The Indian Statistical Institute (ISI), based in Calcutta (now Kolkata), is one of the oldest and most prestigious institutions in India. Renowned globally for its contributions to the fields of statistics, mathematics, computer science, and data science, ISI is a hub of cutting-edge research and education. Established in 1931 by the visionary statistician Professor Prasanta Chandra Mahalanobis, ISI has significantly contributed to both the academic and practical applications of statistics, especially in India. Over the decades, it has played an instrumental role in shaping the landscape of research and education in statistics and allied subjects.

History and Evolution

The inception of ISI traces back to Mahalanobis’ keen interest in statistical methods, particularly their application to societal and economic problems. The institute was founded in Kolkata with the aim of creating a space where statistical research and the application of statistical techniques could be rigorously developed. From its early days, ISI worked on various national-level projects, including the National Sample Survey and the Indian Census, leveraging the power of statistics to solve real-world problems.

ISI’s importance grew exponentially after India’s independence in 1947, with the country realizing the need for robust statistical data to drive development. Over the years, ISI has evolved to become a global center for statistical research, training, and applied statistics, with a strong focus on interdisciplinary collaboration.
