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.

Cambodia, 2024 projected: natural change +244,381 people, net migration −32,960, WPP adjustment +14, total population change +211,435. Negative net migration slows natural growth without reversing it.

Exact reconciliation: WPP includes a +14-person statistical adjustment. Figures are rounded to whole people.
