About 97% of the population lives in the larger western part (Belait, Tutong, and Brunei-Muara), while only about 10,000 people live in the mountainous eastern part (Temburong District). The total population of Brunei is approximately 408,000 , of which around 150,000 live in the capital Bandar Seri Begawan. Other major towns are the port town of Muara, the oil-producing town of Seria and its neighbouring town, Kuala Belait. In Belait District, the Panaga area is home to large numbers of Europeans expatriates, due to Royal Dutch Shell and British Army housing, and several recreational facilities are located there.
