To counter rising non-response from affluent households in gated societies, MoSPI is piloting a 'diary-based' self-reporting method for the next Household Consumption Expenditure Survey (HCES) in 2027-28. This shift is critical because the HCES data directly impacts CPI basket weights, inflation targeting by RBI, and policy making, but raises concerns about data comparability due to differential recall errors between survey methods.
