Brunei Darussalam Population Pyramid 2040
Brunei Darussalam in 2040
United Nations projections (medium variant) put the population of Brunei Darussalam at 505,975 in 2040. That would be 4.9% more than in 2030 (482,446).
The median age is projected at 40.0 years, with 23.9 children under 15 and 20.2 people aged 65 or over for every 100 people of working age (15–64). This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
