First survey of unincorporated construction sector

MoSPI's National Statistical Office publishes its first deep-dive in decades into informal and own-account household construction — and feeds the numbers straight into the revised national accounts.

What happened

The Ministry of Statistics & Programme Implementation (MoSPI) released the technical report of a pilot study on construction carried out by its National Statistical Office (NSO).
It is the NSO's first dedicated effort in decades to estimate the key economic indicators of construction happening in the unincorporated sector and of own-account construction by households for their own use.
The reference period for the data is the last 365 days preceding the survey enumeration.
The pilot was run alongside the Annual Survey of Unincorporated Sector Enterprises (ASUSE) 2025, in the same First Stage Units, during July–December 2025.
The results are not a stand-alone curiosity: they feed the revised series of national accounts maintained by the National Accounts Division of MoSPI.
Construction here is bounded by the NIC (2008) codes 41, 42 and 43 — buildings, civil engineering, and specialised construction activities.

Background & context

Construction is one of the largest employers in the Indian economy and a heavyweight contributor to Gross Value Added, yet most of it is invisible to conventional enterprise surveys. A registered company building a flyover is easy to count; a mason raising a single room for a rural family, or a small unregistered contractor with a handful of hired hands, is not. This vast unincorporated tier — proprietary and partnership establishments that are not incorporated as companies and not separately registered — has long been a blind spot, and own-account household construction (a household building or extending its own dwelling for its own use, not for sale) sits even further outside the statistical net.

The Indian statistical system measures the unincorporated economy mainly through the Annual Survey of Unincorporated Sector Enterprises (ASUSE), the successor to the older periodic Unincorporated Enterprise Surveys of the erstwhile NSSO. ASUSE covers unincorporated non-agricultural establishments in manufacturing, trade and other services — but construction had been left out of its scope. This pilot is the bridge: by piggy-backing on ASUSE 2025's sampling frame and First Stage Units, the NSO tested whether construction in the unincorporated sector, and household self-construction, can be reliably captured so that the national accounts no longer have to rely on indirect or dated estimates for this slice of the economy.

The exercise belongs to a wider, ongoing effort by MoSPI to modernise India's economic statistics — the revision of the national accounts base year, the absorption of GST and other administrative data, and the move to fully tablet-based field collection. Within that programme, this pilot is the construction-sector piece: a methodological test-bed whose findings will inform how the formal estimates of construction GVA are built in the revised series.

It helps to place MoSPI itself. The Ministry of Statistics & Programme Implementation is the apex body for India's official statistical system; it houses the National Statistical Office (NSO) — formed by merging the older Central Statistics Office (CSO) and the National Sample Survey Office (NSSO) — which designs and runs the country's large-scale sample surveys. The National Accounts Division within MoSPI is the unit that compiles GDP and GVA. The same NSO machinery produces the flagship household surveys an aspirant already knows: the Periodic Labour Force Survey (PLFS) for employment and unemployment, the Household Consumption Expenditure Survey (HCES) for consumption and poverty estimation, and the ASUSE for the unincorporated non-farm enterprise economy. This construction pilot slots into that family as the missing tile — measuring a sector the others did not directly cover.

Why "unincorporated" is the right unit deserves a word. Indian enterprise statistics split the universe into the organised/incorporated tier — companies, registered factories captured by the Annual Survey of Industries and corporate filings — and the vast unorganised/unincorporated tier of proprietary and partnership units that escape those frames. Construction is unusually skewed toward the latter: small contractors, labour gangs, and self-building households dominate by number even where large firms dominate by value. Measuring only the incorporated tier therefore badly under-counts the sector's true footprint in jobs and output, which is precisely the gap this pilot was designed to probe.

For Prelims

Conducting body: National Statistical Office (NSO), under the Ministry of Statistics & Programme Implementation (MoSPI). MoSPI is the nodal ministry for India's official statistics.
Nature of release: a technical report of a pilot study — a methodological first attempt, not yet a full annual survey of the construction sector.
Two universes covered: (1) construction by unincorporated establishments / agencies, and (2) own-account construction by households for own use.
Reference period: last 365 days. Field period: July–December 2025, run jointly with ASUSE 2025 in the same First Stage Units (FSUs).
Key magnitudes: 98.54 lakh households undertook own-account construction for own use; 10.27 lakh unincorporated construction agencies were engaged.
Labour: about 77% of these agencies engaged at least one hired worker on a regular basis — pointing to a sector that is informal but not purely self-employed.
Assets & finance: average value of fixed assets per establishment ₹5.21 lakh; average outstanding loan per establishment ~₹1.40 lakh.
Output: GVA per market establishment ~₹7.98 lakh; output per establishment ₹16.25 lakh.
Access to formal credit: about 23% of rural households availed institutional funding for construction, against 13% of urban households — an unusual rural-above-urban gap worth noting.
Activity scope: construction defined by NIC (2008) codes 41 (buildings), 42 (civil engineering) and 43 (specialised construction).
Method: Computer Assisted Personal Interviewing (CAPI) — tablet-based field collection — with multi-stage stratified sampling.
Sample size: 19,154 households, 4,470 market and 717 non-market establishments across 11,981 First Stage Units.
Use of data: fed into the revised series of national accounts via the National Accounts Division of MoSPI.

What it is NOT: This is a pilot study technical report, not a regular annual survey — do not equate it with ASUSE itself, which covers manufacturing, trade and services (not construction). It is not a Census, not a survey of incorporated (registered company) construction firms, and not the same as the Periodic Labour Force Survey (PLFS) or the Household Consumption Expenditure Survey. "Own-account" construction means a household building for its own use, not contracting work sold in the market. MoSPI is a ministry, and the NSO its survey arm — not a constitutional or statutory regulatory body in the sense of, say, the RBI or SEBI.

For UPSC: MoSPI's NSO ran its first pilot in decades on unincorporated and own-account construction, alongside ASUSE 2025 (Jul–Dec 2025, reference 365 days). Anchor figures: 98.54 lakh own-account households, 10.27 lakh unincorporated agencies, ~77% using regular hired labour; data feeds the revised national accounts. Remember the family: ASUSE (unincorporated mfg/trade/services), PLFS (labour), HCES (consumption) — all NSO surveys under MoSPI.

Why it matters

Construction is among the most labour-intensive and migration-heavy parts of the Indian economy, absorbing crores of low-skilled and seasonal workers and acting as the first non-farm rung for many rural households. But because so much of it is informal, the official picture of its size, employment and value-added has rested on assumptions rather than direct measurement. A pilot that puts hard numbers on how many households self-build, how many small agencies operate, how much they invest in fixed assets, and how they finance themselves closes a genuine data gap — and better source data makes the construction component of GDP more credible.

The finance numbers carry a governance signal of their own. That only roughly a fifth of rural households (and fewer urban ones) tap institutional credit for construction tells you the sector still leans heavily on informal finance — relevant to debates on financial inclusion, housing finance and formalisation. The labour finding — that most unincorporated agencies use regular hired workers — pushes back on the lazy assumption that informal construction is all own-account or casual, and sharpens questions about social security, wage protection and the gig/informal-worker safety net.

There is a national-accounts payoff too. When the construction component of GVA rests on direct measurement rather than indirect extrapolation, the credibility of headline GDP improves — and so does the ability to target schemes. Better data on self-building households speaks to housing programmes; better data on small construction agencies speaks to credit-guarantee and skilling efforts for informal-sector units. In short, a statistical pilot of this kind is the quiet groundwork on which evidence-based policy in a large informal economy depends, and it strengthens India's standing in international comparisons of statistical capacity.

For Mains

Substantiation

Use the headline figures — 98.54 lakh self-building households and 10.27 lakh unincorporated construction agencies — as fresh, citable data on the scale of the informal/unincorporated economy when answering on the size and structure of India's informal sector.

Problematisation

The very existence of a "first pilot in decades" is itself the problem statement: India's statistical system has long under-measured informal construction, weakening the reliability of GVA/GDP estimates and policy targeting. The credit-access gap (only ~23% rural / 13% urban households using institutional funding) flags the financial-exclusion problem the data exposes.

Exemplification

A concrete example of how MoSPI is modernising official statistics — CAPI tablet-based collection, multi-stage stratified sampling, and integration into the revised national accounts series — when illustrating data-system reform and evidence-based policymaking.

Way-forward

Argue for graduating this pilot into a regular survey and folding construction into ASUSE-style annual coverage, so that the informal construction economy is measured continuously rather than estimated indirectly.

Deploys into: economic planning and the measurement of the informal/unincorporated economy (GS3.1); infrastructure and the construction sector's role in growth and employment (GS3.9); financial inclusion and data-driven governance.
