The All-India Debt and Investment Survey (AIDIS), scheduled between July 2026 and June 2027, is a key input for estimating gross fixed capital formation, or GFCF – a core component of GDP that tracks spending on assets such as housing, land and durable goods.
“Data from AIDIS 2026-27 will be incorporated into the 2027-28 GDP estimates,” the official said.
“We will examine how its findings can be incorporated into the new series to enhance relevance,” the official added.
The survey, which collects information on household assets and liabilities, will be conducted every five years, ET reported earlier. The last round was carried out in 2019, and its findings are widely used in compiling national accounts and benchmarking investment estimates.
The Ministry of Statistics and Programme Implementation (MoSPI) is in the process of revising India’s GDP base year and updating data sources. A new GDP series, with 2022-23 as the base year, is due to be released on February 27, 2026, replacing the current 2011-12 series.
Under the revised framework, benchmark estimates for dwelling repair and maintenance costs are based on AIDIS 2019, compared with AIDIS 2013 used in the existing series.
In line with the System of National Accounts, GFCF is compiled across multiple asset categories, including dwellings, other buildings and structures, machinery and equipment, cultivated biological resources and intellectual property products. AIDIS data are used to estimate household-sector investment and also feed into intellectual property product estimates.
MoSPI will conduct AIDIS alongside the Situation Assessment of Agricultural Households survey as part of the 81st round of the National Sample Survey (NSS).
