Updated socioeconomic classification: revised modified B. G. Prasad and modified Kuppuswamy scales for January 2025

Background: Socioeconomic status (SES) is critical in determining health outcomes, access to healthcare, and overall well-being. Accurate SES classification is essential in epidemiological research and health planning. The B. G. Prasad and Kuppuswamy scales are widely used for SES classification in India, but they require periodic updates to reflect economic changes. This study presents the updated income classifications for the modified B. G. Prasad and modified Kuppuswamy scales for 2025. Methods: The SES scales were revised by incorporating the latest consumer price index for industrial workers (CPI-IW) data for January 2025. Results: The updated modified Kuppuswamy and modified B. G. Prasad scales for 2025 were obtained using revised CPI (IW). Conclusions: This update ensures that these scales remain relevant, aiding researchers and policymakers in accurately assessing socioeconomic disparities.
