Why is Brunei least populated in Asia?

Brunei's low population is primarily due to its small land area and historical factors. As a small, oil-rich nation on the island of Borneo, it has a limited geographic space to support a larger population. Additionally, its economic stability and wealth have led to a high standard of living, which can result in lower population growth rates. Furthermore, Brunei's government policies and emphasis on maintaining a balanced population size have also contributed to its status as the least populated country in Asia.
