What Hypertension Prevalence Measures
Age-standardized share of adults aged 30-79 with hypertension, from WHO data.who.int.
Why This Ranking Matters
Examining Hypertension Prevalence 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 19.8% of adults (Peru) to 56.6% of adults (Paraguay) — a 3-fold difference across 193 countries.
Regional Patterns
European countries lead with 9 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.
Values are broadly distributed across countries, with the middle 50% ranging from 33.6% of adults to 42.4% of adults. The overall spread from 19.8% of adults to 56.6% of adults reflects significant global variation.
Notable Outliers
The top of the ranking is competitive: Paraguay and Lithuania are separated by only 13%, indicating that the leading positions could shift with updated data.
