U.S. COVID-19 Case and Death Rates by Age Group and Bivalent Booster Status, 2023

CDC data on rates of COVID-19 cases and deaths in the United States, segmented by age group and updated (bivalent) booster vaccination status. The dataset was posted on May 30, 2023, and reflects cases through April 22, 2023, and deaths through April 1, 2023. It includes 20 columns such as crude incidence rates, age-adjusted rates, population counts, and weekly/monthly identifiers.

Use Cases

• Calculate age-adjusted incidence rate ratios (IRR) for vaccinated vs. unvaccinated groups using `age_adj_irr`, `age_adj_vax_ir`, and `age_adj_unvax_ir`.
• Analyze monthly trends in case and death rates by vaccination status using `month`, `monthly_age_adj_vax_ir`, and `monthly_age_adj_unvax_ir`.
• Compare crude and age-adjusted outcome rates across age groups using `age_group`, `crude_vax_ir`, `crude_unvax_ir`, and `age_adj_vax_ir`.
• Assess population coverage and outcome counts for different vaccination categories using `vaccinated_population`, `unvaccinated_population`, `vaccinated_with_outcome`, and `unvaccinated_with_outcome`.

Strengths

• Data includes detailed vaccination status definitions (unvaccinated, primary series, monovalent booster, bivalent booster) as described by the CDC.
• Provides both crude and age-adjusted incidence rates and rate ratios across multiple time granularities (weekly and monthly).
• Dataset contains 20 distinct columns covering outcomes, populations, rates, and demographic segmentation.

Limitations

• Last updated 2023-06-01 16:51:17; freshness should be verified as updates ceased after May 2023.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Metadata for license, author, and exact geographic scope beyond the U.S. CDC source is unspecified.
