Brunei Darussalam Population Pyramid 2045
Brunei Darussalam in 2045
In 2045, Brunei Darussalam is projected to have a population of 514,052 people. Compared with 2035, when the projection stands at 495,290, that represents growth of 3.8% over ten years.
Half of the population would be younger than 41.3 years, with 15.9% children under 15 and 16.7% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
