The Delhi Belly Index (DBI) is a tongue-in-cheek economic indicator that captures the essence of urban discomfort, specifically in the context of Delhi, India. By combining metrics such as traffic congestion, air quality, and stomach upset incidence, we create a comprehensive index that reflects the overall "delhi-ness" of life in the city. This paper outlines the methodology, data collection, and initial findings of the DBI, highlighting its potential as a tool for policymakers, urban planners, and Delhi residents to better understand and address the city's unique challenges.
