- Strengthened data collection mechanisms improve measurement of industrial output.
- Ministry of Commerce and Industry updated the Wholesale Price Index (WPI) series.
- More accurate IIP and WPI improve estimation of the GDP Deflator.

Introduction of Producer Price Index (PPI) & Way Forward
- Government introduced a new Producer Price Index (PPI).
- PPI is expected to replace WPI within the next five years.

- Reflects global best practices followed by advanced economies.
- Reforms are likely to improve India's data-quality rating by the International Monetary Fund.
- Timely completion and release of the Census of India remains the next critical step for strengthening India’s statistical ecosystem and evidence-based policymaking.
Conclusion
The statistical reforms mark a significant step towards creating a modern, transparent, and globally aligned data ecosystem. Accurate measurement of growth, inflation, and production enhances policy effectiveness, investor confidence, and public trust. However, the benefits of these reforms will be fully realized only through timely data releases, especially the Census, and continued methodological improvements.
