Belgium Population Pyramid 2055
Belgium in 2055
By 2055, the population of Belgium is expected to reach 11,790,123. Compared with 2045, when the projection stands at 11,900,984, that represents a decline of 0.9% over ten years.
The median age is projected at 46.9 years, with 24.0 children under 15 and 49.2 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.
