Total length of land borders with neighboring countries from the frozen public-domain CIA World Factbook snapshot.
Why This Ranking Matters
Examining Land Border Length across all countries reveals patterns that might not be obvious at the national level. Regional clusters, outlier nations, and historical trajectories all become clearer when the full global picture is assembled in a single ranking.
Global Range
Values range from 0 km (Samoa) to 22.5K km (China) — an infinitely large difference across 241 countries.
Regional Patterns
Asian countries lead with 7 entries in the top 20, though representation spans multiple continents. Regional factors clearly play a role, but outliers from other parts of the world show that national policy and geography matter as much as continental trends.
The distribution is highly right-skewed — a few countries have exceptionally high values that pull the average well above the median. The median (1.1K km) is far more representative than the mean (2.3K km).
Notable Outliers
The top of the ranking is competitive: China and Russia are separated by only 0%, indicating that the leading positions could shift with updated data.
