India’s GDP Revisions: NSO Reform and Key Figures
Why in the news
The National Statistical Office shortened its GDP revision cycle, yet big gaps between early and final estimates continue to raise data-credibility questions.
Key facts
- NSO reform: six to five iterations; final estimate in two years instead of three.
- Aim: simpler reporting and timelier GDP numbers.
- Possible causes of gaps: delayed data from agencies and state-owned firms, overestimation in weak years, underestimation in strong years, and more optimistic advance estimates before elections.
| Year | Revision |
|---|---|
| 2016-17 (demonetisation) | 7.1% revised up to 8.3% |
| 2018-19 (election year) | 7.2% revised down to 6.5% |
| 2020-21 (COVID) | Final growth 1.9 percentage points above the first estimate |
| 2023-24 | FAE 7.3% to First Revised Estimate 9.2%; manufacturing growth doubled |
| 2024-25 | Second Advance Estimate 6.5% (earlier 6.4%) |
Implications
- Fiscal deficit for 2023-24: 5.6% to 5.5% of GDP; 2024-25 target 4.7%.
- Modi government’s second-term growth now reads 5% against 4.6% earlier.
- Questions on data reliability and transparency remain.
Way forward
- Reduce revision size and shorten the timeline to match global practice.
- Improve data collection from agencies and firms.
- Raise transparency to prevent political influence.
Exam angle
- Body: National Statistical Office (NSO).
