Methodology
What this measures: Age-standardized prevalence of hypertension among adults aged 30 to 79 years, expressed as a percentage. Higher values indicate a greater proportion of the population has high blood pressure.
How the data is collected: Data compiled by the World Health Organization using standardized methodologies to ensure comparability across countries and time periods.
How the ranking is computed: Countries are ranked from lowest to highest hypertension prevalence, with lower percentages receiving better ranks since reduced hypertension rates indicate better population health outcomes.
Coverage: 192 countries with data available for 1990 and 2019.
Limitations:
Data collection methods and diagnostic criteria may vary between countries
Age-standardization allows comparison but may not reflect actual demographic composition
Limited to two time points, preventing analysis of recent trends
Prevalence rates reflect detection and healthcare access, not just disease occurrence
Rankings show association, not causation with health policies or interventions
