Cognitive Difficulty Prevalence Among Adults Aged 55 to 64

Adjusted prevalence data measures the percentage of persons aged 55 to 64 years with any degree of cognitive difficulty. The dataset is produced by the Disability Data Hub (DDH) and hosted by the World Bank. It focuses on cognitive health within an aging demographic.

Use Cases

• Analyze temporal trends in cognitive difficulty prevalence using the time-series structure.
• Model the relationship between age group (55-64) and cognitive difficulty rates.
• Benchmark country-level cognitive health indicators using the prevalence percentage metric.

Strengths

• Focuses on a specific, policy-relevant age demographic (55-64 years).
• Provides an adjusted prevalence metric for standardized comparison.
• Sourced from the authoritative Disability Data Hub via the World Bank platform.

Limitations

• Unknown sample size or number of countries covered limits statistical assessment.
• Lacks granularity on specific types or severities of cognitive difficulty.
• Data freshness and update frequency are unknown.
