QUICK ESTIMATE OF INDEX OF INDUSTRIAL PRODUCTION AND USE-BASED INDEX FOR THE MONTH OF JANUARY 2026

1. At a Glance

• Index of Industrial Production (IIP) is the volume indicator that measures short-term changes in industrial output of Mining, Manufacturing, Electricity; base year 2011-12 = 100 [1][2].
• Released as a Quick Estimate on the 28th of every month (or next working day) by the National Statistical Office (NSO), Ministry of Statistics & Programme Implementation (MoSPI) [1].
• January 2026 IIP grew 4.8% YoY, decelerating from 7.8% in Jan 2025 — relevant for GS-III "Indian Economy & Industry" and Prelims data-based MCQs [1].

2. Why in the News

• PIB release dated 02 March 2026 (PRID 2234512) — Quick Estimate of IIP for January 2026 placed industrial growth at 4.8%, against 7.8% (QE) in Jan 2025 [1].
• Coincides with MoSPI's ongoing Base Revision exercise for GDP, IIP and CPI; third pre-release consultative workshop held at Chennai on 30 Jan 2026 [3].

3. Background & Evolution

• IIP first compiled in India in 1950 with base 1937; revised bases — 1946, 1951, 1956, 1960, 1970, 1980-81, 1993-94, 2004-05, and current 2011-12 [2].
• Compiled under the Collection of Statistics Act, 2008; data flow from 14 source agencies to NSO [2].
• Quick Estimate introduced to reduce reporting lag (T+42 days) and is subsequently revised under the IIP revision policy [1].

4. Core Static Facts

• Parent Ministry: Ministry of Statistics & Programme Implementation (MoSPI); compiled by NSO [1][2].
• Base year: 2011-12 = 100 [1].
• Sectoral weights (2011-12 series): Mining ~14.4%, Manufacturing ~77.6%, Electricity ~8.0% [2].
• Use-based classification (6 categories): Primary, Capital, Intermediate, Infrastructure/Construction, Consumer Durables, Consumer Non-durables [1].
• January 2026 headline indices: IIP = 169.4 vs 161.6 in Jan 2025 [1].
• Sectoral indices Jan 2026: Mining 157.2 (4.3%), Manufacturing 167.2 (4.8%), Electricity 212.1 (5.1%) [1].
• Use-based indices Jan 2026 (growth YoY): Primary 167.9 (3.1%), Capital 124.4 (4.3%), Intermediate 182.8 (6.0%), Infrastructure/Construction 227.7 (13.7%), Consumer Durables (6.3%), Consumer Non-durables (−2.7%) [1].

5. Multi-Dimensional Analysis

• Economic
• Overall IIP at 4.8% indicates moderation from 7.8% YoY in Jan 2025 — base effect plus softness in consumer non-durables (−2.7%) signal weak rural/mass-consumption demand [1].

• Infrastructure/Construction goods at 13.7% reflects continued capex push (PM Gati Shakti, NIP) [1].

• Sectoral

• Electricity (5.1%) leads, aided by demand and capacity additions; Mining (4.3%) stable [1].

• Capital goods (4.3%) moderate — proxy for private investment cycle [1].

• Administrative / Statistical

• Quick Estimate is revisable; final figures appear in subsequent releases under the IIP Revision Policy [1].

• Base revision to a more recent year is under consultation (Chennai workshop, Jan 2026) — current base 2011-12 widely seen as outdated [3].

• Policy linkage

• IIP feeds into GVA computation (manufacturing), MPC decisions, and the PMI complementarity used by RBI [2].

6. Recent Developments (last 12-18 months)

• 02 Mar 2026 — Jan 2026 QE released: IIP +4.8% [1].
• 30 Jan 2026 — MoSPI's Third Pre-release Consultative Workshop on Base Revision of GDP, IIP and CPI, Chennai [3].
• Feb 2026 QE (PRID 2246871) also issued, indicating continuing monthly cadence [4].

7. Prelims Hooks

• IIP base year is 2011-12 [1].
• IIP is released by NSO under MoSPI, not RBI [1].
• IIP has three sectors: Mining, Manufacturing, Electricity (Construction NOT included) [1].
• Use-based classification has six categories [1].
• Quick Estimate released on the 28th of every month (next working day if holiday) [1].
• Manufacturing has the largest weight (~77.6%) in IIP 2011-12 series [2].
• Jan 2026 IIP YoY growth = 4.8% (vs 7.8% in Jan 2025) [1].
• Infrastructure/Construction Goods posted the highest use-based growth at 13.7% in Jan 2026 [1].
• Consumer Non-durables contracted (−2.7%) in Jan 2026 [1].
• Statutory backing for data collection: Collection of Statistics Act, 2008 [2].
• Electricity sector index Jan 2026 = 212.1 (highest among the three sectors) [1].
• Base revision consultations are ongoing for GDP, IIP, CPI simultaneously [3].

8. Mains Relevance

• GS-III — Indian Economy: Growth & development; Industrial policy; Macroeconomic indicators.
• Syllabus heading: "Issues relating to planning, mobilisation of resources, growth, development … Effects of liberalization on the economy, changes in industrial policy."
• Probable stems: 1. "Examine the structural weaknesses revealed by the divergence between infrastructure goods and consumer non-durables in recent IIP releases." 2. "Critically evaluate the need for base-year revision of IIP, GDP and CPI in India." 3. "IIP is a volume index of short-term industrial dynamics — discuss its limitations as a proxy for manufacturing health."

9. Related Topics to Study Next

• GVA vs GDP methodology — IIP feeds the manufacturing GVA.
• CPI & WPI — sister indices from MoSPI/DPIIT; same base-revision exercise [3].
• Eight Core Industries (ICI) — released by DPIIT, ~40% weight inside IIP.
• PMI Manufacturing (HSBC/S&P Global) — high-frequency complement.
• PLI Schemes — link to manufacturing growth trajectory.
• National Statistical Commission (Rangarajan, 2005) — institutional backbone.
• PM Gati Shakti & National Infrastructure Pipeline — drives infrastructure goods.
• Collection of Statistics Act, 2008 — legal basis for data reporting.

10. Common Errors / Trap Areas

• Wrong base year: Current base is 2011-12, NOT 2004-05 or 2012-13.
• Wrong sector list: IIP covers Mining, Manufacturing, Electricity — Construction is excluded (it falls under GDP but not IIP).
• Wrong ministry: Released by MoSPI/NSO, not RBI or DPIIT (DPIIT releases the Eight Core Industries index).
• Use-based ≠ Sector-based: Six use-based categories are a separate cross-classification, not the three sectors.
• Quick Estimate is not final — figures are revised in subsequent months under the revision policy.
