We present the first ever neighbourhood-scale portrait of caste-based residential segregation in Indian cities. Residential segregation studies in Indian cities have relied on ward-level data. We demonstrate in this paper that wards cannot approximate an urban neighborhood, and that they are heterogeneous. For a typical ward, the neighbourhood-ward dissimilarity index is greater than the wardcity dissimilarity index. Using 2011 enumeration block (EB) level census data for five major cities in India – Bengaluru, Chennai, Delhi, Kolkata, and Mumbai – we show how patterns of caste-based urban residential segregation operate in contemporary India. We also present the first visual snapshot of castebased residential segregation in an Indian city using georeferenced EB level data for Bengaluru. Besides implications for policy, our analysis also points to the need for publicly available, geospatially-linked neighborhood-scale census data that includes data on economic class for a spatial understanding of economic and social stratification within Indian cities.
