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.
