Because Manimajra is administratively part of the Chandigarh Municipal Corporation, its specific population data is often aggregated into Chandigarh's overall census figures. However, it is one of the most densely populated zones in the Union Territory, with an estimated population exceeding 100,000 residents.
The demographic makeup is highly diverse. It houses a mix of original residents whose families have lived in the town for generations, migrants from neighboring states (like Punjab, Haryana, and Himachal Pradesh), and professionals working in Chandigarh's nearby IT sector. The primary languages spoken are Hindi, Punjabi, and English. Hinduism and Sikhism are the majority religions, with vibrant local communities supporting numerous temples, gurdwaras, and mosques.
