Countries by Population

What Population Measures

Population is a demographic indicator published by the World Bank that captures important population characteristics. Demographic metrics like this one inform government planning, healthcare provisioning, urban development, and migration policy. They are among the most frequently searched country statistics globally.

Why This Ranking Matters

Tracking Population across countries reveals global population trends, from aging societies in Europe and East Asia to young, rapidly growing populations in Sub-Saharan Africa. These patterns shape labor markets, education systems, pension sustainability, and geopolitical influence for decades to come.

Global Range

Values range from 50 (Pitcairn) to 1.42 billion (India) — a 28.39 million-fold difference across 234 countries.

Regional Patterns

Asian countries dominate this ranking, holding 10 of the top 20 positions. This strong regional concentration suggests shared economic, geographic, or policy factors that drive higher values across the continent.

The distribution is highly right-skewed — a few countries have exceptionally high values that pull the average well above the median. The median (5.74 million) is far more representative than the mean (34.71 million).

Notable Outliers

The top of the ranking is competitive: India and China are separated by only 1%, indicating that the leading positions could shift with updated data.
