📊 Ministry of Statistics Revises Consumer Price Index (CPI) Base Year to 2024

Introduction

In a significant move to modernize India’s inflation measurement system, the Ministry of Statistics and Programme Implementation (MoSPI) has officially revised the Consumer Price Index (CPI) base year from 2012 to 2024. This change represents the most substantial update to India’s primary inflation metric in over a decade and aims to align inflation measurement with the current consumption patterns of Indian households.

What Is the Consumer Price Index (CPI)?

The Consumer Price Index (CPI) is a macroeconomic indicator that tracks changes in the prices of a representative basket of goods and services commonly purchased by households. It is widely used as a measure of retail inflation and plays a crucial role in economic policy, including:

Monetary Policy decisions by the Reserve Bank of India (RBI)
Adjustment of dearness allowances, pensions, and wages
Formulation of welfare programmes and price-indexed policies
Economic analysis and international comparisons

Why Was the CPI Base Year Updated?

Economic conditions, technology, and consumption behaviour have changed dramatically since 2012. Items like digital subscriptions, online services, and modern transportation modes were not part of the older index. Updating the base year ensures:

Better representation of current consumption patterns
Inclusion of emerging goods and services (e-commerce, OTT, app-based services)
More accurate and reliable inflation data for policymaking

Key Changes in the Revised CPI

📌 New Base Year

Old Base: 2012=100
New Base: 2024=100
MoSPI’s shift reflects recent household consumption surveyed under the Household Consumption Expenditure Survey (HCES) 2023–24.

📌 Expanded CPI Basket

Old CPI Items: 299
New CPI Items: 358
This expansion includes more items relevant to modern lifestyles such as digital services, smartphones, online purchases, and international airfares.

📌 Re-weighted Components

Food & Beverages: Reduced weight (from around 45.86% to 36.75%)
Housing: Increased weight (from 10.07% to 17.66%)
This reflects growing household spending on housing and reduced importance of food expenditures as incomes rise.

How Inflation Data Will Be Collected

Price data for the new CPI will be collected from 2,860 markets across 434 towns, including urban and rural areas, and for the first time also from online platforms.

When Will the New CPI Series Start?

The first CPI Index using the 2024 base year will be released on 12 February 2026. A linking factor will ensure smooth transition and continuity between the old (2012) and new (2024) CPI series.

Implications for India’s Economy

This revision will have wide-ranging impacts:

Monetary Policy: May influence how inflation targeting is framed
Economic Analysis: Better insights into consumption and price changes
Wages & Allowances: Could affect how dearness allowance and pensions are adjusted
International Comparisons: CPI becomes more comparable with global indices

🧠 Why This News Is Important for Government Exam Preparation

Essential for Economic Awareness

Understanding inflation and its measurement is crucial for government competitive exams like SSC, UPSC, Banking, Railways, and Defence Services, as questions about macroeconomic indicators frequently appear under Economy & Policy sections.

Policy Impact and Current Affairs Relevance

The revision of the CPI base year to 2024 signals major changes in India’s economic statistical framework, which directly impacts:

Monetary Policy Decisions by the RBI
Fiscal planning and social welfare schemes
Budgetary allocations and allowance adjustments
Inflation forecasts and economic analysis

With the Indian economy rapidly evolving, students preparing for exams must be aware of how statistical indicators like CPI are updated to reflect current economic realities, including digital consumption and urbanisation trends. These concepts can help answer objective-type questions as well as enhance essay and interview responses.

📚 Historical Context: Evolution of CPI Base Year in India

What Is a Base Year?

A base year is the reference year from which price index calculations begin. It sets the benchmark for tracking price changes over time. Base years are periodically updated to ensure that price tracking accurately reflects contemporary consumption patterns.

Past Base Year Revisions

Historically, India has periodically updated key macroeconomic series:

Prior CPI base years included 2010 and 2012
GDP base years have been revised multiple times, most recently to 2022-23
CPI base year update cycles typically occur every 5–10 years to factor in structural economic changes

Why Periodic Review Matters

As economies evolve, households begin spending on new services and products. Without updating the base year, the CPI fails to capture these shifts, leading to inaccurate inflation measurement and possibly misinformed policy decisions.
