The Ministry of Statistics and Programme Implementation (MoSPI) is undertaking the base revision exercise of the Consumer Price Index (CPI). In the process, MoSPI is revisiting methodologies, exploring new data sources and incorporating changes after comprehensive consultations with the experts, academicians, users andother stakeholders.

As a part of CPI, Housing constitutes a major component with an expenditure share of 21.67% in urban areas and 10.07% at the All-India level in the current series. Housing is a crucial indicator for the overall well-being of the households not only in India but across the world as a significant amount of their income is spent either on house rent or maintaining an owned house. Inflation based on house rent index is an important tool not only for the policy and decision makers but also for the households. Therefore, robust and relevant housing index compilation methodology for capturingits actual movement every month is of utmost importance. Based on the feedback received from various stakeholders, experts and global best practices, MoSPI is proposing changes in the existing housing index compilation methodology.

A Discussion Paper on the proposed changes in housing index compilation methodology in the new CPI series is prepared. It provides detailed outlines of the existing methodology and proposed changes for the new series. MoSPI invites views and comments from experts, academicians, Central government Ministries/ departments, State governments, financial institutions and other stakeholders on the proposed housing index compilation methodology. This is the third in a series of discussion papers being released as part of the CPI base revision exercise. Two discussion papers on the “Treatment of Free PDS Items in CPI Compilation”, were released on 23rdDecember 2024 and 4th October 2025.

The Discussion Paper is available on the MoSPI website www.mospi.gov.in and CPI warehousewww.cpi.mospi.gov.in. Comments and suggestions may be sent to  psd-nso2020@mospi.gov.in by 20^th November, 2025
