Frequently asked questions

What is the official name of Brunei?

Brunei Darussalam — in Malay, Negara Brunei Darussalam, "the Nation of Brunei, the Abode of Peace." The origin of "Brunei" is uncertain; the Sanskrit bhumi, "land," is the usual guess, and legend says the founder cried "Baru nah!" — "there!" — on choosing the site. The country gave Borneo its name.

What is the capital of Brunei?

Bandar Seri Begawan, on the Brunei River near Brunei Bay — the largest town, with about 100,000 people in the city and some 280,000 in the district around it. It was Brunei Town until 1970, when it was renamed for the late Sultan Omar Ali Saifuddien III. Beside it, on stilts in the river, stands Kampong Ayer, the water village where the sultanate began.

How big is Brunei, and how many people live there?

About 5,765 km² (2,226 sq mi) — a little larger than Delaware — on the north coast of Borneo, in two pieces separated by Malaysian Sarawak. The census of 2021 counted 429,999 people; the CIA World Factbook estimates about 492,000 and Brunei's own statisticians about 455,000, the range reflecting the counting of foreign workers. About three-quarters live in the Brunei-Muara district around the capital.

What are the highest and lowest points of Brunei?

Bukit Pagon, 1,850 m (6,070 ft), on the Sarawak border in the eastern exclave of Temburong, is the highest point; the South China Sea is the lowest. About 72 percent of the country is still forest — the Ulu Temburong National Park in the east is among the least touched rainforest in Borneo.
