India proposes an Index of Services Production (ISP) to address a major data gap in its dominant services sector, which contributes over 50% to GVA. While crucial for better economic analysis and policy, constructing an ISP faces significant challenges. These include the sector's heterogeneous nature, vast informal chunk, lack of consistent administrative data, and difficulties in choosing appropriate price deflators. Despite these hurdles, the author argues that even an imperfect ISP with patchy coverage would serve a valuable purpose as a directional indicator, providing essential insights and allowing for future refinement. Implementation is urged without waiting for perfection.
