What drives population change?

Births and deaths set natural change. Net migration can reinforce, reduce, or reverse that direction.

Migration contribution Reduces growth

Negative net migration slows natural growth without reversing it.

Burundi, 2024 projected: natural change +372,841 people, net migration −27,074, WPP adjustment +3, total population change +345,770. Negative net migration slows natural growth without reversing it.

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
Not reached by 2100
Rule
65+ strictly exceeds under 18

Burundi annual age balance from 1950 to 2100. Under-18 population moves from 47.4% in 1950 to 52.5% in 2023 and 25.8% in the 2100 projection. Population aged 65 and older moves from 3.2% to 2.5% and 13.1%. First annual crossover: Not reached by 2100. Estimates run through 2023 and WPP Medium projections begin in 2024.
