The Department of Pure and Applied Mathematics at Alliance University observed National Statistics Day on 28 June 2025. The event was held to honour the legacy of Professor Prasanta Chandra Mahalanobis, known for his contribution to the field of statistics in India.  This year’s theme, "Driving Change with Quality Statistics and Data for Everyone", focused on the role of inclusive and accessible data in shaping national development. 

Insights from the Chief Guest 
Shri Saji George, Deputy Director General of the National Sample Survey Organisation (Field Operation Division), Bangalore, was invited as the Chief Guest. In his address, he reflected on the significance of the NSSO’s diamond jubilee and spoke about the increasing value of statistics in a world shaped by technological change, environmental shifts, health concerns, and economic developments. He emphasised that quality data—collected, analysed, and interpreted well—can guide policymakers, educators, entrepreneurs, and citizens to make informed choices. He also noted the importance of integrating new tools like artificial intelligence, geospatial analytics, and big data into national systems, while maintaining ethical practices, transparency, and strong local capacity. These efforts, he said, must be supported by the Ministry of Statistics and Programme Implementation (MoSPI). 

Address by the Guest of Honour 
Prof. H J Vaman, former Head of the Department of Statistics at the Central University of Rajasthan and retired Professor at the University of Bangalore, joined the event as the Guest of Honour. He took the audience through the historical journey of statistical education in India, offering insights into its roots and how it has developed over time. He also raised important points about the use of internet-based data and stressed the need for care when relying on online databases, especially in the context of artificial intelligence, where gaps in information remain a concern. 

Reflections from the Department 
Faculty members Dr Subhradev Sen, Dr Suman Kalyan Ghosh, and Dr Usha Arcot, Head of the Department, shared their reflections on the legacy of Professor Mahalanobis. They acknowledged his lasting influence and the relevance of his work in today’s data-centric world. The event saw active participation from research scholars, postdoctoral fellows, and faculty members. It concluded with an expression of interest in future collaboration with the NSSO and other national agencies working in the field of statistics.
