What drives population change?
Births and deaths set natural change. Net migration can reinforce, reduce, or reverse that direction.
Migration contribution Reverses decline
Positive net migration is large enough to reverse natural decline.
Belgium, 2024 projected: natural change −14,077 people, net migration +36,243, WPP adjustment −3, total population change +22,163. Positive net migration is large enough to reverse natural decline.
Natural change −14,077 births minus deaths
+ Net migration +36,243 net balance
≈ Total change +22,163 people per year
Exact reconciliation: WPP includes a −3-person statistical adjustment. Figures are rounded to whole people.

AGE BALANCE · 1950–2100
Youth and older population
Annual share of the population aged under 18 and aged 65+. The crossing shows when the older group first becomes larger in the annual source series.
- First annual crossover
- 2023 · observed
- Rule
- 65+ strictly exceeds under 18
Belgium annual age balance from 1950 to 2100. Under-18 population moves from 25.2% in 1950 to 19.8% in 2023 and 15.6% in the 2100 projection. Population aged 65 and older moves from 11.0% to 20.1% and 32.5%. First annual crossover: 2023 · observed. Estimates run through 2023 and WPP Medium projections begin in 2024.
