Hypertension Prevalence Among US Adults By Demographic Characteristics

National estimates detail hypertension prevalence among adults aged 20 and older across various demographic subgroups. The dataset originates from the National Health and Nutrition Examination Survey, managed by the National Center for Health Statistics. Data was last updated in September 2025.

Use Cases

• Analyze hypertension ESTIMATE trends over TIME_PERIOD for specific SUBGROUP categories like gender or ethnicity.
• Compare ESTIMATE_LCI and ESTIMATE_UCI confidence intervals across different CLASSIFICATION groups to assess statistical significance of disparities.
• Model the relationship between demographic SUBGROUP features and hypertension ESTIMATE using STANDARD_ERROR for uncertainty quantification.

Strengths

• Data is sourced from the authoritative National Health and Nutrition Examination Survey (NHANES).
• Includes detailed uncertainty metrics via ESTIMATE_LCI, ESTIMATE_UCI, and STANDARD_ERROR columns.
• Covers multiple demographic dimensions through SUBGROUP and CLASSIFICATION columns.

Limitations

• Sample size (row count) and temporal coverage (TIME_PERIOD range) are unknown.
• Data granularity is limited to aggregated estimates, not individual patient records.
• Potential for geographic bias as data is specific to the United States.
