National Statistics Day 2025: Honouring Data for Development

Every year on 29th June, India celebrates National Statistics Day to mark the birth anniversary of Prof. Prasanta Chandra Mahalanobis, a pioneer in the field of modern statistics in India. Known as the father of Indian statistics, Mahalanobis made groundbreaking contributions such as the development of the Mahalanobis Distance and his instrumental role in India’s Five-Year Plans. This day serves as a tribute to his work in economic planning, data science, and institutional building, including the founding of the Indian Statistical Institute (ISI) and the National Sample Survey (NSS).
