\/li>\n<\/ol>\n

      Can Residual Workers and Companies Explain the Gap?<\/strong><\/h2>\n
        \n
      1. Employment-based validation:<\/strong> Potential manufacturing output can be estimated from employment by applying technical ratios<\/strong> derived from ASI and ASUSE data.<\/li>\n
      2. PLFS employment estimate:<\/strong> The Periodic Labour Force Survey (PLFS) 2023-24<\/strong> estimates 697.5 lakh manufacturing workers<\/strong>, compared with 532.9 lakh workers<\/strong> represented in ASI and ASUSE.<\/li>\n
      3. Residual workers:<\/strong> PLFS estimates 697.5 lakh workers<\/strong>, while ASI and ASUSE account for 532.9 lakh<\/strong>, leaving 164.6 lakh residual workers,<\/strong> may therefore explain part of the GVA gap.<\/li>\n
      4. Employment data are not identical:<\/strong> PLFS, ASI and ASUSE use different employment definitions and collection methods, but PLFS still provides a useful reference for checking the official GVA.<\/li>\n
      5. Residual MCA-21 companies:<\/strong> MCA-21 has 3,51,152 active private non-financial manufacturing companies<\/strong>, while ASI covers 78,618 private companies<\/strong>, leaving 2,72,534 residual companies<\/strong> outside ASI coverage.<\/li>\n
      6. Uncertain operational status:<\/strong> A 2019 NSSO Technical Report<\/strong> found that 36% of MCA-21 companies<\/strong> in a services-sector exercise were closed, untraceable, unwilling to provide information or misclassified.<\/li>\n
      7. Estimated working residual companies:<\/strong> Since 36% of the 2,72,534 residual companies<\/strong> may be non-working, the remaining 64%<\/strong>, which is equal to 1,74,422 companies<\/strong>, are considered potentially working.<\/li>\n
      8. GVA of residual companies:<\/strong> The technical ratios for private non-factory companies<\/strong>, derived from unit-level ASI data<\/strong>, are applied to the 1,74,422 potentially working residual companies<\/strong>, giving 15.6 lakh workers and <\/strong>\u20b91.9 lakh crore GVA<\/strong>.<\/li>\n
      9. GVA of remaining workers:<\/strong> The remaining 149.1 lakh residual workers<\/strong> are considered part of the unincorporated manufacturing sector<\/strong>; applying the GVA-per-worker ratio derived from ASUSE data<\/strong> gives \u20b91.7 lakh crore GVA<\/strong>.<\/li>\n
      10. Total residual contribution: <\/strong>The \u20b91.9 lakh crore GVA from residual companies and \u20b91.7 lakh crore from the residual unincorporated sector together give \u20b93.6 lakh crore.<\/li>\n
      11. Potential manufacturing GVA:<\/strong> Adding \u20b93.6 lakh crore of potential GVA to the \u20b927.4 lakh crore alternative estimategives \u20b931.0 lakh crore.<\/li>\n<\/ol>\n

        The Unexplained Gap: Methodological Concerns<\/strong><\/h2>\n
          \n
        1. Large gap still remains:<\/strong> After adding \u20b93.6 lakh crore<\/strong> to the \u20b927.4 lakh crore alternative estimate<\/strong>, potential GVA reaches \u20b931.0 lakh crore<\/strong>, which is \u20b97.6 lakh crore below the official <\/strong>\u20b938.6 lakh crore estimate; this difference is 24.5% of the potential GVA.<\/strong><\/li>\n
        2. Unexplained GVA:<\/strong> The potential GVA of \u20b931.0 lakh crore<\/strong> accounts for 80.3% of the official <\/strong>\u20b938.6 lakh crore GVA<\/strong>, leaving \u20b97.6 lakh crore, or 19.7%, unexplained<\/strong>.<\/li>\n
        3. NSO\u2019<\/strong>s explanation:<\/strong> The NSO argues that ASI may miss value addition occurring outside factories, such as head-office, R&D, marketing and distribution activities<\/strong>, which MCA-21 may capture.<\/li>\n
        4. Evidence challenges the ASI explanation:<\/strong> Field-based evidence suggests ASI already captures employment, investment and value addition<\/strong> from activities outside factory premises when they belong to the enterprise.<\/li>\n
        5. Possible MCA scaling-up problem:<\/strong> Another explanation is that MCA-21 sample estimates may be scaled up to an uncertain universe of active companies<\/strong>, whose actual size and composition are unclear.<\/li>\n<\/ol>\n

          Way Forward<\/strong><\/h2>\n
            \n
          1. Open MCA-21 data:<\/strong> The Ministry of Corporate Affairs (MCA-21) data<\/strong> used for manufacturing GVA estimation should be made available for independent examination.<\/li>\n
          2. Disclose estimation methods:<\/strong> The NSO should provide detailed methods<\/strong> used to convert MCA-21 company data into manufacturing GVA estimates.<\/li>\n
          3. Enable independent validation:<\/strong> Researchers should be able to compare MCA-21, ASI, ASUSE and PLFS data<\/strong> to verify the official manufacturing GVA estimate.<\/li>\n
          4. Resolve the methodological dispute:<\/strong> Independent scrutiny can establish whether the higher MCA-21-based estimate reflects better production coverage or possible overestimation<\/strong>.<\/li>\n
          5. Restore confidence in official data:<\/strong> Greater transparency and independent verification can strengthen public confidence in GDP and sectoral GVA estimates<\/strong>.<\/li>\n<\/ol>\n

            Conclusion<\/strong><\/p>\n

            The new 2022-23 base-year series<\/strong> gives manufacturing GVA of \u20b938.6 lakh crore<\/strong>, but the ASI-ASUSE estimate gives only \u20b927.4 lakh crore<\/strong>. Even after accounting for residual companies and workers, \u20b97.6 lakh crore remains unexplained<\/strong>. The key issue is whether MCA-21 improves coverage or causes overestimation. Opening data and methods for independent verification<\/strong> is therefore essential to establish the estimate\u2019s credibility.<\/p>\n

            Question for practice:<\/strong><\/p>\n

            Examine the reliability of India\u2019s manufacturing sector GVA estimates and the reasons behind the gap between official and alternative estimates.<\/p>\n
