Thane district in the state of Maharashtra holds the distinction of being the most populous district in India. According to the 2011 Census, Thane had a population of over 1.1 crore (11 million) people, surpassing even many states in terms of population. Located adjacent to Mumbai, Thane has seen rapid urbanization and migration due to its proximity to India’s financial capital. It includes cities like Navi Mumbai, Kalyan-Dombivli, Bhiwandi, and Mira-Bhayandar, which have contributed significantly to its demographic expansion.

Thane district is known for its diverse landscape, comprising urban areas, industrial zones, and picturesque natural surroundings, including lakes and hills. The district is a major residential and commercial hub, playing a vital role in the Mumbai Metropolitan Region (MMR). Despite its dense population, Thane also preserves cultural and historical landmarks, with a blend of Marathi heritage and cosmopolitan growth. The government faces challenges in managing infrastructure, transportation, and public services, but development efforts are consistently underway to accommodate its booming population.
