US Heart Disease Mortality Rates by County and Demographics

County-level heart disease mortality data for US adults aged 35+ from 2014 to 2016 provides a 3-year average. Rates are age-standardized and spatially smoothed, and can be stratified by sex and race/ethnicity. The data originates from the National Vital Statistics System and is published by data.cdc.gov.

Use Cases

• Analyze geographic patterns in heart disease mortality by mapping Data_Value against LocationDesc and Location 1 (state).
• Investigate demographic disparities by comparing Data_Value across Stratification1 (e.g., sex) and Stratification2 (e.g., race/ethnicity).
• Model county-level mortality risk using features like GeographicLevel, StratificationCategory1, and Year.
• Validate public health interventions by tracking changes in Data_Value_Type and Data_Value_Unit over the Year range.

Strengths

• Data covers a 3-year period (2014-2016) for temporal stability.
• Rates are age-standardized and spatially smoothed to improve comparability.
• Includes demographic stratification via Stratification1 and Stratification2 columns.

Limitations

• Data is temporally stale, representing a period ending in 2016.
• Sample size and row count are unknown, limiting assessment of statistical power.
• Geographic coverage is limited to the United States and its territories.
