For measuring unincorporated sector of the economy, Ministry undertakes Annual Survey of Unincorporated Sector Enterprises and publishes quarterly and annual results

1. At a Glance

• ASUSE (Annual Survey of Unincorporated Sector Enterprises) is MoSPI's flagship survey measuring the unincorporated non-agricultural sector — enterprises not registered under the Companies Act. [1]
• It is the largest enterprise survey in India by number of establishments annually surveyed. [2]
• Covers manufacturing, trade, and other services (excludes construction and agriculture). [1]
• Relevant for Prelims (survey nomenclature, launch year, coverage) and Mains (informal sector measurement, employment data, GVA estimation). [1]

2. Why in the News

• MoSPI released a press note on 27 July 2026 reiterating that ASUSE is its instrument for measuring the unincorporated sector, alongside quarterly and annual publication of results. [3]
• This came in context of MoSPI's release of the trial Index of Services Production (ISP) on 14.07.2026, which covers the formal sector — ASUSE was cited as the complementary tool for the unincorporated/informal sector. [3]
• MoSPI also released the ASUSE 2025 Press Note (reference period January–December 2025) and a Quarterly Bulletin (QBUSE) Q1+Q2 report in 2025-26. [4][5]

3. Background & Evolution

• ASUSE was conceptualized as a regular annual survey and launched in 2021-22, replacing the earlier periodic (roughly quinquennial) NSSO surveys on unorganised enterprises. [1][2]
• Survey rounds so far: ASUSE 2021-22 and 2022-23 (combined results released), ASUSE 2023-24 (reference/survey period October 2023–September 2024), and ASUSE 2025 (reference period January–December 2025 — a shift from the earlier October–September reference to a calendar-year reference). [6][7][4]
• MoSPI introduced a Quarterly Bulletin of Unincorporated Sector Enterprises (QBUSE) as the quarterly edition of ASUSE, giving more frequent (though smaller-sample) snapshots between annual releases. [2]

5. Multi-Dimensional Analysis

Economic

• Fills a critical data gap: the unincorporated/informal sector contributes substantially to GDP and employment but was historically measured only via infrequent NSSO rounds. [1]
• Enables better estimation of informal-sector GVA, feeding into National Accounts Statistics compilation. [1]

Administrative

• Annual cadence (vs earlier quinquennial surveys) improves timeliness of informal-economy statistics for policymaking. [2]
• Quarterly bulletin (QBUSE) trades sample size for frequency — MoSPI itself cautions users to interpret quarterly movements with caution due to sampling variability. [2]

Social

• Captures employment trends in the sector employing the bulk of India's non-farm workforce, relevant to labour and livelihood policy. [1]

Scientific/Statistical Methodology

• Complements MoSPI's parallel effort to measure the formal sector via the new trial Index of Services Production (ISP), released 14.07.2026, covering 19 sub-sectors using GST outward-supply data. [3]
• Reference period changed from a fiscal-offset year (Oct–Sept) in ASUSE 2023-24 to a calendar year (Jan–Dec) in ASUSE 2025 — a methodological shift aspirants should note. [7][4]

6. Recent Developments (last 12-18 months)

• 14.07.2026: MoSPI released trial Index of Services Production (ISP), covering the formal sector, prompting reiteration of ASUSE's role for the unincorporated sector. [3]
• 27.07.2026: PIB press release reaffirms ASUSE as MoSPI's tool for the unincorporated sector, with quarterly and annual publication. [3]
• MoSPI released the ASUSE 2025 Press Note (reference period Jan–Dec 2025). [4]
• MoSPI released a Quarterly Bulletin (QBUSE) for Q1+Q2 of the ASUSE cycle. [5]
• Earlier: ASUSE 2023-24 results released, reference/survey period October 2023–September 2024. [7]

7. Prelims Hooks

• ASUSE = Annual Survey of Unincorporated Sector Enterprises, conducted by MoSPI. [1]
• ASUSE launched in 2021-22, replacing earlier periodic NSSO surveys on unorganised enterprises. [1][2]
• ASUSE excludes construction and agriculture from its coverage. [1]
• Quarterly edition of ASUSE is called QBUSE (Quarterly Bulletin of Unincorporated Sector Enterprises). [2]
• ASUSE is described as India's largest enterprise survey by number of establishments surveyed annually. [2]
• ASUSE 2023-24 reference/survey period: October 2023 to September 2024. [7]
• ASUSE 2025 reference period shifted to January 2025–December 2025 (calendar year). [4]
• Establishments surveyed: ~5 lakh in ASUSE 2023-24 vs 6.5 lakh+ in ASUSE 2025. [2]
• Total estimated establishments grew from 7.36 crore (ASUSE 2023-24) to 7.92 crore (ASUSE 2025), a 7.97% rise. [2]
• Unincorporated non-agricultural sector employed 12+ crore workers (Oct 2023–Sept 2024), up over 1 crore from 2022-23. [1]
• MoSPI's trial Index of Services Production (ISP) was released on 14 July 2026, covering the formal services sector (19 sub-sectors) using GST data — distinct from ASUSE, which covers the informal/unincorporated sector. [3]
• ISP is compiled using GST outward-supply data and other administrative data on a monthly basis. [3]

8. Mains Relevance

• GS-III: Indian Economy — issues relating to planning, mobilization of resources, growth, development, employment; statistical infrastructure of the economy.
• GS-II (secondary linkage): Government policies and interventions for informal-sector welfare.
• Possible question stems:
• "Discuss the significance of measuring the unincorporated sector for India's national income accounting. How does ASUSE address the data gap left by the formal-sector-centric measures?" (GS-III)
• "Examine the challenges in capturing informal economic activity through statistical surveys in India, with reference to ASUSE." (GS-III)
• "Formal and informal sector statistics in India often diverge in measurement approach and frequency — analyse with reference to ASUSE and the newly introduced Index of Services Production." (GS-III)

9. Related Topics to Study Next

• Periodic Labour Force Survey (PLFS) — complementary employment data source, also by MoSPI/NSO.
• National Accounts Statistics (NAS) / GDP back series — ASUSE data feeds into GVA estimation for the unorganised sector.
• Index of Services Production (ISP) — MoSPI's parallel formal-sector measurement tool, directly linked to this news item. [3]
• MSME sector and Udyam Registration — overlaps significantly with unincorporated enterprises.
• Economic Census — historical predecessor for enterprise-level data before ASUSE's annual cadence.
• GST data usage in official statistics — growing trend of administrative data replacing survey-only approaches.
• Informal/unorganised sector definitions (NCEUS report) — conceptual base for distinguishing incorporated vs unincorporated enterprises.

10. Common Errors / Trap Areas

• Confusing ASUSE (unincorporated/informal sector) with the Index of Services Production (ISP) (formal sector) — the two are complementary, not the same survey. [3]
• Assuming ASUSE covers construction — it does not; construction is excluded. [1]
• Mixing up the reference periods across rounds: ASUSE 2023-24 used Oct–Sept, while ASUSE 2025 shifted to calendar year (Jan–Dec). [7][4]
• Attributing ASUSE to NSSO/NSO alone — it is conducted under MoSPI, with NSO as the implementing wing, but the survey brand is MoSPI's. [1]
• Confusing the quarterly bulletin (QBUSE) results with full annual ASUSE estimates — quarterly figures have smaller sample sizes and higher variability; MoSPI itself flags this caveat. [2]
