Global Cognitive Difficulty Prevalence Estimates

World Bank data from the Disability Data Hub provides adjusted prevalence estimates for persons with any degree of cognitive difficulty. The dataset measures this prevalence as a percentage of the population. It is part of a collection of global disability statistics.

Use Cases

• Analyze trends in cognitive difficulty prevalence across countries and years using the core percentage metric.
• Benchmark national cognitive health outcomes against regional or global averages using the adjusted prevalence figures.
• Model correlations between cognitive difficulty prevalence and other socioeconomic or health indicators available in related datasets.

Strengths

• Data is produced by the World Bank, a major international institution.
• Focuses on a standardized, adjusted prevalence metric for cross-country comparison.

Limitations

• Specific sample sizes, row counts, and column details are unavailable.
• The methodology for 'adjusted prevalence' calculation is not described here.
• Data recency and update frequency are unknown.
