Belgium Population Pyramid 2065
Belgium in 2065
By 2065, the population of Belgium is expected to reach 11,577,020. Ten years before, in 2055, the projected population is still 11,790,123 — a ten-year decline of 1.8%.
Half of the population would be younger than 48.4 years, with 13.0% children under 15 and 29.1% aged 65 or older. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
