Definition
Absolute decline subtracts the 2026 projected total from the 2050 total and ranks negative changes by their size in people.
2026 medium projection
See where the UN medium scenario projects the greatest reduction in the number of residents—not merely the fastest percentage decline.
The UN series provides historical estimates through 2023. Figures from 2024 onward—including 2026—are medium-scenario projections, not counts or predictions guaranteed to occur.

Absolute decline subtracts the 2026 projected total from the 2050 total and ranks negative changes by their size in people.
A large numerical decline can reshape labour supply, regional settlement, housing, schools, and care needs even when the annual percentage change appears modest.
Future migration, fertility responses, conflict, and policy can alter the trajectory. A national decline can coexist with growth in particular cities or age groups.
China leads with −152,624,996, while Taiwan is at rank 10 with −3,576,692. At the other end of the complete table, Northern Mariana Islands has −150.
Those positions describe this particular indicator, definition, and reference period. They do not imply that every country near the top has the same population pyramid or demographic path. Open the profiles to compare the underlying cohorts.
China ranks first in this comparison with −152,624,996. The table uses 2026 medium projection from UN World Population Prospects 2024.
In World Population Prospects 2024, historical estimates run through 2023 and values from 2024 onward are projections. The peak-year table labels historical and projected results separately.
Sources can use different reference dates, revisions, country definitions, estimation methods, or projection scenarios. Close ranks can also change after revisions.
