What UNESCO World Heritage Sites Measures
Count of Wikidata World Heritage Site records credited to the country, root-normalized by UNESCO ID to avoid counting component records as separate sites.
Why This Ranking Matters
Examining UNESCO World Heritage Sites 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 sites (Mayotte) to 61 sites (Italy) — an infinitely large difference across 249 countries.
Regional Patterns
European 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 (2.00 sites) is far more representative than the mean (5.40 sites).
Notable Outliers
The top of the ranking is competitive: Italy and China are separated by only 2%, indicating that the leading positions could shift with updated data.
