India’s 'C' Grade in National Accounts Statistics: Flawed Data, Flawed Governance

On 29 November 2025, the International Monetary Fund (IMF) handed India a ‘C’ grade on the quality of its national accounts statistics. This marks one of the lowest ratings among major economies, starkly exposing significant institutional weaknesses. The outdated base year for GDP calculations (2011-12), last revised over a decade ago, stood as the cornerstone of the IMF’s critique—a glaring anomaly for a $3.73 trillion economy that frequently boasts of double-digit growth rates.

Why this isn’t just a technical blemish

Base year revision is more than an exercise in statistical housekeeping. For context, the UK revised its base year to 2021 in less than two years post-pandemic, capturing shifts in consumption patterns, technological integration, and price structures. In contrast, India persists with data calibrated to 2011-12—a period before GST implementation, smartphone-driven consumption, the rise of renewable energy, and the explosion of e-commerce.

The IMF’s grading system under the Data Quality Assessment Framework (DQAF) categorizes nations as A, B, C, or D. A ‘C’ grade signals weaknesses significant enough to impair accurate surveillance, a stinging rebuke for a country aspiring to be the world’s third-largest economy by 2030. Notably, India was pulled up for:

• The Consumer Price Index (CPI)—graded ‘B’—over-represents food items while ignoring shifting household expenditure patterns.
• Weak informal sector capture: The informal sector, contributing over 40% to GDP and employing 80% of the workforce, remains poorly mapped due to reliance on outdated surveys and non-digital measures.
• Integration gaps in modern databases: While MCA-21 corporate data is operational, GSTN datasets remain underutilized in estimating sectoral value addition.

India’s statistical ecosystem increasingly resembles a clogged bottleneck struggling to align with its dynamic economy. The irony is sharp—India’s headlines trumpet growth numbers, but those very metrics may hinge upon data that misrepresents reality. This is not a trivial concern; these metrics affect fiscal strategy, RBI’s monetary policy, and international investor confidence.

The institutional machinery behind subpar data

The Ministry of Statistics and Programme Implementation (MoSPI) oversees the framework under the National Accounts Statistics, yet struggles with coordination and resource limitations. The outdated base year violates global best practice, which requires revisions every five years. Sections 3 and 6 of the Collection of Statistics Act, 2008 empower MoSPI to collect economic data, but systemic delays highlight enforcement inefficiencies.

Even flagship initiatives like MCA-21—the Ministry of Corporate Affairs’ digital database—fall short of comprehensive integration. Year after year, Parliamentary Standing Committee reports flag gaps in India’s data collection processes, yet timelines for reform remain vague. Despite MoSPI’s promises to update the base year to 2020, bureaucratic inertia has consistently delayed implementation.

What the numbers really say

Contrary to official claims of “minor discrepancies,” the IMF report reveals fundamental distortions:

• India’s GDP may be systematically overstated by failing to account for structural decline in the informal sector post-demonetization and GST rollout—a gap that could inflate growth rates by 2-3 percentage points.
• Inflation data, with excessive weightage given to food (45%) under the CPI basket, obfuscates price pressures on non-food essentials like housing, healthcare, and education.
• Delayed revisions in GDP base years contributed to India’s fiscal deficit loss credibility; agencies like Moody’s cited “non-transparent methodologies” in their 2024 downgrade.

What the government presents as stability may well be opacity. Beyond methodology discussions, the larger worry lies in flawed policy stemming from flawed data. For instance, how effective can sectoral subsidies be if GDP contributions from MSMEs or agriculture are miscalculated?

The uncomfortable questions policymakers ignore

First, who safeguards the independence of India's statistical institutions? MoSPI operates under direct government directives, raising concerns of political interference when GDP numbers are framed during election cycles. Should the National Statistical Commission (NSC) have greater autonomy akin to the Election Commission?

Second, why is informal sector inclusion neglected despite constituting such a significant share? India continues to rely on proxy surveys from 2011 rather than integrating GST data, digital payment records, or Aadhaar-linked employment metrics.

Third, what explains the continued gaps despite substantial investments? The Ministry of Statistics received a ₹900 crore allocation under Budget 2024-25; where are the visible reforms? Modernizing CPI should require less than a year with adequate institutional will.

The South Korea lesson

Consider South Korea’s response to similar challenges when its informal sector faced underrepresentation during the 2018 economic analysis benchmark. The nation revised base years within five years, mandating integration of real-time tax data and aligning surveys to urbanization trends. Notably, South Korea enlisted university statisticians alongside international agencies to peer-review methodology changes—systemic reforms India could do well to study. Unlike India, the revisions were completed without political controversy, strengthening the data credibility among global investors.
