Source: computed from UN WPP 2024 per-country annual population projections (medium variant). A country is "past peak" if its population stopped rising before 2026, and "still growing in 2100" if its 2100 population is its highest and above its level a decade earlier.

Fastest-growing and fastest-shrinking countries by 2050

UN WPP 2024 · % change 2026 to 2050

The fastest-growing countries are led by Democratic Republic of the Congo (87.4% by 2050); the fastest-shrinking by Bosnia and Herzegovina (−21.2%). Both lists are limited to countries with at least 1 million people in 2026, so the ranking reflects countries with real demographic weight.

How UN projections work

Low variant

A lower-fertility scenario. By 2100 it gives a world population of about 6.99 billion.

Medium variant (shown here)

The UN's central projection, used on this page. It gives 10.18 billion in 2100.

High variant

A higher-fertility scenario. By 2100 it gives about 14.40 billion.

The low and high variants are lower- and higher-fertility scenarios, not probabilities. For a probability range, the UN publishes prediction intervals: the 95% interval for 2100 is 9.05 to 11.44 billion, and for 2050 it is 9.42 to 9.90 billion.

Population figures are mid-year (July 1) totals; changes are computed from the values shown. Source: UN World Population Prospects 2024, medium variant. "Peak year" is the year UN projects each country's population reaches its maximum within 1950 to 2100.

Frequently Asked Questions

What will the world population be in 2050?

9.66 billion, up from 8.30 billion in 2026 (UN medium variant). About two-thirds of the increase (882 million of 1.36 billion) is in Africa; Asia adds 417 million, while Europe and Eastern Asia shrink.

What will the world population be in 2100?

10.18 billion in the UN medium variant. The UN's 95% prediction interval for 2100 is 9.05 to 11.44 billion; its low- and high-fertility variants give 6.99 and 14.40 billion.

When will the world population peak?

In 2084, at 10.29 billion, in the UN medium variant.

Which countries will grow fastest by 2050?

By percentage, among countries with at least 1 million people: DR Congo +87%, Central African Republic +86%, Angola +85%, Somalia +83%, Niger +82% — each growing +82% to +87%. By the number of people added: India +203.0M, Nigeria +116.8M, Pakistan +112.6M, DR Congo +101.8M, Ethiopia +86.1M.

Which countries will shrink fastest by 2050?

By percentage: Bosnia and Herzegovina −21.2%, Moldova −20.6%, Lithuania −19.2%, Ukraine −19.1%, Bulgaria −19.0%. By the number of people lost: China −152.6M, Japan −17.3M, Ukraine −7.5M, Russia −7.3M, Italy −7.0M.

How certain are UN population projections?

The UN publishes probability ranges: the world's 95% prediction interval is 9.42 to 9.90 billion for 2050 and 9.05 to 11.44 billion for 2100.

What's the difference between the low, medium and high variants?

Medium is the UN's central projection, used on this page. Low and high assume lower or higher fertility and give 6.99 and 14.40 billion in 2100. They are scenarios; the 95% prediction interval is the UN's probability range.

Where does this data come from?

UN World Population Prospects 2024, medium variant, total population on 1 July for 1950 to 2100. Variants and prediction intervals come from the same UN release.

Sources & Methodology

Primary source: UN World Population Prospects 2024 — annual mid-year (1 July) total population for 194 countries, 1950 to 2100, medium variant.
Variants and intervals: the low and high variants are lower- and higher-fertility scenarios; the 80% and 95% prediction intervals are the UN's probability ranges. Both come from the same UN release.
