Belgium Population Pyramid 2029
Belgium in 2029
United Nations projections (medium variant) put the population of Belgium at 11,813,659 in 2029. Ten years before, in 2019, the projected population is 11,490,618 — 2.8% lower.
The median age is projected at 43.8 years, with 23.3 children under 15 and 36.2 people aged 65 or over for every 100 people of working age (15–64). The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
