The Big Picture
Prelims · HighMains · High

Principal Secretary to PM, PK Mishra, announced at the 20th Statistics Day that the statistical system is being comprehensively overhauled after decades of decline. The reforms, driven by the PMO since 2020, have already resulted in updated GDP, CPI, and WPI series with new base years, and a push to treat administrative data (e.g., GST) as a strategic national asset. This directly impacts the accuracy of India's economic data, a topic frequently tested in prelims and mains.
