Exclusive interview with former chief statistician of India, Pronab Sen | Double deflation

India’s new gross domestic product (GDP) series, with 2022-23 as the base year, has introduced major methodological changes — from double deflation to improved coverage of the informal sector and segregation of multi-activity firms. While the government has called this a step towards better accuracy, former chief statistician of India, Pronab Sen, says the changes warrant careful scrutiny. In a video interview with Abhijeet Kumar, Sen talks about what matters, where doubts remain, and what ordinary citizens should take away.
