Which state (or UT) has the highest density of population (density/sq.km)??????

Delhi (National Capital Territory) has India's highest population density at approximately 11,297 persons per square kilometer. As a small urban territory with massive population, Delhi's density far exceeds that of any state. While Bihar (1,106) and West Bengal (1,029) are the densest states, and Chandigarh is a dense UT, Delhi's combination of small area (1,484 km²) and large population (~16.8 million) makes it the densest. The high density reflects Delhi's role as India's primary urban magnet and economic hub.
