National Statistics Day in India was first celebrated in 2007, following a Gazette notification on 5th June 2007, which declared 29th June—the birth anniversary of PC Mahalanobis—as Statistics Day. It was categorised as a Special Day of National Importance to raise awareness about the significance of statistics in nation-building.
The decision to dedicate a day to statistics stemmed from the invaluable role that statistical research plays in formulating effective government policies, monitoring socio-economic indicators, and measuring national progress.

The primary reason for celebrating National Statistics Day in India is to pay tribute to the statistical genius PC Mahalanobis, who not only founded the Indian Statistical Institute (ISI) in 1931 but also revolutionised economic planning in India. He was instrumental in introducing statistical methods for efficient data collection and analysis, especially in agricultural and population studies.
On the other hand, it aims to create public awareness, especially among the youth, about the relevance of statistics in everyday life and their role in driving national development.
The National Statistics Day theme for 2025 is “75 Years of National Sample Survey”, marking the significant contribution of the National Sample Survey in providing reliable and timely statistical data that supports evidence-based decision-making and governance in India.
Born on June 29, 1893, in Kolkata, Prasanta Chandra Mahalanobis was a visionary whose work shaped modern statistics in India. His creation, the Mahalanobis distance, is still widely used in multivariate analysis and pattern recognition.
His work laid the foundation for the modern statistical system in India, enabling data-based policymaking and the institutionalisation of national surveys and statistical standards.
Each year, National Statistics Day is celebrated on 29th June across various levels—national, state, academic, and research institutions. The celebrations typically include:
A notable development is the launch of the e-Sankhyiki portal and Central Data Repository, platforms designed to enhance transparency and accessibility of statistical data in India.
The importance of National Statistics Day 2025 lies in its role in spreading awareness about:
National Statistics Day 2025 also serves as an opportunity to review and refine the methodologies used in the collection, processing, and dissemination of data by official agencies.
Since its inception in 2007, National Statistics Day has become a cornerstone in promoting statistical literacy and evidence-based governance in India. From launching key data repositories to honouring statistical pioneers, each year’s celebration reaffirms India’s commitment to scientific planning and transparent policymaking.
With initiatives like Digital India, the role of statistics has become even more critical in handling big data, AI integration, and digital governance, making this observance more relevant than ever.
National Statistics Day stands as a tribute to the visionary contributions of PC Mahalanobis and serves as a national platform to emphasize the vital role of statistics in shaping modern India. As the 19th Statistics Day approaches on 29th June 2025, it continues to remind us that “data is the new oil,” powering policy decisions, social programs, and economic strategies.
By engaging the youth, fostering innovation, and promoting transparency through reliable data, National Statistics Day in India contributes meaningfully to inclusive, informed, and sustainable national development.
