According to the last official census in 2011, the Dibrugarh Urban Agglomeration had a population of roughly 154,296, though contemporary estimates place the figure considerably higher due to urbanization and regional migration. It is one of the most populous cities in Assam.
The city boasts a highly cosmopolitan and diverse demographic profile. The population comprises ethnic Assamese, Bengalis, Biharis, Marwaris, and the Tea Tribe community (descendants of laborers brought from central India during the British era).
Hinduism is the majority religion, followed by Islam, Christianity, and Buddhism. Assamese is the primary language of daily life, though Bengali, Hindi, and English are widely spoken. Dibrugarh has a relatively high literacy rate of over 89%, reflecting its status as an educational center. The workforce is primarily engaged in services, trade, healthcare, education, and industries related to tea and energy.
