The National Statistics Office (NSO) in India has proposed the creation of an Index of Service Production (ISP), with 2024-25 set as the base year. This index will utilize aggregated goods and services tax (GST) data to monitor the services sector, which contributes over 50% to the country's gross value added (GVA). Currently, the absence of a dedicated index for services limits the ability to track economic trends effectively. The ISP aims to provide high-frequency information to complement the existing Index of Industrial Production (IIP), which focuses on industrial performance. The NSO's approach paper outlines three primary data sources for the ISP: GST data from the goods and services tax network (GSTN), secondary administrative data from relevant ministries, and the Annual Survey of Incorporated Services Sector Enterprises (ASISSE). The ISP will cover approximately 70% of services GVA and provide disaggregated data at the National Industrial Classification (NIC) 2025 two-digit level. This initiative is crucial for enhancing the analytical and policy framework related to the services sector, which has seen growing demand for timely performance indicators.
