Many cultural and linguistic differences make Brunei Malays distinct from the larger Malay populations in nearby Malaysia and Indonesia, even though they are ethnically related and share the Muslim religion.

Brunei has a genetic nobility with the title Pengiran. The Sultan can award to commoners the title Pehin, the equivalent of a life peerage awarded in the United Kingdom. The Sultan also can award his subjects the Dato, the equivalent of a knighthood in the United Kingdom, and Datin, the equivalent of a damehood.

The official language is Malay, but English is widely understood and used in business. Other languages spoken are several Chinese dialects, Iban, and a number of native dialects. Islam is the official religion, but religious freedom is guaranteed under the constitution.
