Stroke Mortality Rates for US Adults by County, 2019-2021 Average

Age-standardized stroke mortality data for US adults aged 35 and older, aggregated as a 3-year average from 2019 to 2021. The dataset is sourced from the National Vital Statistics System and includes spatially smoothed county-level rates. Data can be stratified by sex and race/ethnicity, and is published by data.cdc.gov.

Use Cases

• Analyze geographic disparities in stroke mortality using LocationDesc, Y_lat, and X_lon columns.
• Model mortality rate (Data_Value) by demographic strata using Stratification1 and Stratification2 columns.
• Compare state-level (LocationAbbr) versus county-level (GeographicLevel) trends in cardiovascular disease (Topic).
• Validate spatial smoothing techniques by examining raw and processed rates across Counties and States columns.

Strengths

• Data is age-standardized and spatially smoothed, enabling direct geographic comparisons.
• Includes multiple stratification dimensions (Stratification1, Stratification2) for demographic analysis.
• Published by the authoritative data.cdc.gov organization and updated on 2025-02 04.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The dataset represents a 3-year average (2019-2021), not individual annual time series.
