Cognitive Difficulty Prevalence Among Adults Aged 55-64

World Bank data provides the adjusted prevalence of cognitive difficulty for persons aged 55 to 64 years, expressed as a percentage of that population. The dataset is curated by the Disability Data Hub (DDH) and focuses on cognitive health within an aging demographic. It is structured as a time series for public health and policy analysis.

Use Cases

• Analyze trends in cognitive difficulty prevalence over time using the time-series dimension.
• Benchmark country-level cognitive health metrics for the 55-64 age group using the prevalence percentage.
• Correlate cognitive difficulty prevalence with other socioeconomic indicators available in World Bank datasets.
• Model the projected burden of cognitive issues in pre-retirement populations using historical prevalence rates.

Strengths

• Data sourced from the authoritative World Bank and Disability Data Hub.
• Focuses on a specific, policy-relevant age cohort (55-64 years).
• Provides a standardized metric (adjusted prevalence percentage) for cross-country comparison.

Limitations

• Specific row count, column details, and temporal coverage are unknown.
• The 'adjusted' methodology is not described, which may affect reproducibility.
• Lacks granular data on the severity or causes of cognitive difficulty.
