Cognitive Difficulty Prevalence Among Adults Aged 45-54

Adjusted prevalence data measures the percentage of persons aged 45 to 54 years reporting some degree of cognitive difficulty. The dataset is produced by the Disability Data Hub (DDH) and hosted by the World Bank as part of its collection on cognitive health and aging populations. Specific temporal coverage and row counts are not provided.

Use Cases

• Analyze trends in the 'adjusted prevalence' metric over time for the 45-54 age cohort.
• Compare cognitive difficulty rates across different countries or regions using the standardized indicator.
• Correlate the prevalence percentage with other demographic or health indicators available from the same source.
• Model early-onset cognitive difficulty as a public health outcome for the specified age group.

Strengths

• Provides a standardized 'adjusted prevalence' metric for consistent comparison.
• Focuses on a specific and understudied age cohort (45-54 years) for cognitive health.

Limitations

• Sample sizes, data collection methods, and underlying population counts are unknown.
• Lacks granularity as it is a single aggregated percentage without individual-level data or sub-group breakdowns.
• Unknown temporal coverage limits analysis of trends over time.
