Quick Revision: The Index of Services Production (ISP) is a volume-based index measuring real growth in the services sector, excluding price effects, and is a critical input for GDP estimation and policy formulation.

Why is this in the news?

This initiative is aimed at improving the accuracy, comprehensiveness, and timeliness of economic data, which is critical for assessing the performance of the services sector—a dominant and fast-growing component of India’s Gross Domestic Product (GDP). The proposed changes reflect the need to align India’s statistical framework with global best practices and address emerging economic realities.

Background

• The Index of Services Production (ISP) is a key economic indicator that measures the growth of the services sector in India, which contributes over 50% to the country’s GDP.
• The ISP is compiled and published monthly by the National Statistical Office (NSO), under the Ministry of Statistics and Programme Implementation (MoSPI).
• The current ISP framework was last revised in 2011–12, and its coverage has not been significantly updated to reflect structural changes in the economy, such as the rise of digital services, e-commerce, and new-age industries.
• The services sector in India has grown rapidly, with sub-sectors like IT-BPM, financial services, and professional services gaining prominence, necessitating a more granular and dynamic measurement framework.
• The Reserve Bank of India (RBI) and other policymakers rely on the ISP for monetary policy decisions, inflation targeting, and assessing economic growth trends.
• Global best practices, including those recommended by the United Nations Statistical Division (UNSD) and International Monetary Fund (IMF), emphasize the need for timely, accurate, and comprehensive economic indicators to support informed decision-making.

What is the Index of Services Production (ISP)?

• The ISP is a statistical measure that tracks the real growth of the services sector in India, excluding the impact of price changes (i.e., it is a volume-based index).
• It is one of the three principal indices used to compile Gross Value Added (GVA) in the National Accounts Statistics, alongside the Index of Industrial Production (IIP) and the Index of Agricultural Production (IAP).
• The ISP covers 15 major service sub-sectors, including trade, hotels and restaurants, transport, storage, communication, banking and insurance, real estate, professional services, and public administration.
• The index is compiled using data from various sources, including administrative records, surveys, and industry-specific indicators, and is published with a lag of approximately 45 days after the reference month.
• The current base year for the ISP is 2011–12, which means the index is calculated using the prices and structure of the economy from that period, potentially leading to outdated weightages and coverage gaps.
• The ISP is used by policymakers, economists, and businesses to assess the health of the services sector, which is a critical driver of employment and economic growth in India.
• The index is also a key input for the compilation of GDP estimates, as the services sector accounts for over 50% of India’s GDP.
• The proposed expansion aims to include newer service sub-sectors such as digital services, e-commerce, and other emerging industries, while also updating the weightages to reflect their growing contribution to the economy.
