Services Production Index: Measuring Non-Market Activities
Why in News?
On 6 October 2026, MoSPI released an approach paper proposing wider Index of Services Production coverage for education, health and residential care, and public administration and defence.
- The expansion remains proposed; the release invites stakeholder feedback and does not announce implementation of the wider index.
- The existing trial framework covers approximately 60% of services GVA; successful incorporation would raise coverage to approximately 78.4%, according to PIB.
- The gaps concern core government activities, non-market services and GST-exempt services, which cannot all be captured through taxable outward supplies.
- A coverage gap can hide changes in important public services even when the activities already contribute to the economy.
- A wider monthly indicator needs defensible measurement of services delivered, alongside a clear account of the activities still excluded.

- Deflator: removes price changes from nominal values.
- Non-market services: services supplied free or at prices that are not economically significant.
- GVA weights: reflect the relative economic importance of services industries.

Background and Context
What the Proposed Expansion Changes
The issue is which services the monthly indicator can represent, rather than whether the omitted activities exist in the economy.
- Trial compilation began in July 2026 with 2024–25 as the base year, according to PIB. The present framework uses high-frequency administrative records and GST outward-supply data to follow formal services activity.
- Education, human health and residential care, and public administration and defence are the three proposed additions. Their inclusion would extend observation beyond the service activities represented in the initial framework.
- Non-market production includes services supplied free or at prices that are not economically significant. A public classroom can provide education without generating a market sale comparable to a commercial transaction.
- GST exemption and non-market production are different concepts: exemption concerns tax treatment, while non-market status concerns how output is supplied. Neither should be treated as another name for informal employment.
- The MoSPI announcement is an approach-paper consultation, not a completed expansion. Treat its prospective coverage as conditional; do not present the proposed sectors as already incorporated into an operational revised monthly series.
How Production Differs From Money Spent
An output index seeks changes in service volume; rupee values can change because prices change even when the service quantity does not.
- Value-based indicators use sales, revenue or outward supplies. Higher receipts can reflect increased charges rather than additional services, so nominal growth alone cannot establish an equivalent increase in real production.
- A price deflator removes price movements from nominal values to estimate volume changes. The choice must fit the activity: an unsuitable price measure can distort the apparent pace of services growth.
- Quantity indicators directly observe an activity, such as passenger-kilometres in air transport. The official ISP FAQs distinguish these from value-based indicators that need price adjustment to track real output over time.
- Spending is an input-side measure: a larger public wage bill or costlier supplies need not mean more lessons or care delivered. These examples explain measurement limits, not the paper’s final chosen methodology.
- Different services need different indicators because their outputs are heterogeneous. A classroom, a hospital and public administration cannot be reduced to one universal physical unit without explicit aggregation choices and clearly stated limitations.
What a Wider Index Can and Cannot Show
Broader coverage improves representation, but it does not automatically settle quality, informality or the interpretation of public-service performance.
- Administrative data can improve timeliness, but records collected for taxation or programme management need statistical scrutiny. Changes in reporting or coverage must be separated from changes in the underlying activity being measured.
- GST outward supplies help observe taxable transactions; they do not by themselves fill non-market service gaps. Wider coverage requires appropriate additional evidence rather than assuming every service produces a usable tax return.
- GVA-based weights represent industries’ relative economic importance in aggregation, as explained in the FAQs. Do not infer final weights for the proposed additions from headline coverage percentages in the announcement alone.
- Output, quality and outcomes answer different questions. More recorded services do not independently establish better learning or health; an activity index should be interpreted alongside evidence on access, quality and results.
- Informal-sector coverage remains a separate issue. Adding major omitted service areas does not establish universal observation of all providers; readers must check the final framework before treating a broader ISP as the whole services economy.
Way Forward
Make the Measurement Choices Auditable
- Publish sector-specific methods, coverage boundaries and revision rules so users can distinguish measured activity from estimates and assumptions.
- Explain how prices, inputs and output are separated, especially where services lack observable market sales.
- Test comparability over time before combining added sectors with the existing series; disclose breaks caused by revised coverage or reporting.
Conclusion
- The proposed ISP expansion addresses a representation gap, but an approach paper is not an implemented statistical series. Coverage claims must retain that distinction until the revised framework is adopted.
- For analytical answers, separate money spent, services produced and outcomes achieved. A useful high-frequency index measures a defined aspect of activity; it cannot substitute for every assessment of public-service performance.
UPSC Practice Questions
Prelims MCQ 1
With reference to the Index of Services Production, consider the following statements:
- A price deflator helps separate price movements from nominal service values.
- GST outward-supply records alone capture all non-market services.
- The October approach paper itself establishes that expanded coverage is already implemented.
How many of the above statements are correct?
(a) Only one (b) Only two (c) All three (d) None
Answer: (a) Only one
Explanation:
Only the first statement is correct. GST records cannot alone capture the omitted non-market activities; the October expansion is a proposal under consultation.
Prelims MCQ 2
Which observation most directly illustrates why spending cannot automatically be treated as service output?
(a) A ministry records its expenditure electronically. (b) Higher input prices raise expenditure without increasing services delivered. (c) A statistical agency publishes monthly data. (d) A sector contributes to national GVA.
Answer: (b) Higher input prices raise expenditure without increasing services delivered.
Explanation:
Expenditure can rise because inputs become costlier. Measuring real output requires distinguishing this from an increase in the volume of services.

Frequently Asked Questions
What is the Index of Services Production?
The ISP is a short-term indicator of changes in the volume of services output relative to a base period. Its purpose is to track real activity rather than merely changes in nominal receipts.
Has MoSPI already implemented the expanded coverage?
The 6 October release describes an approach paper and invites stakeholder comments. Education, health and residential care, and public administration and defence are proposed additions, not confirmed incorporated components of an implemented revised series.
Why can GST data not capture all services?
GST outward-supply records observe relevant taxable transactions. Core government activities, non-market services and exempt services may not generate suitable records, so the proposed expansion needs evidence beyond those returns alone.
Does higher public spending mean higher service production?
Not necessarily. Spending can increase because wages or other inputs become more expensive. Real service output requires a suitable activity measure, while quality and social outcomes require further evidence.
