U.S. COVID-19, Influenza, and RSV Mortality Percentages by Demographics

United States provisional weekly percentages of deaths attributed to COVID-19, influenza, and RSV, broken down by sex, age group, and race/Hispanic origin. The data is sourced from the National Vital Statistics System and published by data.cdc.gov. Provisional counts are based on the flow of mortality data and are subject to change.

Use Cases

• Analyze weekly mortality trends for specific pathogens using `pathogen`, `weekending_date`, and `percent_deaths`.
• Compare disease impact across demographic groups using `demographic_type`, `demographic_values`, and `percent_deaths`.
• Track provisional death counts over time using `mmwr_week`, `year`, `total_deaths`, and `data_as_of`.
• Assess data suppression flags for statistical reliability using the `suppressed` column.

Strengths

• Includes data for three major respiratory pathogens (COVID-19, influenza, RSV) for comparative analysis.
• Provides demographic breakdowns by sex, age group, and race/Hispanic origin via `demographic_type` and `demographic_values`.
• Offers multiple file formats (CSV, JSON, XML, RDF) for accessibility.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Data is provisional and based on non-final counts, as noted in the description.
• License and author information are unknown.
