Selected Causes of Death in Suburban Cook County with Age-Adjusted Rates

30 specific causes of death, including opioid overdose, homicide, and Parkinson's disease, are tracked with annual death counts and rates. The Cook County Department of Public Health compiled this data from Illinois Vital Statistics. The dataset was last updated in January 2026.

Use Cases

• Analyze trends in Opioid Overdose Deaths and Drug Overdose AADR to evaluate the impact of public health interventions over time.
• Compare Homicide CDR and Firearms AADR across demographic subgroups to study disparities in violent mortality.
• Model the relationship between age-adjusted rates (e.g., Parkinson's AADR, Suicide AADR) and population aging using time-series analysis.
• Assess perinatal health outcomes by examining Perinatal Deaths counts alongside other congenital and chronic disease metrics.

Strengths

• Includes 30 distinct metrics covering death counts, crude death rates (CDR), and age-adjusted death rates (AADR) for specific causes.
• Data is sourced from the authoritative Illinois Department of Public Health Vital Statistics system.

Limitations

• Counts are suppressed for events between 1 and 4, and rates are not calculated for events less than 20, limiting analysis of rare causes.
• The geographic scope is limited to suburban Cook County, not the entire county or state.
• Sample size (row count) and temporal coverage (years) are unknown, hindering assessment of statistical power.
