📖 History: From Physics to Planning India’s Future
Born into an intellectually prominent Bengali family, Mahalanobis was nurtured in an environment of education and liberal ideas. After completing his early education at Presidency College, he went to Cambridge to study physics, but fate had other plans. There, he stumbled upon statistics — a field that was still in its infancy.
Upon returning to India, he started using statistical techniques to solve complex social and economic problems. This passion led to the establishment of the Indian Statistical Institute (ISI) in 1931.
During India’s formative years, he played a crucial role in planning the economy and advised Nehru on various developmental models. His idea of a data-driven economy was revolutionary at a time when empirical data collection was rare in Indian policy circles.
📊 Significance of His Contributions
🔹 1. Father of Indian Statistics
He introduced modern statistical methods to India, making the subject integral to governance and development.
🔹 2. Mahalanobis Distance
A statistical formula that helps detect similarities between datasets. It’s still widely used in machine learning, AI, and data science.
🔹 3. Indian Statistical Institute (ISI)
ISI, founded in 1931, is globally renowned for research and teaching in statistics and computer science.
🔹 4. National Sample Survey (NSS)
He pioneered large-scale surveys in India. The NSS became the backbone of Indian economic and demographic analysis.
🔹 5. Planning Commission Advisor
He designed India’s Second Five-Year Plan, focusing on heavy industrialization — a key element in India’s economic growth.
