A1. Index Construction Methodology

General Principles

All indices follow a standardized construction methodology:

Index_t = Σ(w_i × normalize(X_it)) / Σw_i where: X_it = Raw value of component i at time t w_i = Weight assigned to component i normalize() = Min-max normalization to [0,1]

Normalization Formula

normalize(X) = (X - X_min) / (X_max - X_min) For reverse indicators: normalize_reverse(X) = 1 - normalize(X)

A2. Statistical Suppression Index (SSI) Details

Component Weights and Graded Severity

SSI is a 0-10 weighted sum of graded suppression severities: SSIt = Σ(weighti × severityit), severity ∈ [0,1] (1.0 = full suppression / discontinuation, ~0.7 = methodology dispute, ~0.3 = delay or post-resolution scar). Six documented streams; weights sum to 10. The UPA years (2004-2013, shaded) record nothing, so SSI = 0. Both eras are computed identically in data/compute_indices.py. Cell values are the annual severity; published third-party data is not involved — these are author-coded severities anchored to datable events (see notes).

20251.30011.306.55
20261.20011.306.40
Key Finding: SSI was 0 across the UPA decade, then climbed to a peak of 9.0 in 2021-2022 — the COVID-mortality undercount (official ~0.5M deaths vs 3-5M excess) stacking on top of the census delay, the withheld consumption survey, the shelved GDP back-series and the permanent NSSO→NSO merger. It remains elevated at 6.4 in 2026: the acute events eased, but the institutional damage (merger, unresolved back-series) is permanent and the data scars persist.

A3. Fiscal Centralisation Index (FCI) Components

Detailed Component Calculation

FCI_t = (1/6) × [C1_t + C2_t + C3_t + C4_t + C5_t + C6_t] Where: C1_t = minmax(Cess_Share_t) C2_t = 1 - minmax(Devolution_t) C3_t = 1 - minmax(States_Own_Revenue_t) C4_t = minmax(CSS_Share_t) C5_t = Borrowing_Restrictions_t ∈ {0, 0.5, 1} C6_t = GST_Centralisation_t ∈ [0,1] (0 pre-2017; full once GST compensation ended mid-2022)

202614.531.438.139.00.01.000.68
Note: Six components, each min-max normalised over the full 2004-2026 sample, so FCI is relative: 0.00 = least-centralised year (2004), ~0.92 = most (2020). UPA average 0.09 vs 0.57 under NDA. The new GST component captures the structural loss of independent state taxation in 2017 (cesses and CSS are symptoms; GST is the regime shift), phasing to full weight once GST compensation ended in June 2022. NDA component values (2014-2024) are budget / Finance-Commission anchors; UPA values interpolate official anchors (12th-15th FC devolution; Receipt-Budget cess and CSS shares).

A4. Democratic Quality Index (DQI) Calculations

Four-Component Geometric Mean

DQI_t = (V_t × F_t × R_t × C_t)^(1/4) Where: V_t = V-Dem Liberal Democracy Index (0-1) F_t = Freedom House aggregate score / 100 R_t = (180 - RSF_rank_t) / 180 C_t = V-Dem Core Civil Society Index (0-1)

All four are published third-party measures. The Civil Society Index is added because press-freedom rank barely separates the eras (India was mediocre throughout), whereas civil-society space collapsed from 0.669 to 0.302 under NDA — the dimension a headline democracy score flattens. (V-Dem also reclassified India from electoral democracy to electoral autocracy in 2019.)

20260.26066/100157/1800.3020.29
Key Finding: DQI fell from a UPA-era average of 0.57 (peak 0.61) to 0.29 by 2026, and from 0.49 in 2014 — with the steepest drop after 2019, the year V-Dem reclassified India as an electoral autocracy. The geometric mean is now pulled hardest by the collapse in civil-society space (0.669 → 0.302), not just press freedom.

Correction, 15 August 2026. The two V-Dem columns above previously held approximated values whose pre-2014 entries were too high (Liberal Democracy Index 0.555 for 2014 against a published 0.488; Core Civil Society Index 0.87 against a published 0.669). That inflated the baseline and therefore exaggerated the measured decline — an error running in this project’s own favour. Both columns are now the published V-Dem series verbatim (v2x_libdem and v2xcs_ccsi). The UPA-decade mean falls from 0.59 to 0.57 and the 2014 value from 0.54 to 0.49; the 2026 value is unchanged at 0.29.

A4b. Unpaid Household Work: Time Use Survey Data

National accounts place own-account household services outside the production boundary, so none of the GDP figures in this appendix include them. The hours are nonetheless measured. Source: NSO Time Use Survey, January–December 2019 and January–December 2024; the later round covered about 4.5 lakh persons in 1.3 lakh households. Ages 15–59. Minutes are the daily average among participants, not across the whole population.

IndicatorWomen 2019Women 2024Men 2019Men 2024
Unpaid domestic services, minutes/day2992899788
Participation in unpaid domestic services, %81.283.926.145.8
Participation in employment, %21.82570.975
Caregiving, minutes/day (2024)14074
Caregiving participation, % (2024)4121.4
Derived result: the participant gap in unpaid domestic services was 299 − 97 = 202 minutes in 2019 and 289 − 88 = 201 minutes in 2024. Male participation rose from 26.1% to 45.8% over the same period while minutes among participants fell for both sexes, so the gap closed by 1 minute in five years. Female employment participation rose 21.8% → 25%.

A4b.1 Published valuations

Estimates of what this work would be worth, as a share of GDP. The spread reflects valuation method, not uncertainty in the hours. This project publishes the range and adopts none of them; no GDP figure anywhere in this assessment is adjusted.

EstimateMethod% of GDP
SBI Ecowrap (2023)minimum-wage valuation7.5%
Ministry of Women and Child Development (2024 submission)not fully specified15–17%
Generalised opportunity cost, 2019-20opportunity cost24.6%
Economic and Political Weekly (2024), 2022-23replacement and opportunity cost26–36%
Replacement cost method, 2019-20replacement cost32.4%

Bearing on the employment series: female labour force participation of ~21% in the main tables is customarily read as an absence of work, while the Time Use Survey records 83.9% of women aged 15–59 in unpaid domestic work on the reference day. The participation figure measures the absence of work the accounts recognise. How much of the gap is behavioural rather than definitional is unresolved here.

A5. Employment Elasticity Estimation

Methodology

Employment Elasticity = (%ΔEmployment) / (%ΔGDP) Log-linear specification: ln(E_t) = α + β×ln(Y_t) + γ×X_t + ε_t Where: E_t = Employment at time t Y_t = Real GDP at time t X_t = Control variables β = Employment elasticity
Period GDP Growth % Employment Growth % Elasticity 95% CI
2004-2009 8.4 0.8 0.10 [0.08, 0.12] 0.72
2009-2011 8.5 0.4 0.05 [0.02, 0.08] 0.65
2011-2016 6.7 0.1 0.01 [-0.02, 0.04] 0.58
2016-2020 5.2 -1.2 -0.23 [-0.28, -0.18] 0.81
2020-2023 7.8 8.6 1.11 [0.95, 1.27] 0.69
Note: The 2020-2023 elasticity of 1.11 reflects distress employment in informal sector post-pandemic, not quality job creation.
