Data Sheet 2_National trends and county-level geographic disparities in mortality from ope

U.S. death certificate data from 1999 to 2023 tracks mortality from operationally defined advanced cardiovascular–kidney–metabolic (CKM) syndrome stages. The dataset, created by Kaide Xia and shared under CC-BY-4.0, includes age-adjusted mortality rates, annual percent changes, and state- and county-level metrics for 2023. It reveals an overall decline but a recent reversal in mortality trends, with significant geographic clustering of high-burden areas.

Use Cases

• Analyzing long-term mortality trends for advanced CKM stages based on age-adjusted mortality rates and annual percent changes.
• Mapping geographic inequities in disease burden based on state- and county-level mortality rates for 2023.
• Investigating the relationship between cardiovascular disease and kidney failure based on the operational definitions of CKM stage 4 and stage 4b.
• Identifying spatial clusters of high mortality using derived metrics like the Stage 4b share within Stage 4.

Strengths

• Covers a 25-year time series from 1999 to 2023, enabling long-term trend analysis.
• Includes specific mortality rates for two operationally defined disease stages (Stage 4 and Stage 4b).
• Provides geographic granularity with state- and county-level data for 2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 37.6 KB file size suggests a limited scope, likely containing summary statistics rather than raw individual-level records.
