U.S. COVID-19 County-Level Case and Death Rates with Population Factors

United States county-level data on cumulative and weekly COVID-19 case and death rates, archived by the CDC after the public health emergency ended in May 2023. The dataset includes columns for cumulative deaths, total cases per 100k, and 7-day change rates, derived from state and local health department reports. Data collection involved automated web collection and a CDC review process to ensure accuracy before public posting.

Use Cases

• Analyze temporal trends in case and death rates using the date, cases_per_100K_7_day_count_change, and deaths_per_100K_7_day_count_change columns.
• Model the relationship between population factors (PAR, category) and cumulative health outcomes (cum_deaths, cum_cs).
• Compare COVID-19 burden across different locations and classifications using the location, classification, total_cases_per_100k, and total_deaths_per_100k columns.

Strengths

• Data sourced from a collaborative process between the CDC and state/local health departments, with a review for congruency.
• Includes 11 columns covering cumulative counts, rates per 100k, and weekly changes for detailed epidemiological analysis.
• Rates are calculated using U.S. Census Bureau population estimates for standardization.

Limitations

• Dataset is archived and was last updated on 2025-01-13; no new data will be added after May 11, 2023.
• Row count and total size are unknown, which may limit suitability assessment.
• Case and death counts are based on report date, not symptom onset date, which may affect temporal analysis.
