India's 20th Statistics Day spotlights 'administrative data', honouring statistician Mahalanobis

On 29 June, the birth anniversary of P.C. Mahalanobis — the father of Indian statistics — MoSPI marks two decades of Statistics Day with a 2026 theme on unlocking the policy potential of administrative data.

What happened

• The Ministry of Statistics and Programme Implementation (MoSPI) will celebrate the 20th Statistics Day on 29 June 2026 at the Dr Ambedkar International Centre, New Delhi.
• The day is observed every year to commemorate the birth anniversary of Professor Prasanta Chandra Mahalanobis, a pioneer in statistics and economic planning.
• Statistics Day aims to create public awareness — especially among the younger generation — about the importance of statistics in socio-economic planning and policy.
• Celebrated with a theme of national relevance since its inception in 2007, the 2026 theme is 'Unlocking the Potential of Administrative Data'.
• The theme underscores leveraging administrative data for evidence-based policymaking, and the need to strengthen data quality, interoperability, integration and governance.

For Prelims

• P.C. Mahalanobis: The 'Father of Indian Statistics' (born 29 June 1893); founded the Indian Statistical Institute (ISI), Kolkata (1931), devised the Mahalanobis distance, and shaped India's planning.
• Feldman-Mahalanobis model: The strategy underpinning the Second Five Year Plan (1956) — emphasising heavy/capital-goods industry for self-reliant growth (the 'Nehru-Mahalanobis' model).
• National Statistics Day: Observed on 29 June (Mahalanobis's birthday); 'World Statistics Day' is separate (observed by the UN every five years).
• MoSPI / NSO: The Ministry of Statistics and Programme Implementation, with the National Statistical Office (NSO), compiles GDP, CPI, IIP, PLFS and conducts the National Sample Survey (NSS) and Census-linked surveys.
• Administrative data: Data generated as a by-product of administration (e.g. tax, GST, registrations, scheme records) — cheaper and timelier than surveys, but needing quality and integration (the 2026 theme).
• National Sample Survey (NSS): Mahalanobis established the NSS (1950) — the backbone of India's socio-economic surveys (consumption, employment, etc.).
• Don't confuse: National Statistics Day (29 June, Mahalanobis) is distinct from World Statistics Day (UN); administrative data complements — it does not replace — survey/census data.
