Global Cognitive Disability Prevalence Among Adults Aged 45-54

World Bank data from the Disability Data Hub estimates the adjusted prevalence of cognitive disabilities for the global population aged 45 to 54. It provides a percentage metric for individuals reporting at least a lot of functional difficulty. The dataset supports analysis of aging and disability trends.

Use Cases

• Analyze the relationship between age group (45-54) and reported cognitive disability prevalence across countries.
• Benchmark national cognitive disability rates against global or regional averages using the percentage metric.
• Model temporal trends in cognitive disability prevalence for the middle-aged demographic if multiple years are available.
• Correlate cognitive disability prevalence with other socioeconomic or health indicators from World Bank datasets.

Strengths

• Data originates from the authoritative World Bank and Disability Data Hub.
• Focuses on a specific, policy-relevant age demographic (45-54 years).
• Provides an adjusted prevalence metric for cross-country comparability.

Limitations

• Unknown sample size or underlying survey methodology for each country.
• Limited to a single age bracket, preventing analysis of full age spectrum.
• Potential for variation in disability assessment criteria between nations.
