Delhi stands out as India’s most populous urban region, driven by its role as the national capital and a major hub for governance, commerce, education, and migration.

Mumbai, on the other hand, remains India’s most densely populated city despite having a smaller total population than Delhi. As the country’s financial capital, Mumbai attracts millions for employment in finance, entertainment, trade, and services.

Limited land availability, an island geography, and high real-estate demand have resulted in extremely high population density, with millions living in compact residential areas.

Gurgaon, despite being one of the least populated in the list, plays a crucial role in the Delhi-NCR region as a corporate and startup hub, known for modern office spaces, planned sectors, and rapid urban development rather than only population size.
