It is the most industrialised district in the state, owing to the availability of flat land. Since the geology is stable the roads are in a good condition as compared to other parts of the state which suffer from landslides. The district is also famous for its Sikkim Tea, which is grown near Namchi.
The people are mainly of Nepali descent. Other ethnic groups include the Lepcha and Bhutia communities. Nepali is the most widely spoken language in the district. It also is one of the lowest populated regions of the state.
