County-Level Death Counts and Rates for Injury, Overdose, and Violence in the U.S.

Death counts and death rates for drug overdose, suicide, homicide, and firearm injuries, aggregated by county of residence in the United States. The data is grouped by yearly and trailing twelve-month periods and originates from data.cdc.gov, with a last update recorded on March 10, 2026. A Bayesian model is applied to calculate rates in areas with 1-9 deaths to improve stability and protect privacy.

Use Cases

• Analyze temporal trends in mortality using the Period and TTM_Date_Range columns.
• Compare death rates (Rate, Rate_M) and counts (Count) across counties (NAME, GEOID) for different injury intents (Intent).
• Map geographic disparities in firearm injury or overdose mortality by joining on state and county identifiers (ST_GEOID, GEOID).
• Assess statistical uncertainty in modeled rates using the provided confidence interval column (Rate_M_CI).

Strengths

• Includes modeled rates for low-count areas (1-9 deaths) to protect privacy and improve stability.
• Provides data at two temporal aggregations: yearly and trailing twelve months (TTM_Date_Range).
• Contains 12 columns covering intent, geography, rates, counts, and confidence intervals.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
